Re: [courier-users] Quick question about couriermlm & spam

[Bill L. <bil...@lo...>]

Hmm..strange.

If I just copy the mail user "research"'s .courier-default file to 
.courier-subscribe
(contents of .courier-default = | /usr/lib/courier/bin/couriermlm ctlmsg 
/vol2/courier/lists/CCN-Research )
and try to send to res...@my... I get the following 
error from my maillog
Jan 30 13:33:04 ns courierlocal: 
id=000C9B50.41FD528F.000005B9,from=<se...@ot...>,addr=<res...@my...>: 
Invalid address.

But just having the regular .courier-default works okay for the same 
message.

The only thing I'm doing that's not ordinary is that for this mail user, 
it's only used for the list, so i haven't implemented(well I have, but 
it's not using it) the .courier-<listname>-default to invoke the 
couriermlm. I'm doing it straight from my .courier-default, so that 
sending messages to research-subscribe@, research-help@ and research@ 
all invoke the couriermlm stuff. This has been working just fine, so I 
don't think this is the problem.

Did I miss something?

(sorry for the personal post to you Sam, I geeked the reply)
