sendmail ignores my mailertable

[richf510]

I'm installing GNU Mailman and trying to configure Sendmail with mailertable support for use with mm-handler.

My .mc file contains the line: FEATURE(`mailertable', `hash -o /etc/mail/mailertable'),

and the new mailer config:

Mmailman, P=/etc/mail/mm-handler, F=rDFMhlqSu,
U=mailman:smmsp, S=EnvFromL,
R=EnvToL/HdrToL, A=mm-handler $h $u


I've used the .mc to recompile sendmail.cf. Sounds pretty straight forward, at least to me, but when but when I try to use the mailertable functionality it looks like sendmail is ignoring my config.

My host is called usmlrs201.arrow.com.
The mailertable file contains one line:

usmlrs201.arrow.com mailman:usmlrs201.arrow.com

And I've rebuilt the map using:
makemap hash /etc/mail/mailertable < /etc/mail/mailertable

But when I test I get the following:

[root@usmlrs201 mail]# sendmail -bv justanotherlist@usmlrs201.arrow.com
justanotherlist@usmlrs201.arrow.com... User unknown

If I put entries for justanotherlist into aliases, mail gets delivered, but bypasses mailertables.

I'm not sure what other information would be useful. I could post my entire sendmail.cf if necessary...

It looks to me like sendmail is ignoring the mailertable configuration. Why?

Any help is appreciated

TIA
