My server is a limited space mailserver set up to filter spam. Most of it's
mail is passed on ot an exchange server so it is not stored locally. I have a
handful of pop accounts that are stored locally. For years I've used mbox type
mailboxes that I'm familiar with and can access on the server when needed using
the old mailx program. They use a variety of clinets, typically Outlook and
smartphones.
I'm considering changing to IMAP because I need a single IMAP mailbox for an
unrelated reason. But I am concerned about user storage issues at least..
Currently my POP users have a max mbox size but that is how much it will store before
they "come get it". I ensure they have at least one device set to delete from
the server periodically (i.e. 1 week). So users with multiple devices get their mail
duplciated on their devices and at least one devices keeps the server emptied so their
mbox does not hit any limits.
As I understand it, when using IMAP, the user's messages are perpetually stored on the
server. So if the user is not moving their messages from their inbox to some other place
(e.g. a different Outlook pst file), that all the messages will remain on the server.
All messages are "synced" in the user's inbox or other user created folders.
Is that right? This would pretty quickly cripple those normal non-computer types that
have years of emails in their inboxes. And I don't have the storage space to allow
storing years of their mail. I also understand if they exceed their storage limit, mail
starts bouncing which is what's I'd expect.
At first I started googling how to expire the old mail, but then realized that
won't work because if I delete on the server, I understand that will delete on
their devices, too.
How do other's deal with this? Am I misunderstanding something? As popular as
it seems to be, these seem like big hurdles to overcome. Appreciate some help
for a IMAP noob.
Thanks,
Scott
Use that single mailbox with IMAP, others stay to POP(if server with
such small disks pretends to be a mailserver). It's just connection
protocol at all.
