[mapserver-users] lists performance

[Ranga Raju Vatsavai]

Hello All
 
Thanks to all users who responded to 'bonced mail problem' which degrades
the performance. We are using Majordomo software and it do have a program
to manage bounced mails (semi automatically). One of the parameters it 
requires is the mailing address of the user. Well that is the problem!
to get address from bounced mail (about 500 messages/per day). My guess
is roughly we have 35-50 defunct users out 600 subscribed users. Some
of user problems are temporary and some are fatal. So if I can identify
these users (need some easy way of doing it - any help from you guys
is apriciated) then I can use bounce utility  to manage these users
separately (which will grately improve delivery times). I am providing
some sample bounced messages to help you give useful suggestions:

Note I am removing users-id and instead using xxxx and yyyy's (to maintain privacy).

and several other types of errors ...

So I need help in identifying these users without opening my mailbox and reading
these mails to get email addresses. Please let me know if you guys are aware of
any tools/scripts that can do this job.

Thanks
Raju
