Postfix 3.3.0, on OpenSuse 15.0
Hi to all, my first post, as a list newbie :-) I'm using postfix, along with dovecot, for about two years now, on my VPS. virtual_mailbox_domains for virtual domains of recipients, virtual_mailbox_maps for recipient's addresses. Both stored in MariaDB/MySql. Works fine. Starting a while ago, I've added getmail, for syncing my email accounts at commercial ISPs (like the sender address of this email, michae...@rocketmail.com, a yahoo account) to my own VPS. The getmail part itself also works fine and stable. But I recognized an ugly self-made side effect today, for the first time: Let's say my VPS' domain is EXAMPLE.COM, as written above used as a postfix virtual domain. So one of my private email addresses would be mich...@example.com. To get my postfix server to accept both "direct" emails (for mich...@example.com) and "getmail-ed" emails (for michae...@rocketmail.com), I've currently added "rocketmail.com" as (postfix) "virtual domain". As said, works fine for receiving "getmail-ed" mails. BUT, today I wanted via Thunderbird to send an email from sender mich...@example.com to someone_e...@rocketmail.com. And Thunderbird immediately shows me the postfix error msg "5.1.1 / Recipient address rejected. User unknown in virtual mailbox table". So it seems that currently my postfix server, listening secured (on port 587) for relaying my emails, "remembers" that he's also listening unsecured (on port 25) to receive emails for "virtual domain" rocketmail.com. Any hints how to tell postfix that he shouldn't try to catch all emails for a virtual domain, but only the ones for existing (getmail) virtual users, defined in virtual_mailbox_maps? (Of course) I've searched the net and esp. this mailing list's archives before subscribing and posting, found this old answer https://marc.info/?l=postfix-users&m=118760792501033. Which might lead into the right direction, also for my issue, but I'm not sure. Regards, Michael
