We are trying to do an interesting setup w/ PG.
Everything I've seen says we cant do 1 part (we're pulling email addresses from a LDAP server, and would like to reject all email not to one of those addresses. Everything I've seen only allows the domain to be redirected to the real mail server, and let it reject if the address doesnt exist). The issue we have right now is we're getting the following error:
_Connected_to_192.168.0.100_but_my_name_was_rejected./Remote_host_said:_501_HELO_requires_domain_address/
@4000000046c1b9c63056afec status: local 0/10 remote 0/20
I've googled for that, as well as just parts of that error, and only found 1 thing, in german. The translation didnt make much sense though.
It's not in production yet, so testing is being done via telnet to port 25, with the standard helo blahblah.blah mail from: rcpt to: data etc etc etc.
