Transport Problem - 4.May2009 11:25:53 PM

I have a Single CAS/HUB Transport server in my domain and all of a sudden no internet mail is being sent or recieved.  I just finished with a Notes to Exchange 2007 SP1 conversion about a month ago so our Notes server is still acting as a smart host for the Exchange server.  Naturally I rebooted everything and verified all in place credentials were valid/not locked out etc.  Plenty of diskspace and RAM are available etc.  When I look at the console of the Notes server I see a ton of messages being sent to hinet.net and yahoo.com.tw domains.  It is clearly SPAM.  I have scanned and re scanned my servers for virsuses/malware etc. and they are all clean. 

I have ticket open with Microsoft but does anyone here have any ideas.

Isn't it possible that your server act as open relay? If so you might be blacklisted, which doesn't explain why you can't receive but that could make up for the sending!
