Thanks. I tried everything on the page 
http://wiki.list.org/display/DOC/4.78+Troubleshooting-+No+mail+going+out+to+lists+members 

but nothing helps. Permission is correct. The qrunners and the MTA are 
all up and running. Log shows that it is sending out acknowledgements, 
auto responses, and daily digests fine, but it somehow skips sending the 
message itself.

I tried to strace the outgoingrunner, it does the following when a 
message is posted.
1. opens the message file in the out folder,
2. opens config.pck,
3. opens another message file in the out folder (seems user notification)
4. opens config.pck again,
5. establish socket connection and sends a message.

Apparently, it skips sending the original message file after reading 
config.pck. I went through the configuration options but couldn't see 
any option that could have turned off message delivery. What could have 
gone wrong?

Thanks,
