Undeliverable and SMTP issues

[RichardPotts]

Hi all

Running SBS2000 with DNS and Pop3 from ISP mail provider.
Majority of the time everything runs fine - but at least twice a day (intermittent) the SMTP virtual server appears to stop and all messages are queued in the undeliverable queue - SMTP log and visibile status shows no problems and reports it is working - once stopped/started the queue clears ? Any ideas ? Are there any size restrictions / timeout settings that are activated other than those in the SMTP properties section i should focus on . Would additional events like the DHCP or DNS settings cause the issues ?

Any ideas greatly recieved.

Although, I don't have a solution to this problem, I can say that I believe I also have this problem with our Exchange Server.

Any help to us would be much appreciated.

Thanks,
Gary
