Why use procmail when sieve is so much more powerful?
First, I have a lot of procmail recipes over many years. Second, there are quite a few things that sieve can?t do that procmail does well (for just one example, calling external programs).
One of the things I do with Procmail is look for certain key phrases in email to a particular special account and if found, send an email that includes the line containing that key phrase to my cell phone text message address. It's easy to do with Procmail and formail (which is part of the Procmail suite); I haven't a clue how to do that (if it's even possible) in Sieve.
Clue: http://www.iana.org/assignments/sieve-extensions/sieve-extensions.xhtml
and

More clues are available.
I think those who advocate getting rid of Procmail in favor of Sieve are those whose interest is in sorting mail into folders. Those of us who advocate using Procmail are those who use Procmail for other purposes.
I have found very little that procmail can do that sieve cannot, other than being a nightmare to debug if something goes wrong.
Just my 2¢.
