Hi,
I read this over and over. The majority of people appears to use postfix or 
qmail as smtpd, with most of the other components being from the courier 
suite. I.e courier pop3, courier pop3s, courier imap, courier maildrop, 
courier related squirelmail. Is there some reason why the courier smtpd is 
unpopular? Does it lack features? Does it not perform as well as postfix or 
qmail? Or is it simply not deployed as widely and hence not widely trusted 
/ supported by users?

Most benchmarks indicate that qmail buys file security for performance and 
is fairly slow compared to postfix. How does the courier smptd compare to 
that. I've googled and searched archives, I couldn't find anything 
measuring courier's performance...

So far I have experience with sendmail and qmail. qmail is a drag because 
of non-develpoment, too many patches for functionality and mail handling 
design errors. The Courier MTA looks like a good choice, as does Postfix. 
But then again if all of the backend programs MUA and filtering is courier 
stuff, why not use the courier smtpd as well? Just wondering...
