Good evening. I'm setting up my first mail servers and have got
opensmtpd working correctly and am now looking at options for pop /
imap servers. 

Does anyone know of any resources (other than the manual) for getting
started? Maybe some presentations or blog posts, that sort of thing...
or some sample conf files. 

Also, how do they perform compared with the likes of Dovecot? 

Thanks for any tips.
