I have an ASP website on an IIS server, yesterday I noticed that this certain website was unable to send out any emails as Dynumail (something we use for SMTP emails in code) could not connect to the SMTP host.
This issue was only happening with this website and not any of the others on the same server that also use Dynumail.
Is there a way to track how this might have happened? To resolve the issue I restarted the website through the IIS GUI.
Any help on tracking down (and preventing) this issue would be greatly appreciated!
