Does IMAP create much additional system load vs. POP3?
I would say it adds considerable load to the server. The beauty is that multiple computers can synchronize all mail folders INCLUDING the Outbox/Sent folder to the common archive, which becomes the mail server itself.
Is see little advantage if a single computer is involved other than using the mail server as a backup.
Even with a single computer however, if one uses (also) a webmail client such as roundcube etc, then IMAP once again permits synchronizing between the webmail and the single computer.
In an environment such as mine, 2 laptops, a desktop, and at times, webmail, it is a necessity. These days (also) mobile mail such as on an iPhone is handier with IMAP.
Weigh all this against more drive space required, and more resources such as extra processes running on the server.
