postfix wont stay running

On the webmin ‘system information’ tab, I click the play button next to post fix and it starts, and I get the red stop and the reload icons, but about 5 secconds later when I press F5 or refresh the page it is stopped again.

I dont know how to begin to diagnose the problem.

Can you help.

If Postfix fails, there’s probably going to be an error listed in the email log – either /var/log/maillog or /var/log/mail.log, depending on your distribution.
-Eric

There is a guide called "Troubleshooting Common Problems" in the documentation that will give you several pointers on…common problems. :wink:

And, if it doesn’t have answers, then we’ll definitely need to see logs, as Eric mentioned.

im reading it, I try to help my self as much as possible and not bother fourm people but because I am using fedora 9 I cannot use a install script and am have a ‘fun time’ now… Weeeeeeeeeeeee …

Here is log:

seems like sendmail is already running, hence why postfix cant run. it wants port 25 but it has been taken.

you need to switch MTA from sendmail to postfix.

To display which MTA alternative is in use:

# alternatives --display mta

To choose from the available MTA alternatives from the command line :

# alternatives --config mta

To setup Postfix as the default mail system:

# alternatives --set mta

ronald’s got you (mostly) covered. You’ll also need to stop sendmail:

service sendmail stop
chkconfig --level 345 sendmail off
service postfix start
chkconfig --level 345 postfix on

You could also do all of this in Webmin, in the Bootup and Shutdown module, if you prefer.
