Grouping doesn't give much performance in this case since less than 5% (IMO) of the recipcients have the same MX. > When one mail is sent to the list, one copy goes for all *.fr recipients, > one copy goes for all *.de recipients and so forth. That's bandwidth and > delay reduction for you and where Qmail sucks big time IMO. You are still in the old UUCP times with your 'one copy to all *.fr recipients'. I don't think that all *.fr subscribers have the same MX. You can only do better with sendmail if you send, lets say, 100 messages to the same MX. > Qmail is faster but sends N times as much data as sendmail. Bad bad bad. Nope.
