UBQ000069:  Troubleshooting SMTP

UBQ ID Number: UBQ000069
Last Modified: 2005-09-13

Summary:

UltraBac has the ability to use SMTP notification using any local / remote SMTP server.

Details:

The "From" and "To" e-mail addresses must be of a proper form (example: something@something.something). test@asdf is not of valid form because it doesn't contain a period or top level domain. Additionally, if relaying is prohibited on the target SMTP server, and/or only certain users are allowed to use the SMTP server, then it may be necessary to provide a legitimate e-mail address in the "From" and "To" fields.

 

SMTP TROUBLESHOOTING SCRIPT

Use the following script to test SMTP. Type only the bold text:

 

C:\>telnet mail.mailserver.com 25

Trying 207.149.155.154...

Escape character is '^]'.

ERROR WSA 10060

Q. Why do I receive an error like: "SMTP error connecting to SMTP server WSA 10060"?

 

A. The connection may be timing out due to a slow link. Increase the retransmission timeout value of the following registry key to 10 or even 20.

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\TcpMaxDataRetransmissions

 

More about this registry key is found in Microsoft's Q191143 article. For information:
