Can't connect via smtp

Help! (Home for newbies)

Hi,

I have a trouble with the smtp connection. When I try to connect using GMail (add external account option) with the following data:

  • SMTP: mail.domain.com
  • Port: 587
  • Username: username
  • Password: password
  • Connect using TLS

I get the following error:

“535 5.7.8 Error: authentication failed: generic failure code(535)”.

Here is my mail log:

Is the third fresh install of virtualmin trying to fix this issue. Thanks for any help!

This was an old message caught up in the moderation queue, so not sure if it’s still relevant, but the issue can be resolved by running:

# virtualmin config-system --include SASL

The SASL configuration was incorrect on some distros/versions for a while after the move to the Virtualmin 6 installer, and this fixes it.
