I have a friend who runs his website on a windows 2008 server. I have set up an asp classic form to email page on his website (hisdomain.com) which takes the input from a contact form and sends it out by email.
The problem is that it only works if the email is being sent to a different domain (something#anotherdomain.com). If the email is being sent to the same domain (anything#hisdomain.com) it never arrives.
Mailer.AddAddress "someone#anotherdomain.com"
Works.
Mailer.AddAddress "someone#hisdomain.com"
Does not work.
I have hunted this site and Google for a resolution but cannot find one.
Does anyone know how to fix this issue?
Many thanks
Tog Porter
Update: It turns out he uses Gmail business to control his domain emails and there was a filter in there that bounced the messages because the sender was the same as the recipient.
Bypassing the Gmail spam filter has fixed the problem.
Use this code and replace your smtp server information

Currently we have a web form that send's emails which has stopped working months back with the migration of Office 365 at our company. I have eliminated all other code while troubleshooting and just run email portion to get the following error : "System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM ".
I have found many solutions on the web/stack overflow with the same error code, tried changing the code to proposed solutions and have had no luck.
Tried many different email aliases that are listed in our global address list with no luck for my account, different ports(25,587), different smtp addresses, and have had no luck so far.
Multiple users are stating "This code unfortunately is no longer valid with Office 365. Error message that comes up is The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM [HE1PR05CA0133.eurprd05.prod.outlook.com] " on the article linked below.
Send SMTP email using System.Net.Mail via Exchange Online (Office 365)
My code seen below.
Dim mail As MailMessage = New MailMessage
mail.From = New MailAddress("email12345#company.com")
mail.To.Add("email12345#company.com")
mail.Subject = "Test"
mail.IsBodyHtml = False
mail.Body = "Test"
Dim SmtpServer As SmtpClient = New SmtpClient
SmtpServer.Host = "smtp.office365.com"
SmtpServer.Port = 587
SmtpServer.UseDefaultCredentials = False
SmtpServer.Credentials = New System.Net.NetworkCredential("MyEmail", "MyPass")
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network
SmtpServer.EnableSsl = True
SmtpServer.TargetName = "STARTTLS/smtp.office365.com"
Try
SmtpServer.Send(mail)
Catch ex As Exception
Response.Write(ex.ToString)
End Try
As it seems this is happening to many people, I would like to know what they are doing to resolve it?
I resolved this issue by creating app password for my outlook365 account. You can create/manage app password as following.
Go to My Account >> Security & Privacy >> Additional Security Verification >> Create and manage app passwords
Create an app password and use it in your code. Hope this will solve your issue
To enable app-password you must have two factor authentication on the account and the administrator (if your account is in an organization) must allow app-passwords on the account (or in the organization)
I'm not a 365 admin and don't know all the settings.
However, we had a similar problem where the sender account did not have the setting "Modern Authentication" enabled for SMTP AUTH.
note that this worked for a long time and suddenly stopped (not sure if Microsoft did some security tightening in late February 2021)
Modern Authentication was enabled for Outlook etc (clients?),
but not for "SMTP AUTH", "IMAP", and "POP"
(I assume this is the "defaults" and recommendation is not to enable Modern Authentication unless you need it.
see the two articles below.
https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/authenticated-client-smtp-submission
Virtually all modern email clients that connect to Exchange Online mailboxes in Office 365 or Microsoft 365 (for example, Outlook, Outlook on the web, iOS Mail, Outlook for iOS and Android, etc.) don't use SMTP AUTH to send email messages.
Therefore, we highly recommend that you disable SMTP AUTH in your Exchange Online organization, and enable it only for the accounts (that is, mailboxes) that still require it. There are two settings that can help you do this:
An organization-wide setting to disable (or enable) SMTP AUTH.
A per-mailbox setting that overrides the tenant-wide setting.
Also good to know about. Will list number of "smtp auth clients".

