Still present in 18.04LTS. For instance the first postfix jail filter rule catching RBL blacklisted intruders:

^%(__prefix_line)sNOQUEUE: reject: RCPT from \S+\[<HOST>\]: 554 5\.7\.1 .*$

It simply does not appear in mail.warn making the rule basically useless.

I will repost this on https://github.com/fail2ban/fail2ban/issues
