sendmail.mc file?

######################
If you have 2 or 3 MX records, will grey listing cause the sending smtp to
try the next server?
######################
When a ISP has a group of SMTP servers, how do they centralise the mail for
POP3 etc, do they sync the mail to a master server for all clients to
connect to?
Has any one got a good URL for this solition?

Does anyone know if there's any plans for a meet in Exeter?
