Keep connecting to remote host on port 7869

[Frank Cheong <fch () hktb com>]

I got a question with my redhat linux host (which is a mail host) keep 
connecting to other remote host quite frequently on remote port 7869 and I 
m receiving these firewall log almost every minutes. Could someone give me 
hints so that I can further isolate the problem or trim down the scope to 
find out the real cause.

Below is the firewall log (IP address being modified) :

10/23/2002 11:13:36.640 -     TCP connection dropped -     
Source:123.123.123.123, 51321, LAN -     
Destination:234.234.234.234, 7869, WAN -     Type: 786 -
     Rule 66
