Hey, guys I'm stuck with postfix. It cannot send emails and I cannot find out why! smtpPort 25/tcp is open. I can telnet localhost with 25, but not the localhosts IP(192.168.1.15). Sendmail is OFF. Here is the main.cf file!

Find out what was running on port 25 and shut it down.
What is the output from
Kind regards

My, my, my! This is so funny - hahhaha
I don't know how that happened but:

1. I was missing postfix as app but had the deamon
2. I've stopped sendmail but it had continued working on 25/tcp
3. Somehow I was missing /etc/mail/accesses.db as it comes with sendmail

I had to reinstall both sendmail and postfix and then stop sendmail on all levels - it worked out! I can now send emails!
Thanks!
