UK sendmail configuration 2.1

[Laurie Cuthbert]

We have been using this for some time without any problems but now we
want to do something a little different and I wondered whether any of you
may be able to offer some simple advice.

We have started trying to use "POPmail" on PCs for secretaries who do
not need to know how to log on to a unix host. The problem is that the
UMN PC POPmail does not allow a local hosts table - you either need a
nameserver or you use the IP address.

At present we are not using a nameserver, although we will be eventually.

When using the IP address for the server, POPmail generates a From field
of the form user@[138.37.32.200] - sendmail complains about that.

We have tried the things that seem obvious to us, like putting
addresses of the form [138.37.32.200] or just 138.37.32.200 in the
local.chn file to try to convince sendmail that the address is itself -
but it still complains.

Any suggestions would be appreciated.

Regards
Laurie Cuthbert

That is a perfectly valid address. 'sendmail' should not complain. Check
your 'sendmail.cf' to see how it is handling it. You need to be sure that
if [...] is your own host address the 'local' mailer is selected, and if not,
the TCP (or equiv) mailer is selected.

The usual trick is to run the [138.37.32.200] through a name server or
host lookup, as with $[ .. $]. If this results in your hostname, the
address is local.

Something like this should do the trick (in ruleset 0):

R$+<@[$-.$+]> $:$[[$2.$3]$]<>$1<@[$2.$3]
R$w<>$+<@[$+]> $#local $:$1
R$+<>$+ $2

Of course you can just do:

R$+<@[138.37.32.200]> $#local$:$1

That should have worked! Perhaps you forgot to restart the sendmail
daemon after doing this (a *very* common mistake).
