Sendmail [25: Connection refused] fix

If you can't receive email from the outside and got next error:

 (Delivery Status Notification [(0) www.domainname.com. [1.1.1.1]:25: Connection refused]).

You should check the iptables , is port listening .

if you can telnet on port 25 from localhost and can't from remote you need to modify your sendmail.cf file. Just comment the next line:

# O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA

 

Save config and restart sendmail.
