Postfix suggests these packages on install:
procmail postfix-mysql postfix-pgsql postfix-ldap postfix-pcre sasl2-bin dovecot-common postfix-cdb postfix-doc
I know what procmail and dovecot are. It's the rest I'd like to know about.
Info about my server: it's a VPS and I am the only user. I have multiple domains. I plan to use user accounts for email addresses because that sounded simplest. So these would be my email addresses: email@example.com, firstname.lastname@example.org, etc.
I set up an MX record pointing at my server's IP address which is mail.mydomain.com. (There is no corresponding mail subdomain, that's just the address of the MX record.)
Any help would be greatly appreciated. If you have a suggestion on whether to use dovecot or procmail, that would be appreciated also.
