Problem sending emails Johnie 12-15-2004

I have a problem with sending emails which I believe is caused by my Kerio 4
firewall.

I am using Kerio 4.1.2, together with Norton Antivirus 2002 with latest
updates. For my email client I use Mozilla Thunderbird, but the problem also
occurs with MS Outlook.

When I send an email it seems to go out, and Norton AV scans it - but then
Norton cannot get it past the firewall and comes up with an error message.

I then have to retrieve the email from the "sent" folder and repost it. It
_always_ succeeds the 2nd time.

When I disable Kerio I don't have this problem, which makes me suspect the
firewall. I don't have the problem with short one line emails.

I do not suspect the firewall SMTP settings because these work okay the 2nd
time round.

I also seem to have a similar problem with posting a newsgroup item like this,
and in posting to web forums - these frequently need more than one go to
succeed - but not every time like with email.

I have posted this problem to the Kerio site forum with no replies.

TIA Johnie.

Does Kerio have the ability to utilize 'grey listing' so that in case
the machine is compromised all initial outbound requests are blocked
for the first time, but accepted to the same recipient after a retry?
I don't know, I'm reaching on this one.
