saslauthd service: disable it or not?


I have a virtualmin server properly configured and working.

Then I installed Roudcube for one of the domains in the server, but I noticed that it was impossible to send e-mails because I stopped the saslauthd service (recommended by Config Server Security Firewall - CSF).

After manually starting saslauthd I was able to send e-mails via Roudcube. So, this is the only way to send e-mails via smtp/Roundcube in Virtualmin?

Does it poses a security threat to my server?

Thank you!


The saslauthd service is used to perform outgoing email authentication with Postfix. If you’re using your server as an email server, you would want to have that service enabled.
