Title: [SOLVED]Problem with smarthost
Post by: doctor_house on January 06, 2013, 11:49:47 am

Hello everyone, i am pretty new to this distribution but i find it quite nicely done. Although i have a problem with my smarthost. I am running this distro at my workplace and we are having issues with our smtp relay.
The message queue reports:
SASL authentication failed; cannot authenticate to server mail2.example.com[xxx.yyy.zzz.aaa]: no mechanism available
There is the option to change the auth method from plain to login but no matter what i choose the error remains the same.
Would you kindly provide some help please?

Regards.
Giulio

Sorry for not being more clever but I don't understand if your issue is between Zentyal server and smarthost or between mail clients and Zentyal server.
I suppose this is between Zentyal and smarthost but don't understand why any authentication mechanism would be mandatory between MTAs.

thanks for replying. My explaination is probably unclear.
I am using Zentyal server to try to send my mail through an external smarthost. In order to be able to use this smarthost i have to use authentication. The problem is that even if i put the correct username and password in the smarthost configuration my mails don't get through it because of this error:
SASL authentication failed; cannot authenticate to server mail2.example.com[xxx.yyy.zzz.aaa]: no mechanism available

i have read a bunch of articles about postfix auth mechanisms but i am not very experienced at using linux based servers so i was looking for your support in this case. It's probably something harder to axplain rather than to solve.

Again thank you.
Giulio

My Zentyal 3.0 test platform is not running anymore.
Could you please check on your that cyrus-sasl2 package is installed ?

Could you also post here your main.cf conf file, at least part related to smtp_sasl ?

That was the right hint and after a little bit i did it!! Thank you.
In case somebody runs into the same issue my problem was that the package libsasl2-modules was not installed. Installing it solved my problem. Thanks for the help.
