[Mailman-Users] Non-member filters & regular expression match

[Godfrey]

Hello

Not being too knowledgeable on regular expressions could some one please 
point me in the right direction.

Under non member filters

I would like *@compudoc.co.za and *@compudoc.za.org and *@hamshire.za.net 
to be in List of non-member addresses whose postings should be 
automatically accepted

The list I have is

^.+ at compudoc\.za\.org$

 From the various posts to the I have managed to glean via google above 
statements should work but it does not could some one please assist me with 
this.

Thank you
