I've been looking for a replacement mail server, I've been using a Communigate Pro server to send my mail, over time it's evolved and now not only sends my mail, but mail for several applications, it's sending about 750,000 - 1.5 Mill a week and was never setup to do this.
After following several tutorials on setting up postfix at basic level on CentOs for my VPS, continue to get the following:
-bash-4.1# postfix start
/usr/libexec/postfix/postfix-script: line 317: cmp: command not found
postfix/postfix-script: warning: /usr/lib/sendmail and /usr/sbin/sendmail differ
postfix/postfix-script: warning: Replace one by a symbolic link to the other
I've been over my head with threads which never describe my simplest of needs, so I will ask it here: To be able send mail with the mail() function in PHP, using my own server. I'm not interested in setting up an IMAP/POP server, just to be able to send this mail from PHP..
I would expect to find some howto about this elsewhere, so do anybody know about one?
Sendmail is the default SMTP (Simple mail transfer protocol) server installed on CentOS and although it can be slightly more complicated for beginners to learn than similar alternatives such as Postfix, it can be quite powerful and useful to learn. Sendmail by itself as the name suggests is a MTA (Mail transfer agent) which is useful for sending emails from your server to other servers.
