I am running a mail server that has a few local recipients and a bunch of forwarded recipients for one domain. All is working properly. However, there are some log messages that I find confusing. The server receives many messages delivery attempts where the user is not included in the virtual_alias_maps. All but one of them receive log messages like
Recipient address rejected: unverified address That makes sense. However, one of them receives Recipient address rejected: User unknown in virtual alias table I don't see what is different for this particular user. They all have the same domain which is the only one in virtual_alias_domains. It appears that that message made it through the smtpd check as if the user was in the virtual_alias_maps. That user id does not appear anywhere in the postfix configuration. Am I interpreting these messages correctly? One possible issue with this user was that that id was originally not in virtual_alias_maps and was added. There were no such log messages before that. They were listed in the unverified address listing. After adding the user, there were no log messages and mail was delivered. Later the address was removed from virtual_alias_maps and then the unknown messages started. Postfix was re-started after that change was made (not a reload). -- Doug
