How to reproduce
SPOOF_PROTECTION=1postfix-regexp.cf:/^test[0-9]@domain.tld/ [email protected][email protected]=> Mail gets rejected with error message:
postfix/smtps/smtpd[1312]: NOQUEUE: reject: RCPT from xxxxx[xxx.xxx.xxx.xxx]: 553 5.7.1 <[email protected]>: Sender address rejected: not owned by user [email protected]; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<xxxxxx>After adding
/etc/postfix/regexptosmtpd_sender_login_mapsit worked as expected.For LDAP this probably has to be fixed in a similar way.
Before I discovered this bug I set a alias for a whole domain in
postfix-virtual.cf:@domain.tld [email protected]. This worked for receiving mails as expected but not for sending mails. The sending was rejected with same error as above. Although the file/etc/postfix/virtualis included in thesmtpd_sender_login_mapsso this might be a bug in Postfix?Sidenote
When I was trying to build this project, I first got a error message from docker that it couldn't find a file. Until I realized that there is git submodule I hadn't cloned yet. I suggest adding it to the Readme (maybe create a build section with additional infos?) in case someone stumbles upon the same problem.
