Postfix TLS Library Problem No such file

Server
21

For anyone that has the same problem, here is how I solved the warning. Still I am unable to send mail from my server to a specific endpoint, perhaps my IP is blocked I don’t know.

To fix the warning for the path using Ubuntu 18.10 I modified two files:

/etc/postfix/main.cf
smtpd_milters = inet:localhost:8892
non_smtpd_milters = inet:localhost:8892

/etc/opendkim.conf
Socket inet:8892@localhost

You’ll have to restart opendkim and postfix
sudo systemctl restart opendkim
sudo systemctl restart postfix

** How to Check if opendkim is running and on what port **
sudo lsof -i

This should show you a line like this:
opendkim 960 opendkim 3u IPv4 20033 0t0 TCP localhost:8892 (LISTEN)

I’ll post back if I ever find the answer to my problem, but at least now there are no errors or warnings in my log files. Thanks for all who attemtped to help me.

Woohoo!

The issue was with my IP. Once I changed IP’s everything worked. So ya, it was a blacklist problem.

P.S. so you guys know, Yahoo.com rejected mails from me after I changed my IP even though I’m not on their blacklist server, but I don’t think my dns changes had time to propagate.
