[Mailman-Users] Mailer error

[Armen S. Minassian]

Hi guys, First I offer you my apollogies 
I am from Armenia and Thanks for your help.

I'm new in this mailing list and first time install mailman.
I'm creating new list (test), updating /etc/aliases file (run
newaliases).

When I sent mail to test-request at domain.com I get mail with message:

554 5.3.0 "|/usr/local/mailman/mail/wrapper mailcmd test"... unknown
mailer error 2

I'm using smrsh feature in sendmail.cf and creating simlink:

/usr/adm/sm.bin/wrapper -> /usr/local/mailman/mail/wrapper

What I forgot or don't know?

Thanx for advance
