I have the Internal Mass Mailer set up, and sometimes it sends all the messages fine, especially when the database was smaller. Now on a fairly regular basis I get the:
"Internal Server Error -
The server encountered an internal error or misconfiguration and was unable to complete your request"
message usually after it sends out anywhere between 70 and 200 messages.

Just incase it makes a difference, I do have another subscriber maillist program on my server that I send out about 3000 emails on a reqular basis with out any problems.

Has anyone else experienced this problem with the Mass Mailer?
Anyone know what might be causing it?
Any solutions?

Thanks!
