Package: fail2ban Version: 0.9.6-1 Severity: normal Dear Maintainer, There is an issue when enabling postfix-sasl jail in fail2ban. When there are multiple failed login attempts fail2ban executes following command: iptables -w -I INPUT -p tcp -m multiport --dports smtp,465,submission,imap3,imaps,pop3,pop3s -j f2b-postfix-sasl Unfortunaltely in debian /etc/services does not contain imap3 service anymore which causes fail2ban to fail with this error: iptables v1.6.0: invalid port/service `imap3' specified
This is not an issue with fail2ban itself, but rather netbase. Not sure why in latest 5.4 version of the package imap3 was removed.
