As supporting evidence, i offer qmail. Amazingly enough there are still systems running it and even some people still installing it on new systems. It hasn't been updated since 2004 and even that was fairly minimal - it had been effectively dead for a few years before that. And, unlike mysql, qmail was never even a market leader...it hadn't had time to even begin to displace sendmail before postfix came along and ate its lunch (and sendmail's too).
Qmail offered some significant benefits over Sendmail. The last new installation of Qmail that I witnessed was about 10 years ago, that was due to it being a lot better than Sendmail et al and having a LDAP configuration that was more similar to the Netscape one than Postfix - migrating to Qmail from Netscape was easier than migrating to Postfix. Qmail has some significant down-sides which include the fact that it sends bounce messages in situations where Postfix will send a SMTP 55x. This means that a Qmail server is much more likely to get into a bounce loop than a Postfix server. Qmail also isn't easier to configure than Postfix. For comparing MySQL to PostgreSQL there is the issue of data integrity features which are lacking on MySQL. But MySQL is easier to configure and run in my experience. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
