We were running 2.2 ever since it was released, and it would require
attention about once a week (mostly router core dumps).

We upgraded to 2.2e6 in February, and haven't had a SINGLE problem since.

As I see it, the advantage of the 2.2eX versions is that they have
only had portability changes and bug fixes ... no new major features.

No matter how closely you study someone's code, it rather difficult
to know it better than the original author ... and rather easy to
deviate from the original design in subtle (and sometimes buggy) ways.

By the way, I just noticed there is a zmailer2.2.e7.tar.Z at
ftp.csri.toronto.edu:/pub/zmailer ... who snuck that in there? :-)
