Did you reload the configuration? ("fail2ban-client reload")
What action are you using - you mention ipset, are you using iptables-
ipset-proto4? I don't know anything about ipset, but can you see what
ports are being blocked in the fail2ban-dovecot set (just to make sure
it is doing the correct thing).
If you manually add an IP address to the *exim* jail, does it get
blocked?
P.
