It is really personal choice. I think if bind can be in /usr/local why not sendmail. There is not really a working MTA until you configure it. I've used sendmail, exim/dovecot, and postfix/cyrus. We use the later in a small production environment (about 100k emails/day) and that has worked well for us. It (postfix) is hard to get a handle on as is sendmail for different reasons. For a while the sendmail folks put all their efforts in sendmail.com and did little or nothing with the open source version. For someone just starting my 2 cents would be, not sendmail. Configuring it is a unique experience. Postfix has 100s, if not 1000s, of options. Points in its favor: good, documentation, stellar mailling list [how often do guys like me get advice from the author :) ] If you come from sendmail as did, exim is very different in terms of mail queue management and reporting. I used it because I could not figure out how get sendmail to relay for a windows application with some strange configuration limitations. I also had never heard of OpenSMTPd. If I were starting from scratch I think that would be my first stop. Otherwise SMTP is fairly complex, better the devil you know IMO. Doug
