Do it yourself mail systems

Through my position here at Word to the Wise I’ve interacted with dozens of companies over the years. Some companies outsource the mechanics of email sending to email service providers, others buy a software or MTA solution from one of the many vendors out there. For both these groups delivery problems are usually issues with permission or user expectations. Technically there are few problems with sending, bounce handling, unsubscriptions and rate limiting. The commercial software, either as created by an ESP or a vendor, typically does these things well.
The last group, those who use a home built system, are a whole different story. They often do no bounce processing relying on the underlying mail transport agent (typically qmail) to do all that work. The problem is that a general mail transport agent handles bounces for a particular email send, but does not have any functionality to handle future emails to addresses that bounce. Consequently the list does not get bounce handled, dead addresses pile up and their delivery rates plummet.
