Email account standard ports [answered]

When setting up email accounts, it would be nice if standard ports are predefined. E.g., IMAP4 SSL standard port is 993, SMTP SSL standard port is 465. Needless to say, the user can change that if it's different to the standard one ;-)

Standard isn't necessarily standard. You broadly have 4 ports to play with in totality, depending on the configuration and whilst for IMAP there's a certain logic (143 by default, but 993 if SSL is selected) it's far from clear with SMTP. SMTP without encryption is 25. SMTP with TLS is 25. SSL is 465, the mail server may accept one or more of these.

steph, this may not be an RFC type of standard, but these are well known ports. SSL is the tricky one as it can be 465 or another one (can't remember), but you could settle with the most popular one. Of course anybody could set up sendmail listening to any port, but then you know what you're doing.

The point I'm trying to make is that for SMTP you can't just 'guess' the configuration of the mail server. Both 25 and 465 are valid and one is no more common than the other, arbitrarily adding one will confuse the others. IMO @otto and that ticket is the correct course.

@steph Predefined value of port number would change after toggle encryption. So no confusing, I think.

Agree that it should be filled with atleast most "normal" port numbers.

Also in the case of (no)encryption types it could change "default" depending on what you select in those combos.

This is how for example kmail doing it. Ofcourse it sometime still not work but it will "just work" for many endusers instead of like now where you must know everything. Not even me as a geek always remember every port etc...

Let's mark this one answered in favour of: https://together.jolla.com/question/1491/configure-email-accounts-automatically-like-thunderbird/

Of course allowing for fully manual configuration shouldn't go away.
