Sendmail/Procmail queue

27.04.2005

Sendmail or Procmail?

Procmail is mail processing daemon which by default use Sendmail to deliver messages. If you have problems with delivering messages using SMTP protocol, you propably have problem with Sendmail.

How Can I locate problems?

It is very easy to find out problems, you can easily check /var/log/maillog (default location in Fedora) by typying this:

tail /var/log/maillog

I have resolved problem

After resolving problem you propably need to send immediately all messages in queue. Before do this I recomend to check messages in queue first.

sendmail -bp

You will propably get output like this

-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
947797EC3     60517 Tue Apr 26 13:44:19  ****@****.cz
           (connect to relay.****.net[206.**.**.**]: Connection timed out)
                                         ********@*********.net

Now you can send all messages to queue without waitning for long period.

sendmail -q -v

Congratulations, you have resolved problem and now employees can work again.
