How to test sendmail?

ericchaves · Post by **ericchaves** » Fri Jan 01, 2010 11:55 pm

Hi FOlks,

After installing the OpenEMM server, I created a mailing and send message to administrator recipient. OpenEMM page says everything is ok and messages was created but I never receive them.

So I was wondering:

1- Is there a way to test the sendmail installation without using openemm?
2- Which log files could I check in order to see what went wrong?

Thanks again for all the help and support.

Best regards,

/var/log/mail
or similar should tell you, what happened, whether email was delivered or not.

Hi Pheelix,

From the logs it seems that connections are being deferred:

Code: Select all

Jan  2 13:30:11 emm sendmail[6722]: o02FU847006722: to=myemail@hotmail.com, ctladdr=eric (1000/1001), delay=00:00:03, xdelay=00:00:00, mailer=relay, pri=30006, relay=emm.XXX.com.br. [XXX.XXX.XXX.XXX], dsn=4.0.0, stat=Deferred: Connection refused by emm.XXX.com.br.

I'm also trying to issue a test from command line with "sendmail -v myemail@..." with the same deffered connection status.

Also, when I execute netstat -nl I don't see anything listening at port 25.

Do you guys have any idea on what could be wrong on my configuration?

Finally, apart from that I'm seeing the following message at maillog:

Should I change permissions on file?

Thanks in advance.

Ok, found the error so far, and registering it here for future reference.

The problem was related to bav.socket error, which was caused because smctrl was not running setuid, as explained in http://www.openemm.org/forums/ftopic56.html

Code: Select all

chown -R openemm:openemm .bash* *
chown root:root bin/smctrl
chown root:root conf/bav/bav.rc
chmod 6755 bin/smctrl
chmod 0600 conf/bav/bav.rc

Also needed to install libxml2, which was not installed in my ubuntu by default.

After that everything seems to be is working like a charm.

Thanks for the tip!

@OpenEMM Team:

Code: Select all

chown -R openemm:openemm .bash* *
chown root:root bin/smctrl
chown root:root conf/bav/bav.rc
chmod 6755 bin/smctrl
chmod 0600 conf/bav/bav.rc

Why is this not included in the current install guide of OpenEMM 6.1?

Because it is not necessary if you use option "p" for unpacking the tarball (see extra note in chapter 5, 2nd paragraph).

Argh.
