I have a domain xyz.com. When I attempt to send users of this domain
e-mail amy@xyz.com, joe@xyz.com, mark@xyz.com, each user will receive
the message multiple times. As an example, if I sent amy@xyz, joe@xyz
and mark@xyz, each user would receive the message 3 times (one for
each user name).

(see sendmail.mc below) Ubuntu Linux server 6.10. I have attempted
multiple things to prevent this, but have only made a mess of the
sendmail file. I am hoping that someone here can resolve this
issue.

Thanks.

Sendmail won't do that...

This is a very strange definition - what are you trying to achieve with
that? Seems like maybe you're trying to do some sort of "virtual
domains" with procmail and botching it.

Oh. Maybe I should have been searching procmail then. I could not
find any issue under sendmail.

Quite possible at this point. What would you suggest as a default? I
do have two domains being serviced, but amy@xyz.com is the same as
amy@abc.com.

Thanks Per!

The suggested default is of course what you get if you don't put in a
define for LOCAL_MAILER_ARGS at all - you already had
FEATURE(local_procmail) which will use procmail as LDA. However the
above definition suggests that you (are supposed to) have some
mailertable entries and custom procmailrcs to do "something", this will
break then - hence the question above. If you don't know what you're
doing, it's difficult to give advice...:-)

Hm, actually I see now that you have FEATURE(local_procmail) *after* the
LOCAL_MAILER_* defines, it will override them, so thye're irrelevant.
Maybe you should just take out everything that you don't know why you
have there? In any case, procmailrc rules that try to resend the message
based on the header contents can certainly cause the problem you're
seeing.

The standard way to handle that (assuming 'amy' and everyone else are
local OS accounts) is just to put both domains in class {w}, normally
via the local-host-names file. Cw entries in your .mc (you have one for
xyz.com) will do the same, but they should really be in a LOCAL_CONFIG
section.
