OpenEMM Technical Support Forum

Hi,

I'm trying to configure OpenEMM on my home server. Everything is installed, I can set up mailing and send it. OpenEMM says, that mailing was sent, but messages are not delivered. I found that in Sendmail log:

Feb 12 23:12:13 openemm sendmail[3000]: 2229T5b8200000001: to=<mikolus@mydomain.com>, delay=03:38:04, xdelay=00:00:00, mailer=esmtp, pri=6030000, relay=mydomain.com., dsn=4.0.0, stat=Deferred: Connection timed out with mydomain.com.

My server is behind a router, all ports are redirected. I added "A" record on my dns to point openemm.mydomain.com to my ip address. I can connect to the panel using openemm.mydomain.com:8080. I also added MX record with "openemm.mydomain.com" as the value. The problem is, that there is only one mailing receipient and it's not mikolus@mydomain.com and I didn't set mydomain.com as the relay for sendmail.
My OS is Fedora 14 and I'm using OpenEMM 6.2.
Does anybody know what's going on?

Actually, it was my fault. I set the wrong sender email address during the installation, changing the sender hostname in the db fixed that problem (it's the "Initialize/Update the MySQL Database" section of the wiki).

Just for info: The wiki content is written and modified by OpenEMM users. The OpenEMM Install Guide and the OpenEMM User Manual are the "official" documents.

Most ISP's intentionally block the mail port (25) to keep users from hosting their own mail servers.
The "connection timed out" error is along those lines.
