I look after a site that is running Exchange 2003. There are about 150 users and since last week, I have noticed that there are an unusually large number of messages that sit in the 'Messages Pending submission' They all seem to eventually get out but going through the messages, probably 75% of them are spam which our GFI MailEssentials does pull out. Currently, as I monitor the exchange server, there are 186 messages and last week, I saw it as high as 500. I don't think that this is normal but what can I do about it?
