Quoting Steve Simon <st...@quintile.net>:
I am fairly sure the problem is to do with RAM size rather than the
raspberry pi per-se.
4000 messages takes up a lot of space - and upas stores messages in RAM.
Personally I save needed mail messages in named archives and try to
keep the number
of messages in my inbox doen to the 10s.
Erik has nupas which reworks much to keep a file per message on disk, though
I'am not sure how thsi works with gmail (imap4 I assume).
-Steve
nupas has done very well with large mailboxes, although I haven't
accessed a multithousand-message account with less than 256MB ram.
I'm unfamiliar with rpi-class subparcomputing but nupas should work
okay with comparatively little ram. the primary reason that we
haven't pushed to replace upas with nupas by default in 9front is
insufficent testing with the mbox format.
