Smtp sent email either never sends or takes forever

I’m not sure what’s going on or where to look but it seems that mail is either taking forever to send or not at all anymore.

Have a look in /var/logs/mail.log.

It is also possible to get more log detail … in /etc/postfix/ find these lines and add the -v to the end, then do sudo postfix reload.

    smtp      inet  n       -       y       -       -       smtpd -v
    submission inet n       -       -       -       -       smtpd -v

(This logs a lot more detail. Multiple -v options make the software increasingly verbose, start with just one -v. You probably want to remove the -v’s when you’ve sorted things out.)


I think a lot of how I’m using this is likely my fault in this case I’m going to consider this closed for now. That log file tells me a lot of useful stuff I wish I had it earlier.
