[cobalt-users] Email not being delivered. RaQ3.

["FantasticMoms.com" <admin@xxxxxxxxxxxxxxxxx>]

Quite frequently I send messages that just don't get delivered.

I have a Raq3 with 512MB RAM, and reverse DNS lookup has been set up for
this domain.

I have been sending test mailings to various addresses, and it seems when I
send 10 messages using my RaQ, 2 will simply go missing. If I send 10 using
my ISP mail server, they all seem to arrive. This seems to be happening
quite often now.

I am using Outlook Express 6.00.2600.0000

I looked in my email logs after sending a batch of 10 emails.

In my logs only 9 emails were listed, and of those 9, only 8 arrived at the
other end.

Of the 9 messages in my logs, 2 said "stat=Deferred: Connection
reset by smtpsrvr.btconnect.com" and 7 said "stat=Sent (Submitted & queued
(23/msg.29864-1))"

So is this a RaQ problem, an outlook express problem, or a receiving
problem?

How can I find out?
