We have a vendor that is setting up a web page on an IIS server which will
email folks when they purchase an item off of it. I'm not sure what they use
for a submission agent - I believe it's something they developed in-house. The
technician I'm working with isn't a programmer and doesn't really understand
the ins and outs of email and doesn't know if they can change their code or
not. The issue I'm running into is we have reject_non_fqdn_helo_hostname
enabled on the mx host they connect to, which returns:
"504 5.5.2 <eagle-store>: Helo command rejected: need fully-qualified
hostname;...helo=<eagle-store>"
I don't want to turn off reject_non_fqdn_helo_hostname but they're not sure if
they can change the EHLO name. I'm not sure where it's picking that up from,
probably the hostname. Obviously it isn't hard coded into their source code.
We can't change the hostname, as the external domain it sends from is different
than the internal domain.
If they can't figure out how to set it to a FQDN, is there an easy way to
override reject_non_fqdn_helo_hostname for just that one host? I added the
smtpd_helo_restrictions stanza this morning but to no avail. The IP address of
the sending host is in "mynetworks". It's also in the cbj_client_access file
with an "OK".
smtpd_relay_restrictions = permit_mynetworks, reject_unauth_destination
smtpd_data_restrictions = reject_unauth_pipelining
smtpd_helo_restrictions = permit_mynetworks
reject_non_fqdn_helo_hostname
reject_invalid_helo_hostname
smtpd_recipient_restrictions = permit_inet_interfaces
permit_sasl_authenticated
reject_unknown_sender_domain
reject_non_fqdn_sender
reject_non_fqdn_recipient
reject_unauth_pipelining
reject_invalid_hostname
reject_non_fqdn_hostname
reject_unknown_recipient_domain
