Email accounts with wrong SMTP User?

Hi all,

Iā€™m really confused about the email configuration, maybe someone can clear up things. Thanks a lot for your help!

I have installed suitecrm on a dedicated machine, but my Email server is a froxlor managed second machine. All email accounts are running fine on other clients. While installing suitecrm, I have setup the ā€œEmail settingsā€, now under Admin->Email settings. Here I have given an account:

notification@mydomain.com

Now I have installed a group email with automated case creation, and receiving / case creation works fine. But the automated answer is blocked by the outgoing mail server. The group email adress is:

support@mydomain.com

Now, when receiving a new mail, a case is created and an email is sent. In the logfile of the emailserver is this:

Mar  3 15:46:04 froxlor postfix/smtpd[23898]: NOQUEUE: reject: RCPT from unknown[xxx.xxx.xxx.xxx]: 553 5.7.1 <support@mydomain.com>: Sender address rejected: not owned by user notification@mydomain.com; from=<support@mydomain.net> to=<test.customer@live.de> proto=ESMTP helo=<xxx.xxx.xxx.xxx>

It seems that suitecrm tries to send always with the same SMTP-user (in this case notification@mydomain.com) instead of the given one in the group email account (support@mydomain.com)

Same is on replying an email with the group mail account. Sending is not possible, because the user ā€œnotificationā€¦ā€ has no rights to sendā€¦

It is right that you have always to send with the same SMTP-user?

Best regards,
Sebastian
