Off-topic: iOS 9.x issue with POP3 accounts and attachments
« on: October 10, 2015, 12:26:05 am »
It seems that Apple has messed up something with their recent iOS update:

Maybe this is Apple trying to get everybody off of POP3 and onto IMAP.

Speaking of POP3, I just had a revelation after reading this passage below (from [1]) (and then the corresponding RFC [2]):
Quote
If you are using the Post Office Protocol to keep mail on the server indefinitely, then you are in fact abusing the protocol. POP has never required that maildrops hold mail indefinitely. Indeed, RFC 1939 § 8 is clear about the fact that servers are quite free to outright delete messages that you've retrieved but not deleted yourself ...

(I had never thought about that fact.)

In 1996, it probably wasn't common to access a mail account from multiple devices.

People would have a "computer at the office" (Northgate or Gateway 2000, remember those?) running maybe ccMail hooked up primarily to their office mail system.

And all that...

Things have progressed since then.

Still - I agree that POP3 starts being a burden once you get to too many messages, at least used naively (as most desktop mail apps do).

That's why Google came up with "recent" model for Gmail's POP3, and their server, in fact, defaults to "report each message over POP3 once and only once" (which would be seen as "old messages disappearing from server").
