How to Setup SMTP Service?

Hello everyone, when i was running cPanel there was some information about SMTP for email service (auto configured?) I could use it at port 465 or wtv with my email as login and email password.

But now with webmin / virtualmin i just don't know where to look for this.

Is there any guide how to Setup forwarding / sending email with SMTP Service?

I can't send emails with SMTP at my IPBoard Forum, it's giving me error: IPS\Email\Outgoing\Exception: 535 5.7.8 Error: authentication failed: authentication failure (535)



Project: ยป Webmin Core

I'm a bit confused - are you asking how to configure Virtualmin to send email?

Howdy -- it sounds like you're receiving an authentication error there.

There's two things I'd suggest.

One, you may want to take a peek at /var/log/mail.log and /var/log/auth.log, to see if there's any more descriptive errors associated with that message.

And two, I'd suggest double-checking what username you're using there. You'd want to ensure it's the correct username for the account.

You can verify what username it's expecting by going into Edit Users, and in the "Login" column it shows the username.

I've configured my mail server but im getting this errors under mail logs:

From IP Board Forum: postfix/submission/smtpd[18420]: lost connection after UNKNOWN From Hotmail: postfix/smtpd[18182]: NOQUEUE: reject: RCPT from ...... Relay access denied; proto=ESMTP

The error there suggests that Postfix doesn't think it's hosting email for the domain in question.

You may want to verify that the "Mail for Domain" feature is enabled for this particular domain.

forum is trying to use the SMTP service from his main domain. Forum domain is: Main domain is:

Hmm, are you able to send email from other web apps?

For example, what it you were to install the RoundCube Install Script.

If you log into RoundCube as one of your email users, can you send an email via it?
