Exchange on SBS 2003 will not send outgoing mail unless i stop smtp services and start again.

OK So i had an issue where a user opened up the server accidentally so that anyone could relay off it. What this did was cause thousands of spam emails appear to come from us even though it did not. I took care of that issue under virtual SMTP server.
Now they all get mail ok but Exchange will not send mail out to the rest of the world unless i either stop the SMTP service and start it again. or if i try to kill the inetinfo.exe running in the task manager. Either one seems to kick SMTP in the but and it sends all the mail but then won't send it out to the world until i do it again.
Internal email works fine from domain user to domain user.
I am running SP2 on the echange server
