[MlMt] Probable New User with POP Question

[Jack Stewart]

Hi,

I have been using email for many, many years but always with the 
same client app which only handles POP - no IMAP capability. I 
have about 100,000 emails archived over the years in 6 different 
POP email accounts and 500 mail boxes, which I want to retain. 
The accounts can be changed from POP to IMAP.

I'm liking most of what I have read about Mailmate and want to 
use it but I am completely inexperienced with IMAP, have no good 
friends who use it, and am wondering:
     1) What transition problems from POP to IMAP will I encounter?
     2) What is not to like about IMAP compared to POP?

Sounds simplistic I know, but I do not want to risk regretting 
the change and the Mailmate manual says nothing about POP or 
transitioning from it. (e.g. Will I be able to easily retain my 
existing 500 mailboxes with their present contents?)

I Would very much appreciate any references, thoughts or comments.

Thanks in advance,

Jack
