[cobalt-users] [Qube2] ipfwadm deny port 113

[Mike Vanecek <nospam99@xxxxxxxxxxxx>]

If one uses a deny all policy via ipfwadm, should port tcp 113 (ident) be
allowed? It would appear that some mailers send back an ident before accepting
mail. If tcp 113 is blocked in the firewall, will this cause delay or problems
with email delivery?

Thanks, Mike.
