Two Welcome messages combined

Hello everyone!

Could someone help me configure the welcome message sent out by the
majordomo.
I've created a file listname.intro. Now any newly subscribed user gets
a 'welcome message' which consists of two parts: the first part is generated
automatically by majordomo and the second part, which is the content of
listname.intro, is appended to it.

However, I'd like only the content of listname.intro file to be sent out --
not the automatically generated generic part sent by majordomo. Is there a
way to suppress the automatically generated part (by majordomo?)

Thanks in advance for any tips.
