we use an OES 2.0 with GW8, sometimes it happens that the GWIA can't reach the smtp server of our provider. Pinging works, but a testing telnet session on port 25 can't be etablished. On other our other maschines the telnet sessions work. After reboot everything works fine again. This happend 2 times this week.
Does someone got ideas how to solve this problem?

Best Regards
