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?
I believe the recommended way for years has been to use the
encrypted/SSL versions of both IMAP and POP3 - so ports 993 and 995
respectively. Otherwise you are effectively sending data in plain text
over the internet.
my current understanding is that some (MS?) clients might not support
StartTLS/143 ? so best to offer both ?
As far as I know, all popular email clients of the last 15 years, that I
can think of, support POP3 on 995 and IMAP on 993 with SSL.
I think? some public WiFi block 993/995 but allow 143/110, hence, another
advantage for using 143/110
I never heard about his, Maybe others have. I guess this would be even
more of a reason to use the encrypted versions of the protocols.
