just setting a new Dovecot server to migrate from older system, but, I have a general question:
1. I've set the server with self issued cert, and both pop/imap StartTLS/110/143 SSL/993/995 (apologies if I'm using wrong naming terminology) is there a 'preferred way'? should I tell users to use 143 over 993 ? or 993 over 143? or? my current understanding is that some (MS?) clients might not support StartTLS/143 ? so best to offer both ? I think? some public WiFi block 993/995 but allow 143/110, hence, another advantage for using 143/110 thanks for any advice, V
