[ILUG] mailman on linux

[Vincent Cunniffe]

Hi,

I'm having a problem with a mailman installation : everything works fine up to the 
point where either a post or a final confirmation is to be sent. Adding a new user
from the webpage works and send the user an email, buy when the user replies in 
confirmation, the following error occurs (data anonymised):

	The original message was received at Wed, 17 May 2000 15:41:34 +0100
	from [xxx.xxx.xxx.xxx]
	
	   ----- The following addresses had permanent fatal errors -----
	"|/home/mailman/mail/wrapper post newlist"
	    (expanded from: <listname at hostname.tld>)
	
	   ----- Transcript of session follows -----
	sh: wrapper not available for sendmail programs
	554 "|/home/mailman/mail/wrapper post newlist"... Service unavailable

Has anyone seen this sort of problem before, and if so, what's the solution?

Regards,

Vin
