I have been using Imap and Pop3 together for over a year. I read my mail from
as many as four computers. Some computers only support POP3, but I like IMAP
better; therefore I use IMAP when I can and POP3 when I don't have a choice.
In all my setups, I set turn on the option "Level messages on the Server" for my
POP accounts. Each of my POP3 mail clients kept track of their last-read-PID
number (the message id of the last message it downloaded).
Therefore when I get on the machine I use daily. I only download a few message
everytime a I check my message. But When I read my mail from my a computer at
home (since I only use it on the weekends) it will have to download 50-100
message before I get to the messages I haven't read before. Even though I have
read the message on a different machine, my email client will download it since
it uses it's own last-read-pid number.
Using IMAP blends in very nicely. I see all my messages that on the server with
out download them (the machine only loads the headers until I ask to read the
body of a message). When I get a SPAM or junkmail message I delete it (and
expunge it -- at the end of my session). Then this message is never download to
any of my POP machines when I load them, but my pop3 machines will still
download all the other messages that are left on the server that it (that pop3
client) haven't downloaded yet.
Running this way tends to consume alot of disk space on my ISP. Therefore I
keep an extra POP3 "profile" on my master computer that I use just for
archiving. I load that is configured to "remove messages from server after
downloaded". When I have alot of mail still on my ISP mailbox (200-400
messages) I load what new messages I have in my main mail client, then quick
switch over to my extra pop3 archiving "profile" and download my mail again.
Since that "profile's" last-read-pid hasn't been updated since my last purge it
will download all the messages I have in my mailbox and delete them from my ISP
mail folder. This process takes a while, but when done, I double check that
very last few messages to see if any thing was received since when I loaded
messages onto my main mail client. (If so I just forward it back to my email
account on my ISP, so I can answer it with my "main email client".
I don't think you have to worry about using IMAP and POP3 together, If you
understand delete/expunge on IMAP and that each POP3 client has its own
"last-read-pid" number and that POP3 accounts of the option of "leaving messages
on the server".
Have a good Weekend.
