[Mailman-Users] Some of my Mailman mailing lists don't work but some do.

[J.R. Constance]

I recently transfered hosting from one service to another. I have  
hosted accounts that use mailman mailing lists. On one account  
(domain) all of the mailing lists seem to be functional. On the other  
at least one of the lists is not working. I can log in to the admin  
section and from that side everything looks normal. I can send  
invitations or subscribe members, and it tells me "Invitation sent  
successfully" or "Subscription successful" but no invitation or  
welcome emails are received.

I have successfully created a new list on this account and it works  
fine.

Any ideas what might be the problem, and what I can do to fix, short  
of recreating the mailing list(s) that are not working?

Thanks,

J.R. Constance
