I checked in Hub transport: if the recipient is not part of our global address list then reject those mails in hub transport still we are receiving emails with fake emailid's like: hgf2345@domainname.com and this email id is using our domains email address which is not part of our organization, like these we are getting every single day. Thank you very much for the helpful info

I saw Tim Harrington's post and agree completely with him. You need to step back and purchase a proper solution. You have already wasted more money in your own man-hours putting in little tweaks and workarounds than you would have done if you had just bought and implemented a product. As for your problem you describe below, kick start it by restarting the Transport service. "cplusplus1" wrote in message news:5f4b3b83-2d7c-40c3-8b02-4eeed2035f49...
