I manage a few large enterprise mail systems with 10M + active accounts. A lot of them are legacy systems that we gained through acquisitions. I generally have to support them until we can get the accounts migrated onto the main platform. They are a mixture of exim, postfix, qmail, and sendmail, and quite often are in a poor state when we first get our hands on them. I have to say when you are getting mail routing issues exim is by the far the easiest to debug mainly due to the -bt option. When you combine it with the debug flag it produced a very detailed output on the mail routing. I have never found such a feature in all the other MTA's above. The configs are also very readable unlike sendmail.
