2.5.3 SMTP service crashing
The HP ePrint Enterprise SMTP sink component receives email messages that will be printed. It runs as a
plug-in to the SMTP service.
If the SMTP sink component fails to process the message (runtime errors), it may start a loop to process the
message again, leading to exhaustive system resource usage.
If this occurs, complete the following steps:
1. Stop the SMTP service.
2. Go to the folder where messages are located (usually C:\inetpub\mailroot\Queue).
3. Remove all .eml files from folder, and send it to the HP ePrint Enterprise support team to be
investigated.
Restart the SMTP service.
2.5.4 HP ePrint Enterprise fails to send any emails
This problem can occur when there is an authentication issue between the ePrint server and the Exchange
server when using Exchange Server 2007.
First, start with a new custom receive connector. (Think of receive connectors as protocol listeners. The
closest equivalent to Exchange 2003 is an SMTP Virtual Server. A new one must be created, as you will want
to scope the remote IP Address(es) that you will allow.)
Figure 2-31 New SMTP Receive Connector
Pay particular attention to the Remote Network settings screen. This is where you will specify the IP ranges
of servers that will be allowed to submit mail. Add the IP’s of all the ePrint Servers (Primary as well as
Secondary instances).
