[Mailman-Users] Messages not going through

Hi there, I'm using mailman 2.1.5pl on my hasweb hosted server. One list has only a dozen or so members. On that list messages go through all the time. The other list has over 500 and no messages seem to be going through. They make it to the archive. Thank you for your help. -Zach

[Mailman-Users] Mailman limitations?
