What version of Surgemail are you running? And on what platform? That
might be useful info.
For all domains hosted here, outgoing email for them is sent from
mail3.lcrcomputer.net(and I have well over 100 domains here). I am
running mirrored servers here with this set:
g_received_name "mail3.lcrcomputer.net"
The host names are mail3a.lcrcomputer.net and mail3b.lcrcomputer.net
and are behind a nat box. However the all banners are tagged
mail3.lcrcomputer.net because of the above setting. The forward on the
public IP address for this is mail3.lcrcomputer.net on ip address
209.172.152.5 and the reverse points back to mail3.lcrcomputer.net.
What you are calling the telnet header is properly called the banner.
The FQDN announced does not have to relate directly to the domain in
the From address field. However the ip address reverse lookup needs to
match the FQDN and the FQDN needs to have an A record that matches the
IP address connecting to the other
mail server and the FQDN needs to
match the name announced in the banner.
Again, the banner or FQDN does not have to relate directly to the
domain in the From field in the email. However SPF records for the
domain should list the IP address or FQDN of the sending
mail server
which should match the name announced in the banner.

Hi Stephen,
Yes, both domains have proper PTR records, reverse DNS and SPF
entries. Many universities, particularly in Europe, are checking that
the telnet header matches the FQDN and rejecting if it does not.
I seem to remember that in earlier versions of Surgemail that
there was a config setting that would allow admins to pre-set the
webmail log-in domain. Is that still a possibility? Any other ideas?
Thanks,

run many virtuals and have never experienced this issue you are
describing. Does your FQDN.org have a proper reverse entry in DNS (you
didn’t provide the real name, so I couldn’t check it myself)? And do
you have a proper SPF entry for both your domains that include the
FQDN.org?
Hello,
I have mirrored
mail servers hosting 2 domains. I am having trouble
with mail rejections from many recipients based on the telnet header
not matching the FQDN for the
mail servers. When I change the
surgemail.ini file so that the vdomain name matches the FQDN for the
server, the FQDN becomes the domain listed for Surgeweb login and users
cannot login to Surgeweb.
My surgemail.ini has the following lines:
vdomain address="1xx.xxx.xxx.xx1" name="MXdomain.org" ---This works
for Surgeweb but the Telnet banner is the MXdomain.org and the mail
servers reject our mail.
My surgemail.ini has the following lines:
vdomain address="1xx.xxx.xxx.xx1" name="FQDN.org" ---This makes the
Telnet banner match the FQDN, but users cannot log into Surgeweb
because their login becomes
rather
than.
Any advice on how to correct this problem is greatly appreciated.
Thank you.
