I download a copy of my mail on my Android phone over POP3 and possibly delete uninteresting messages, for real, on the server. I'm using K9. Then I'll eventually download the remaining messages on my laptop and remove them from the server. A number of Thunderbird filters move messages to their folders and I backup them daily off site. If I stay weeks on vacation, I check my current mail on my phone and that's it. If it's vacation I don't care about old messages. Customers have a copy of them anyway. I've been running like that for at least 12 years, no need for IMAP. Well, maybe if I could access my Thunderbird directory over IMAP, but it's not really important. Running my own IMAP server would be such a small improvement that anything else gets past it in the queue.
