OT: replace POP3 with IMAP directly

[Rino Mardo]

hi. a little OT here i'm wondering what are the requirements to replace
POP3 with IMAP?  in my fetchmail i download emails using POP3.  now i've
learned that IMAP doesn't require the user to do POP-before-SMTP hence
with that i don't have to check for emails before being able to send out
emails.

is this just a straight-forward replace of the keyword?

thanks.
