I create a postmaster and abuse alias for root in /etc/aliases. Ran newaliases then reloaded postfix to make it take effect, but it does not. When someone tries to send mail to postmaster they get: 45.xx.xx.xx | unexpected response to [RCPT TO: ] | 550 5.1.1 : Recipient address rejected: User unknown in virtual mailbox table my statments in mail.cf look like this. alias_maps = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases alias_database = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases Does anyone know what I'm doing wrong?
The file /etc/aliases contains aliases for the server ghostname, so when you add an alias there then this alias is valid for e.g. [email protected] but no other addresses. If you want to have a postmaster address for a domain that you host email services for, then add it in ispconfig.
Many RFC require you to accept [email protected] and [email protected] at your IP address. Mailserver rejected mail to postmaster. Mailservers are required by RFC822 6.3, RFC1123 5.2.7, and RFC2821 4.5.1 to have a valid postmaster address that is accepting mail. The Mailserver provided is: 45.35.xx.xx | unexpected response to [RCPT TO: ] | 550 5.1.1 : Recipient address rejected: User unknown in virtual mailbox table Mailserver rejected mail to abuse. Mailservers are required by RFC2142 Section 2 to have a valid abuse address that is accepting mail. 45.35.xx.xx | unexpected response to [RCPT TO: ] | 550 5.1.1 : Recipient address rejected: User unknown in virtual mailbox table
Do not use @ip as this is not a valid address. You misread the RFC. Use the postmaster@address to the domain that the mail server identifies itself. Or just create a postmaster@ for each domain.
