We have SharePoint Portal Server 2003 implemented with service pack 2 using SQL Server 2000 with Service pack 4 on the same machine, we use both Portal areas and SharePoint sites, we do receive alert emails when there is an alert generated on SharePoint Sites, but when it comes to Portal the My Alert Web part is updated showing the recent updates on the alerts which we subscribed to but we don’t receive emails for those alerts. I don’t get it, I did a lot of research work found so many things, tried so many things as well but haven’t been able to fix this thing, alerts are a very important part of our business processes which has been implemented on SharePoint.
