SendMail problem after the latest upgrade

My server is running RedHat Linux 8. Today I installed sendmail update as it is available from redhat up2date agent. After the installation, I could not send any mail outside. I can receive incoming mail. I found this in the maillog entry:
relay=[], dsn=4.0.0, stat=Deferred: Connection refused by []

Before the update my ip address is displayed instead of After the update for some reason it is showing up as and so mail is not going out. I thoroughly checked nameserver configuration and network configurations. Everything looks fine. I still don't understand why it is trying to relay thru after the update.

Appreciate any help.

Thanks !

Try posting your sendmail.mc so we can see what are the options you're using in sendmail.cf.

Also, that entry shows up in your mail server or in your workstation ?.

Try doing netstat -an | grep LISTEN | grep 25
and see if you get something like:

tcp        0      0*   LISTEN  

You're probably being able to receive mails because sendmail is listening in the eth connected to Internet, but it's not listening to requests on localhost.

I thought this might be a bug and sent a mail to sendmail.org. They responded saying that this is not a bug and that I should modify submit.cf. I did and it works again !
