Hi,
Is there any way in Postfix for it to handle Google's delivery problem?
I have been struggling for some years with Sendmail, and the problem that Google does not support multiple destination domains. When the MTA looks up the MX record for:
f...@gmail.com
b...@conglomco.com
b...@university.edu
And finds they MX to Google, it logically puts them in a single transaction.
And then Google for NO LOGICAL REASON tempfails all the recipients except the first domain. With a long recipient list of which many resolve to Google, this can result in a lot of re-queue and wasteful delay.
If Postfix has some workaround for this I will happy switch off Sendmail.
Help!
