We have exchange 5.5 and the IMC tends to be slow in delivering messages. I noticed that the eventvwr has a strange error: Eventid 3027 The inbound SMTP queue currently exceeds 4000 items. The Internet Mail Service will not accept inbound connections until the inbound content conversion queue has dropped below 3000 items. Has anyone seen this before and how to resolve it, and why this occurs. Its the 1st time I have seen this
