SMTP service of Windows Server 2008 not assessible, giving error: out of memory
-
I wrote a transport Sink of SMTP service, which works pretty fine in Windows server 2003. Now the server is upgraded to Windows server 2008 and I am suffering two issues: 1. The SMTP service is totally not accessible either through Outlook clinets (outlook express and outlook 2003) or telnet. While using outlook client, I created a account connecting to the server which hosts SMTP service, and I got the error "4.3.1 Out of memorry" each time I try to send a mail. While doing the telnet test, I can connect to the SMTP server successfully. "EHLO", "MAIL FROM" and "RCPT TO" commands works fine. However, when it comes to the next command "DATA", the SMTP server returns the same error as what the Outlook client got. It is said that the insufficient permisson of the "System" account in the machine where the SMTP server is hosted could cause this issue, however, I did checked that the "System" account does have the full permission against the "mailroot" folder. Anyone could help this issue, I do appreciate. 2. The SMTP sink was found no longer be able to be registered by smtpreg.vbs. I am getting the error "type mismatch". This definitely works fine in windows server 2003. Someone who knows what is going on. I do hope I can gain some help here. Appreciate any kind of help.
