we recently moved to Zimbra, version Release 7.2.0_GA_2669.RHEL5_20120410001958 CentOS5 NETWORK edition.
Sending emails from the web interface works ok, as well as when using Outlook connector+Outlook. However, when I try using sendEmail.exe (on windows) or sendmail/swaks on Linux in order to get notifications, I get the aforementioned error.
This is the log output I got from swaks:
In our setup, there are no relays. I'm mentioning this, as I searched the web, and only docs mentioning this problem are:
[root@somemachine tmp]# ./swaks --server mail.example.com --to email@example.com --from firstname.lastname@example.org --auth PLAIN --auth-user email@example.com
=== Trying mail.example.com:25...

[SOLVED] multiple accounts on smtp relay
and the wiki article:
Outgoing SMTP Authentication - Zimbra :: Wiki
for which I don't see how to apply in our case.
Can someone point me in the right direction? Where should I look? What may be the problem here?
