We use IIS 6.0 to send out some of our mass emails.
I noticed the queue folder is getting pretty big (2,000 emails). Some of these messages in particular need to get out today to a domain we'll call domainXYZ.com
I looked in the IIS SMTP log and it's doesn't appear as though it has attempted a connection with domainXYZ.com and yet they sit in the queue folder. I also checked the event viewer and there is nothing about domainXYZ.com
I then used telnet to connect and send a test message to domainXYZ.com and it went through ok.
I am not sure what else I can do to see what's is going on here, any ideas?
