The problem described below happens with the following Firewalls;
Zonealarm Sygate Pro Kerio 2.1.5 Kerio 4.2 Outpost
When I send a post or email from Outlook 2002 or Outlook Express the above Firewalls block the outgoing post/email. Disabling the firewall and I can send ok. I have NOD v2.5 installed. My system is XP Pro SP2 fully patched.
The really strange thing is that it only blocks the FIRST email/post I send. If I disable the firewall, send my 1st post/mail and then re-enable the firewall, all subsequent items can be sent with the firewall enabled.
Anyone any ideas?
