postfix and relayhost question

[Patrick Hsieh <pahud@pahud.net>]

Hello list,

I configure my relayhost in main.cf of postfix.
When I send a mail with multiple recipients in an envelope, how to make
it just one single smtp connection from the postfix server to the
relayhost? I tried to use netstat -nt to view the smtp connection and
found postfix use 5 smtp connections to my relayhost. It seems to divide
the envelope into multiple single recipient and send them individually.

Idea?
