Zbigniew, you're simply taxing your Internet connection. Your connection is
1 Mbit. The message is 6 Mbytes, which equals 48 Mbits (roughly). Add in
competing Internet traffic, and what you've got is a bottleneck. You might
have some options in ISA for limiting bandwidth to certain protocols (like
http for example), or giving preference to SMTP (I'm not an ISA expert, so
please don't ask how), but other than that, you'll need to pump up your
bandwidth to improve things significantly.

Subject: [exchangelist] Problems with SMTP connector


I'm a administrator of SBS server 2000. I have performance troubles with
SMTP mail conector, becouse if any mail greater than 6MB show in queue to
release very strong dicrease performance of proxy server to the internet.
Server has 2 network card (internal and external) and working ISA and is
connectet to the 1Mbit speed frame relay line. When this big mail is
released the normal situation came back.What I should do.
