Hello, I've just received a request from a colleague that looks after our exchange server. Currently I have port 102 opened up to allow x.400 mail to be sent to a relay host. But, the new request has asked for port 25 (smtp) to be opened up. I'm a bit concerned about this and was wondering if anyone could (roughly) give some advice on the pitfalls in doing so. My Gut reaction is to tie down the destination IP address for outgoing then just permit replies from the same external host and probably proxy it too. However, my colleague has also asked if this could be allowed to all external hosts. This is the part that concerns me. So...the question is...1) permit or proxy and 2) what's the risks here Many TIA, Craig. __________________________________________ Craig Martin IT Support Officer Queen Margaret Hospital Fife Acute Hospitals NHS Trust Tel: +44 (0)1383 623623 Fax: +44 (0)1383 627066 email: craig.martin () faht scot nhs uk www: www.faht.scot.nhs.uk Legal Disclaimer : This e-mail is for the intended recipient only.
