[bug] Syntax error in Postfix configuration

usrAsd32
Hello,

when UTM is configured to use an external SMTP-server with encryption and authentication (Management -> Notification -> Advanced) enabled, there might be a problem with the generated Postfix configuration:

If the chosen SMTP-Server is a DNS-Host, [FONT="Lucida Console"]/etc/postfix/main.cf[/FONT] contains the following line (which is correct): 
relayhost = [dns.of.mail.server]:587


And [FONT="Lucida Console"]/etc/postfix/clientauth[/FONT] contains its entry in the following form: 
dns.of.mail.server     username[:P]assword

But this is not correct. According to [1], the syntax has to be 
[dns.of.mail.server]    username[:P]assword


In my case, changing this line, running postmap on [FONT="Lucida Console"]/etc/postfix/clientauth[/FONT] and reloading Postfix did solve the issue not being able to send/get notification mails.

The permissions of [FONT="Lucida Console"]/etc/postfix/clientauth[/FONT] generated by UTM are 644. 600 should be sufficient.

I'm running UTM v9.209-8.

Regards,
Gregor

    If you have a paid license, you'll want to open up a support case, so you can inform Sophos about the issue (this is a user to user forum).  If this is a free home license, your only way of notifying Sophos would be to try this on the 9.3 beta and if the issue persists, report in the beta forum.  https://www.astaro.org/beta-versions/utm-9-3-beta/.  The later is the best way to get the bug "known" and fixed, as in the beta forum developers monitor the threads directly.

    Before I've written in this forum, I've tried to file this bug under [1], but it hasn't been worked as I'm using the Home licence: According to [1], I've standard support, so I have to contact my local certified Sophos partner, which I don't have.

    But I'm sure this information will sometimes reach Sophos. Either here are reading some enthusiastic Sophos employees, or one of their business clients is suffering the same issue.

    Regards,
    Gregor
