Hi,
Got a strange attachment problem with one of my customers - 120 branch offices and a HQ.
Offices are connected through WAN.
Mail is routed through their HQ. Exchange 2003 servers with Net IQ Mail Marshall service scanning all email for viruses and spam on port:26 then passing mail to port:25.
Branch office clients have Outlook Express which use POP3 to get mail through our ISP.
When various senders from head office send an email to all branches with attachment. 99% of branches recieve email and attachment fine but the odd two or three get the email but no attachment.
Email size reads as though attachment is there!
This has been happening for the last three weeks. No config changes have been made to the Exchange orginization or Mail Marshall?
We have checked for Viruses, versions of Viruses software which are all the same at branches, firewalls, Outlook settings, ISP, Exchange, Mail Marshall to no avail!!
If have forwarded problem mail from affected branches to myself and there is no attachment present. Suggesting attachment is being stripped before reaching client.
HQ can resend same email later on and the problem branches will get attahcment fine. It's very random and effects different branches on and off.
Any help would be apprecitaed.
Many Thanks.
