Very Computer

I'm having massive problems configuring Sendmail.  First, some background:

I have Sendmail installed on a Linux box that is a webserver/DB server for
two sites.  Email for these two websites is handled by a completely
different (Windows NTMail) machine.

The problem I've got is that sendmail seems to think both domains are local


everything I can possibly think of - DNS, sendmail files, system files, etc.

Here is the output from: sendmail -d0.4 -bv root

Version 8.12.5

(The commented fields I have been messing about with to try and get it
working, to no avail)

In short, there is no reference to "freetrawl.com" and "policyplus.com" in
any of the Sendmail configuration files, so one presumes it is simply
picking this up from DNS because 212.113.198.51 and 212.113.198.52 are bound
to the machine (as its the webserver).

I have tried manually adding the correct SMTP server for the two domains in
mailertable as follows:

freetrawl.com     smtp:[mail.jpci.net]
policyplus.com    smtp:[mail.jpci.net]

..but this only seems to work - bizarrely - for some addresses at the


before.

Basically the only domain sendmail should consider to be local is
"lists.policyplus.com" (its also running Majordomo), and obviously the
various localhost permutations.  Everything else should be deemed foreign
and handled accordingly.

Can anyone give any assistance on this?

To get effective list of local email domains use:
echo '$=w' | sendmail -bt

To stop sendmail from modifying $=w you specified set DontProbeInterfaces
option to true and specify local email domains yourself as described in
http://www.sendmail.org/faq/section4.html#4.5

*.mc file fix:
define(`confDONT_PROBE_INTERFACES',`True')

I may disagree with the following *random epigram* :
O imitators, you slavish herd!
                -- Quintus Horatius Flaccus (Horace)

Doing a query on $w still showed all of the IPs (and resolved domains) bound
to the machine, even with DontProbeInterfaces set to true (ie.
"define(`confDONT_PROBE_INTERFACES',true)dnl").  In the end I've fixed the
problem by renaming the machine itself.

Not a great solution, but it'll do.

I've often thought that a nice feature to add to sendmail would be a
list of domains/host names for sendmail to DELETE (unconditionally) from
$=w ... if present. That would have solved so many problems in the past
(which were all fixed by just renaming the box ...)

(Perhaps a more generic FEATURE would be a list of values to DELETE
(unconditionally) from a specified class. Now that would be cool ...)
