[solved] SASL error on MailServer-Setup

[Gamerboy59]

Hello,

I'm currently experiencing some issues on my mailserver setup. It seems like there's a mistake in configuration but I can't figure out which part sucks. I get the following error message:

Jul 22 14:58:15 server postfix/smtpd[16170]: warning: SASL: Connect to private/auth failed: No such file or directory
Jul 22 14:58:15 server postfix/smtpd[16170]: fatal: no SASL authentication mechanisms
Jul 22 14:58:16 server postfix/master[15928]: warning: process /usr/lib/postfix/smtpd pid 16170 exit status 1
Jul 22 14:58:16 server postfix/master[15928]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling

How to fix it?

 

 

Thanks for your help.

No solution?

[d00p]

Sorry i'm not responding ASAP...some people may have a life and work to do...

 

Just re-check that you have used the froxlor config-templates 100% and restart all services. Because your postfix configs do not look like the ones we provide.

[Gamerboy59]

It it looks like it's dovecot which causes the issues.. on Ubuntu there's no longer the postfix-dovecot package, so maybe this is missing. idk

 

 

Edit: Config is correct.

[Sephiroth]

check manually if the auth socket is available after starting dovecot and the permissions are correct. Check your dovecot configuration. Disable chroot of you smtp transport (master.cf)

[Gamerboy59]

The socket is unavailable. However, when I use default config it is available.

 

When will you have added configs for Ubuntu 14 (ETA)?

[d00p]

Just take the ones for Ubuntu 12.04 - they should do (at least way better then no froxlor config at all, because this won't work!)

[Gamerboy59]

I did, however this causes such errors.

[d00p]

Well the ones you've posted are NOT the froxlor-configs...did you update them with the templates froxlor shows you? If so, what are the recent error messages?

[Gamerboy59]

This are definitely the configs generated by froxlor, thus the errors stay same.

 

EDIT: I reinstalled the server. Hopefully it's now working. Seems like there was a general mistake in mailserver default setup.
