[Dovecot] Re: Rogue child imap processes when using Mac imap clients

[darren david]

hey all-

just a ping to see if this ssue has been resolved. it's still popping up 
for me. Also wondering whose the owner of the OpenBSD port and if we'll 
be seeing an updated version anytime soon? we're still on 0.99.10.2 as 
far as i can tell...

cheers,
darren