When I first created this Classic ASP script, with the help of W3Schools, to send email, it worked fine. Now I'm having issues with sending the actual email; it appears to hang on the .Send method.
I noticed that when I set the To and From email address to just the email address, it reformats it to a "Friendly Name"/Email Address format:
myMail.From="Support#myDomain.com"
Response.Write myMail.From
The output of the Response Write is:
"Support#myDomain.com" <Support#myDomain.com>
I don't know if this was happening before, or if I should be setting the To and From fields in this format. Just to check if this is causing my problem, is there anyway to prevent these fields from being changed from just the email address?
Maybe the e-mail sending from the server now needs some kind of authentication such as setting these fields:
' Outgoing SMTP server.
objCDO.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "mail.mydomain.com"
objCDO.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objCDO.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objCDO.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60
' Type of authentication, 0=NONE, 1-Basic (Base64 encoded), and 2=NTLM.
objCDO.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
' UserID on the SMTP server
objCDO.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = "support#mydomain.com"
' Password on the SMTP server
objCDO.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "myemailpassword"
' Update config.
objCDO.Configuration.Fields.Update
The issue stemmed from the fact that the "From" email address was actually a distribution list and the account credentials used to login to the email server were not authorized to "Send As". Once that was rectified emails sent without further problems.
Thanks for the response.
I am using CDOSYS for our asp classic mail.
OK, test mail with my yahoo account, and it sends out perfectly.
However, I use my clients email and password, and it gives an error '8004020e'.
I cannot figure out why it would be doing it. My client even had their password changed just to make sure that there was not a problem with the login information.
I will go back and use my yahoo email and password, and once again, it WORKS.
Just not with theirs.
Any idea's why it will work for one account but not for the other account?
Code below:
myMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 'Send the message using the network (SMTP over the network).
myMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver") =MailServer
myMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 465
myMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = true 'Use SSL for the connection (True or False)
myMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60
' If your server requires outgoing authentication uncomment the lines bleow and use a valid email address and password.
myMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1 'basic (clear-text) authentication
myMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusername") = emailAdd
myMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendpassword") = pass
myMail.Configuration.Fields.Update
That error is usually caused by one of the following
Incorrect SMTP server / port
Incorrect login/password
FROM address not valid according to SMTP server (wrong domain)
You've verified 1 & 2, so check #3
I had to redo a script using the following start and end code in ASP using CDOSYS. (I do not know much about ASP or ASP.NET) The smtp I used requires user/pass auth. yet the E-Mail sent anyways without me putting that info. Does this mean the smtp server allows relaying with only the E-Mail address?

Set Mailer = CreateObject("CDO.Message")

Yes, this technology is being used exatcly for the simplifying the messaging:
ASP Sending e-mail with CDOSYS:
CDO (Collaboration Data Objects) is a Microsoft technology that is designed to simplify the creation of messaging applications.
CDOSYS is a built-in component in ASP. We will show you how to use this component to send e-mail with ASP.
Does this mean the smtp server allows relaying with only the E-Mail address?
It "depends" on server/mta setup:
IP whitelist
If it has other "Post offices" (domains), perhaps it allows relaying between them (aka "internal").
It's been some time since I've worked with SMTP/MTAs directly, so I'm sure those with more/current experience can provide more examples of "relay restriction rules"..
stupid me.
I did not Tshoot enough. My MTA allows domain to domain (my Email to my Email) relay. However if I tried my E-Mail to another Email (domain) I get Relay access denied.
SOLVED: Two students gave us the wrong emails, and for some reason the script refused to process more if it encountered a wrong email. I am still wondering why is it so !
I am trying to read a bunch of records from a database, and for each record I am creating some text based on some fields of the record and then sending them as email to the email address provided in the record.
The problem is the email gets sent for only about 5-10 records (it varies, once it sent 5 emails, with cc and everything, next day it sent 7).
After this it comes up with the famous error:
error '8004020f'
/sendEmail.asp, line 139
I have researched all around the internet, and I see many have issues with this error, but not the kind that I am having, in which few emails are send and then it stops.
Also, all emails are being sent to the same domain, the official school email of the students.
Any ideas? Any settings that I might want to ask the website hosting guy to change?
Here is the code.
Dim objMail
Set objMail = CreateObject("CDO.Message")
objMail.From= "someEmail"
objMail.To=rstemp("Email")
objMail.Cc = "someEmail"
objMail.Subject = subjecttext
objMail.HTMLBody=tempData
objMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusing")= 2
'Name or IP of remote SMTP server
objMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserver")="smtp.*"
'Server port
objMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserverport")=25
objMail.Configuration.Fields.Update
objMail.Send
set objMail=nothing
tempData = nothing
EDIT: On more debugging, it turns out that when I replace the objMail.To from sending it to each student's email to my own email. It works fine and sends all the emails to me.
Please check first all the Emails is valid and no test email is there. and you can test it with send all emails on same email address for no. of time and can track the problem that is this Email address problem or something else.
