I'm using postfix to send server notifications to another mail server who encrypt the content of the email with CipherMail (PGP). The second mail server forwarding the email to me.
I would like to modify the subject line in dependency of message body before the email sended to Server B.
Example:
If the email contain "Found an error", the subject should be change in "[Server A] Error".
If the email doesn't contain "Found an error", the subject should be change in "[Server A] Status".
Background: Before I installed CipherMail, I sorted my emails by content. Of course this doesn't work anymore with PGP encryption.
Anybody got an idea for that?

I am having issues with mail bouncing when sending from my own server to my own active yahoo account using JavaMail. The mails are passing SPF, DKIM and DMARC according to google mail that receives the same messages being bounced by yahoo. I can send messages from other accounts to my yahoo account without issue.
The messages send fine from my server to ZMail, GMail, Microsoft mail. Looking at the emails, the only thing that I have noticed is the message header for the Message-Id. My messages have the following header:
Message-ID: <923936395.17.1634776639078#[internally visible hostname]>
I am wondering if this header could be the problem and whether there is a way in JavaMail or in the Apache James to set the hostname or IP address that gets used in this message so that rather than using the "internally visible hostname", I can get the hostname that is externally visible. I have been searching the available documentation for Apache James and JavaMail but have not found any parameters to try in order to resolve this.
According to the Decompiled SRC of sun mail it should be possible by setting some properties for your session.
props.setProperty("mail.from", user);
props.setProperty("mail.host", host);
//props.setProperty("mail.user", user);
The Id will be updated by the save method (saveChanges()) and will trigger an new ID generation (updateHeaders() -> updateMessageID()). (Looked up in the decompiled MimeMessage.class)
Leading to the HostPart called in javax.mail.internet.InternetAddress.
The relevant method is _getLocalAddress.
Here you can see that the values get extracted from the Properties or will fallback to your local machine.
Used Fields:
user.name
mail.from
mail.user
mail.host
The user.name property can also be looked up from the system props.
EDIT: I found a solution. You can find it here. I had to resort to using mailR. I could never get sendmailR to work with the Office 365 services.
I am trying to send a single email using library(sendmailR) to later send daily automated emails to about 500 people. Unfortunately, I'm suck in step 1.
It is vital that I send these emails from my institution's Outlook account. I have no idea what control settings to use in order to successfully send mails from Outlook. I checked a couple of questions but they are either using the gmail SMPT server or they do not specify the control = ... settings they used. For example:
Use sendmailR with Windows
Sending an email from R
This is what I'm working with:
from <- "<myaccount#institution.org>"
to <- "<boss#institution.org>"
subject <- "Hello from R"
body <- list("It's working.")
sendmail(from, to, subject, body,
control = list(smptServer = "oultook.office.365", port = 443))
And I'm getting the following error message:
Error in wait_for(code) :
SMTP Error: 5.7.57 SMTP; Client was not authenticated to send anonymous mail
during MAIL FROM [SN4PR0501CA0061.namprd05.prod.outlook.com]
I believe I'm not specifying the port correctly. The sendmaiLR documentation is not specific enough, but something tells me I should be writing the port as "port 443"or something along those lines.
Does anyone know what controlsettings I should be using?
I am getting 555 syntax error in mailfrom
SendData(tcpSocket, string.Format("MAIL From: {0}\r\n", MailFrom));
if (!CheckResponse(tcpSocket, 220))
{
tcpSocket.Close();
return false;
}
is it the problem in my local system because of localhost?
Please help me. I am using this code from below link.
http://www.codeproject.com/Articles/5189/End-to-end-Email-Address-Verification-for-Applicat
Please don't try to implement your own SMTP client, use the one that comes with .NET: System.Net.Mail.SmtpClient.
Many SMTP servers require TLS, for example, which your code does not account for.
Furthermore, for security reasons most mailservers will not reveal if an email address in an RCPT TO line is valid or not. If a system can positively reveal an address exists then it can be used by spam harvesters. Consequently using a dry-run of an SMTP client should only be used to validate an email address (because of the complicated rules regarding valid email addresses). The verification (a separate concept from validation) must be performed manually by requiring the user to respond to an email sent to that address, there is no other way to be sure.
I am sending account activation email from my .net app.
I set the from address to "xyz.support#gmail.com" and from name "xyz" where xyz is the name of the domain i.e. our website.
It was not a problem when we were using Google's SMTP server as I provided credentials to google during sending. But now I am using my own web server's SMTP to send the email.
When I view the activation email in gmail, I get this:
This message may not have been sent by: xyz.support#gmail.com Learn more Report phishing
Is there a way to get rid of this so that gmail and other client don't show this message?
Here is the code:
var smtpClient = new SmtpClient();
var message = new MailMessage();
smtpClient.Host = _config.SMTPServer;
message.From = new MailAddress("xyz.support#gmail.com", "xyz");
message.To.Add("newuser#gmail.com");
message.IsBodyHtml = true;
message.Subject = "Test subject";
message.Body = "Test Body";
smtpClient.Send(message);
Thanks
The domain of the FROM address has to match the domain of the SMTP server that is sending the email, otherwise your message is treated as as spam.
This explains why you avoid the "error" by sending via Google's SMTP server.
The suggestion by IrishChieftain to use SPF helped me, so here is a summary of the steps I did:
1.) First, I also received emails in my GMail inbox that I sent from my sever and that got the "This message may not have been sent by..." warning.
2.) Next, I looked at the source of the email inside GMail (clicke the arrow next to the message and select "Display original"). An excerpt from there was:
Received-SPF: fail (google.com: domain of me#mydomain.com does not
designate 211.113.37.19 as permitted sender) client-ip=211.113.37.19;
So Google directly told me what to do: Add some SPF records in the DNS of my domain "mydomain.com" to get rid of this warning.
3.) Therefore I logged into the control panel of my DNS provider and added two TXT records, something like this:
*.mydomain.com. 180 v=spf1 +a +mx ip4:211.113.37.19 -all
mydomain.com. 180 v=spf1 +a +mx ip4:211.113.37.19 -all
Please note that I entered each line in three separate fields:
One field for *.mydomain.com.
One field for 180 (the TTL, 3 minutes in my example)
One field for v=spf1 +a +mx ip4:211.113.37.19 -all
4.) After that, I waited some time and tried to resend. This succeeded. Google now shows in the original:
Received-SPF: pass (google.com: domain of Received-SPF: pass (google.com: domain of me#mydomain.com designates 211.113.37.19 as permitted sender) client-ip=211.113.37.19;
Please note that I choose the SPF version since the mail server is on a different machine as the web server, so I could not perform the other solution as Mulmot wrote.
There is also an SPF Wizard from Microsoft to correctly generate SPF records. Alternatively, here is yet another SPF generator.
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.
