[Mailman-Users] Welcome message

[Hung Phan]

Hi, everyone

My Mailman mailing list doesn't send out the welcome message ANYMORE.

The lists are config as an announcement list and to send out welcome  
message to new users. Because I want to make the welcome message for  
each of the list, I specified the content in the new-user welcome  
message, but remove the content in the subscribeack.txt file.

The users are added into the lists, but no welcome messages send out  
to them. When I unsubscribe them, I'm - as the admin - receive the  
leaving message (because the lists are config to send the  
unsubscribes to the admins)

In OS X Server Admin log, it shows that email was sent out but the  
users never receive it!?!

Can anyone shed some light on this problem, please?

Thank you,
