I have been using mxtoolbox.com, for, among other things, to test if my e-mail server allows relays. Has anyone experienced any reason I shouldn't be using this nice site?

Only allow authenticated Outlook clients to send email from your server. This will stop most inside garbage email Trojans, unless the Trojan is smart enough to piggy back off of outlook. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dave Stafford Sent: Friday, April 25, 2008 9:45 AM To: Exchange Discussions Subject: E-mail/Spam blasts on Exch 2003 Hopefully someone can give me some help or guidance. I am having a problem with my 2003 Exchange server (on a Win2k3 box) where I will get a blast of NDR's all with the same subject. This last 15 -10 minutes and then stops for anywhere from a few hours to 3 days and then happens again. Thought someone was spoofing me at first but I was able to match up a lot of the outbound errors in the error log with messages getting bounced back. It appears to be sending from my mail server. I have done numerous scans with almost everyone's AV package out there (Symantec, Sophos, Kaspersky etc...) and came up with one or two little things but most were easily removed and did not appear to be of the type that would fit this kind of activity. Anyone have any thoughts on what's going on or how to isolate the issue.
