my post : -- personal opinion and what i heard, so its not a public or general opinion
people said that sendmail was build in a safe world.... and its not a stong and reliable web server. however sendmail isntallation is easy.
qmail is a tough and reliable mail server, but (most people said that) its very hard too install
hmm now a day, there is postfix, people claim thats.. as easy as installing sendmail and as tough as qmail
i my self using qmail as webserver
