Hello, I'm pretty new to Postfix, and I'm experimenting with using it for our new inbound MTA. Is it possible to customize the following error message?
MAIL FROM: <u...@remotedomain.com> 250 2.1.0 Ok RCPT TO: <invalidacco...@virtualdomain.com> 550 5.1.1 <invalidacco...@virtualdomain.com>: Recipient address rejected: virtualdomain.com In this sanitized example, "virtualdomain.com" is just that, as is "invalidaccount". I see "unknown_virtual_mailbox_reject_code" will let me change the response code, but not the text. I'd expected to find something like a "unknown_virtual_mailbox_reject_reason" parameter, but I don't see one. Is this possible? Thanks!
