Any advantage to the IMAP functions?

imap mail

[cameraman]

To send mail from script, I've always used the htmlMimeMail class; I prefer smtp over mail and that class does all the dirty work. I guess it's showing its gray hair but it's served me well, it does everything I need, and as 3rd party code goes I get along with it well.

This evening I've been toying with imap. I was about to look at the composition & sending stuff but it made me wonder, is there any advantage?

IMAP functions are used to communicate with mail servers usually to manipulate mail that is already there, no necessarily send mail. If you are looking for some good mailing packages take a look at PEAR: Mail [pear.php.net] and PEAR: Mail Queue [pear.php.net].
