There are different implementations, all of them standarized: While imaps (tcp/993), pop3s (tcp/995) and smtps (tcp/587) make use of specific computer ports, imap, pop3 and smtp using "STARTTLS" keep the same ports that their non-encrypted counterparts (143/110/25) to transmit clear text credentials protected. When/why using one or another? Well, when opening ports is not possible (consider a restricted environment) or as Wikipedia¹ explains, independency and transparency seen as a plus when using this extension. ¹http://en.wikipedia.org/wiki/STARTTLS Greetings, -- Camaleón -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
