That's an odd place for dialback to fail. Perhaps your hostname doesn't
resolve in DNS?
Start python from the command line, and enter:
import courier.config
print courier.config.me()
The name that's printed must be valid in DNS, or many sites will reject
mail from you (possibly DSNs).
Many thanks for the advice. I'm a tad confused at this point as I don't
really know enough about how Courier communicates with other
mailservers. There is no "me" file so above commands just gave the FQDN
for the server machine hta21.trinity.asn.au. This is not accessible
directly from outside the LAN. All external email to domain
trinity.asn.au is directed to our external IP address, and we forward
port 25 from the router (which I gather would be a typical small system
setup). I have set the defaultdomain file to trinity.asn.au and that
appears to work fine. We have been running Courier-MTA for 2 and a half
years without any apparent connection problems, certainly nothing
visibly associated with DNS resolution.
We also have the esmtphelo file set to mail.trinity.asn.au which is not
a machine inside the network - it is just a dummy identifier.
Is it that Courier is sending DSNs with the full machine hostname that
is causing this? I haven't tried setting the me file as I'm still unsure
what I'm doing. I'll readup a bit more over the weekend.
cheers, Ken
If that's the problem, you should create /etc/courier/me or fix your DNS
records. See the man page for courier(8) for information.
Gordon,
