At best, a bit overdramatic a characterisation. My very informal tests suggest that all four MTAs tend to have throughput high enough that differences really don't matter. > This site actually has benchmarks of sendmail, postfix and qmail.

I note this is a 1999 test. I've heard claims (which I alluded to earlier) of improvements to Sendmail's queue-handling and delivery algorithms in much-more-recent versions. > This site has more relevant data, with a 'mails/second' delivery rate: > > http://www-dt.e-technik.uni-dortmund.de/~ma/postfix/bench2.html Sendmail 8.11.x is getting _closer_ to the present, but the current series is 8.12. (His figures may still be applicable; I don't know, really.) > For now the drop priv band aid of sendmail works, but i just wonder > how long it will. Well, consider: In effect, it does some separation of the code into security-sensitive and non-security-sensitive portions, in the sense that only a much smaller-than-previously percentage of the code ever executes with root authority: By the time any but a small percentage of it gets called, root privilege has been dropped for that code instance. In general, some of the most-effective ways of achieving better assurance of security are (1) run less code in a trusted role and (2) run less-complex code in a trusted role. Dropping privilege is a roundabout but still effective way of doing exactly that. > What i do is to simply make it known that there are better solutions > to MTA applications than sendmail.
