Just set up a new server with Virtualmin on CentOS 7, and ran into lots of problems... I think it's related to this new install script, perhaps version 6 of VM.
SASL auth keeps failing, can't send or receive emails at all. I spent 2 days trying to configure, and kinda gave up.
Same issue on my part also,Since 2 days no work its smtp doesnot work at all,New update is just killing us.
Is yours a fresh install of Virtualmin 6, or is it an existing installation that was updated to the Virtualmin 6 module (but nothing else changed). As far as I know, nothing would have changed in the mail configuration if you updated an existing installation. We'll get it fixed, whatever it is, but right now I have no idea where the problem is; I'm hearing multiple descriptions of things that sound like completely unrelated problems (and may be completely unrelated problems). ;-)

Just to update on the "update is causing it" theory: it's not the update. ;-)
OP has a misconfiguration of myorigin in Postfix, probably caused by not having a fully qualified domain name set when /etc/mailname was set (it gets set to the system hostname when mail servers are installed, AFAIK). It's a debian/ubuntu quirk that I've never been very fond of.

What appears in the maillog or mail.log when you try to send mail to the server?
And, what specifically is the bounce message received by the sender?

Here's the problem:
name not found. Name service error for name=server type=AAAA: Host not foundIt can be caused by one of a few things:
So, check your hostname:
# hostname -fCheck to be sure that name can be resolved (using
host hostname, where "hostname" is whatever the hostname command above returned as the name of your server).And, make myorigin match that (or match something that resolves to your server IP address). I usually leave myorigin at the default, but Debian/Ubuntu likes to make things complicated (and prone to failures like this). The default is
$myhostnameand is sensible for most deployments that only have one mail server receiving mail.--

ubuntu 16.04 here. i suspect the issue is with the recent clam update. ive got a mail.log full of "CLAMAV: couldn't connect to: /var/run/clamav/clamd.ctl: no such file or directory"
a simple reboot seems to have fixed the issue. ha! kinda forgot about that trick since i left windows behind.
Problem solved, it was the FQDN configuration that was lost when rebooting the system.
Yeah, if your system is not on a static IP and uses DHCP to configure the network, you have to take some extra steps to ensure hostname, name servers, etc. remains the same across boots, or you'll find you have a number of problems.
