my application needs to send out emails to its users, but somehow I can't make it work. I have installed the SMTP server and in IIS I have set SMTP to use localhost, with port 25 without authentication. But when I try to send email, I am allways getting error
No connection could be made because the target machine actively refused it 127.0.0.1:25
When I choose the option to store email in directory, it works fine, so the problem isn't in my app. Why does this happen? The only thing I am thinking about, is if I need to have port 25 opened or not?
This would happen if you don't have an SMTP server listening on port 25.

I have tried setting up SMTP in the dotenv file:
MAILER_URL=smtp://mydomain.nl:25?encryption=tls&username=noreply%mydomain.nl&password=***`
And I've sent an email using php bin/console swiftmailer:email:send. This gave me an error:
[app] Exception occurred while flushing email queue: Connection could not be established with host webmail.mydomain.nl [Connection timed out #110]`
So I assumed this is caused by the firewall. So then I tried to send an email via an online SMTP tester and the email got sent and all worked as expected.
However, this still does not work on my server. Even after turning off the firewall on my (Windows) VPS, the same error persists.
My setup is as follows:
I have a VPS (WINDOWS) with plesk where I host my domain and the mail server.
I also have a home server (CENTOS) where I host my subdomain with plesk.
What am I overlooking? What could be the cause of this issue?
Some host providers block 465 and 25 port. So only 587 is left to use. First, contact your host provider and ask if they are blocking SMTP ports. And if not please come back with more information and server config.
So apparently, please correct me if im wrong. This is what I think I did wrong:
I have a subdomain from my main plesk which I host on my home server. The project i'm working on is running from there.
The main domain with that plesk account is running on a VPS with the mailserver.
As it turns out (I think) my ISP from my home internet has restricted access to port 25. And thats why my home server cant access the mail server.
I tried to disable firewalls everywhere, even routed the ports in my router to my home server, nil fix. (please note that i tried to telnet to several SMTP servers not just my own) with all access rejected.
I tried it with another port (465) from my home server and it works now.
At the end using another port did the trick. I am however not sure that this is the issue. But this is just my guess.
I have got a simple BizTalk Application in which there is only one schema and pipeline. I have simply add XML Validator in validate stage of pipeline.I have deployed this app in BizTalk Server 2010.
Now I have created a receive location which takes a XML file and set its receive pipeline which i have created. I have also marked "Enable routing for failed messaged" in receive port.
I have also created a SMTP send port and and configured it with mail server name and etc.
Receive port is working fine but send port is unable to send emails.
When i check "Track Service Instance" is shows an error "Transport failed to connect to the server".
Update: I am using Gmail SMTP server name in order to send e-mails and I am getting the error "The server rejected the sender address. The server response was: 530 5.7.0 Must issue a STARTTLS command first. ye1sm22267001pab.19 - gsmtp"
Where could be the problem? Any help will be appreciated
With that error in your update the problem is clear.
The Gmail server is expecting a SSL connection.
See SMTP TLS problem
The standard SMTP adapter does not support SSL/TLS connections.
You will need to write a custom adapter or purchase a third party
adapter to support SSL connections

Greg.Forsythe
EDIT: An alternative is to connect to a local SMTP server that doesn't require SSL/TLS and let it route the e-mails.
Are you running 32 bit or 64 bit? Is your tracking host in 32 bit or 64 bit? MIME/SMIME encoder pipeline can't run in 64 bit mode... are you using that?
http://msdn.microsoft.com/en-us/library/gg634591.aspx
"Transport failed to connect to the server"
This error message basically means the BizTalk SMTP adapter is unable to connect to the SMTP server or the server does not allow to send the e-mail.
Try connecting to the SMTP server with the telnet client (you may need to install this as an additional feature) or by configuring the proxy (available on the SMTP adapter and adapter defaults).
It might also be the case that you need to authenticate towards the SMTP server.
Also, some SMTP servers do not allow to send an e-mail from an unknown domain like "someone#notthenameofthecompany.com".
Hope this helps.
I have a situation where a 2008 server with IIS7 has been application level compromised and is sending spam from port 25. We have ran a virus scan and removed the infected files yet the spam is still being sent.
We know the spam is coming from a local file as the firewall has port 25 blocked inbound and the SMTP log is showing all requests appearing from the local server. We have ran a LogParser scan of the sites (which there are many) for any POST data to files on the server but the results all look genuine. The PID sending the data on port 25 is simply inetinfo.exe so this isn't much use either.
I would like to identify what file is sending this e-mail, can anyone think of a way to do this?
Have you shut down the smtp server under properties for local outbound? meaning 127. etc...? also, have you looked in the que folder under inetpub to see if the offending message is in there? In some cases a file can change the remote server on smtp in IIS to send via aproxy or some other service so it would ignore your scans.
in addition, not all mail has to use port 25 to send emails. it can hit any port if the creator tells it to.
I am creating a banking application in asp.net v 2.0.I need to send confirmation email when a user creates the new account.
I am running the application in localhost.DO I need any special rights to send SMTP email?
provide me a proper way to send email from my application.

Do you have a SMTP server set up on localhost? Test by using telnet on the server:
telnet 127.0.0.1 25
If the server responds, try sending raw SMTP commands to send an email and trouble-shoot from there.
I find the easiest way with the Microsoft SMTP server is to disable any checks for authentication and rely on relay restrictions, then restrict relaying to 127.0.0.1.
The fact that you're running on localhost shouldn't make any difference.
As long as you have valid email server settings, and it's allowed on the system you are running on, this works just fine.
Did you try it? Did you have a problem?
I think you can sent by gmail smtp server. check this out

I'm having trouble setting up SMTP to relay through a 3rd party server.
I'm new to Server 2008 so please bear with me.
I have found the SMTP server in IIS6 which is currently off, but is there one I need to use in IIS7? (IIS7 websites do have the SMTP icon so that 'role' must be installed).
I have used the IIS7 icon to set the remote name and credentials. Using a little test website to send an email to my hotmail account, it comes up saying
Mailbox unavailable. The server response was: 5.7.1 ... we do not relay
or occassionally it says
The remote name could not be resolved: 'The SMTP URL'
I can send using localhost but because that is effectivly spoofing the "from address" loads of them get bounced back!
Anyone got any ideas????
Don't worry, it turns out the people in control of the relay server gave us the wrong username and password, so it would never have worked!
Also, didn't need SMTP server in IIS6 either, so will remove it.
Good to hear you got it sorted. For posterity's sake, if you need to run a SMTP service in IIS7, you need to install the IIS6 "bits" which includes the IIS SMTP service.
One fun gotcha--service gets installed as a manual start for some reason, that was fun to troubleshoot at 3am after the 7th tequila shot.
