I have a working exim setup with virtual users, working alright, except for when I try to send email to certain servers. These servers reject my emails because of #5.1.3 Invalid character ('@') in username.
The offending header parts seem to be:
Return-path: <"
[email protected]"@smtp.example.com>
and
...(envelope-from <"
[email protected]"@smtp.example.com>)...
The problem is that I cannot find where and why the usernames are being generated like this.
My router for submission is:
dnslookup:
driver = dnslookup
domains = ! +local_domains
transport = remote_smtp
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8
no_more
And the respective transport:
remote_smtp:
driver = smtp
What can be producing this problem?
