I have a strange problem with outgoing alerts e-mails on our SP 2010 farm. Alert notification are delivered, but no alerts comes whatever I do. I remembered the page for SP alerts here and followed the instructions, but with any luck...
Nothing was changed on Exchange or Configure outgoing e-mail settings in CA, server was restarted three times, no errors in log, Immediate Alerts job works (end with succeeded status every 5 minutes), owstimer is healthy and telnet SMTP test was successful.
There is one strange thing. I wanted to check if exist some aletrs waiting to be send on disk in inetpub folder, but I cannot find any. Where are they? Yes, there is chance, that we lost them... Beside that, there is no our-portal.domain folder, only old one with different DNS name and yes, we changed DNS names three days ago.
