Unable 2 connect 2 POP3 mail box on 2003 server

[ekuhtin]

Description: POP3 Service that comes with windows 2003 server
can't connect to mailbox!

Environment: 2003SrvEnt+POP3service installed and running...

Problem: Try as usual manual session via telnet -

<keyb> SET LOCAL_ECHO
<screen>
Microsoft Telnet>

<keyb>OPEN mypop3_2003 110
<screen>
+OK Microsoft Windows POP3 Service Version 1.0
<433423510@mypop3_2003.mydomain.com> ready.

<keyb> user mypop3_2003\prc [try here also - prc - same effect]
<screen>
+OK

<keyb> pass prc
<screen>
-ERR Logon Failure

<keyb> what the ... is going on here?
<screen>
-ERR Unacceptable command

<keyb> quit
<screen>
Connection to host lost...
UGH.............

Trying 2 of 3 modes of storing accounts - encrypted passw file & local
\\mypop3_2003 users! - same effect...

One more question, if one can advise good inet source of information 4
building some small E-Mail automatization around Microsoft Server2003
SMTP/POP3 small footprint mail system...
BizTalk&Exchange is rather hudge and complex systems to buld such solution around, from my point of view, of course...
However Exchange works well 4 our corporate mail and doc's flow for years...

Will be pleased with any advices - Eugene Kuhtin.

Welcome to Windrivers ekuhtin


So the pop server is not aware of the user mailbox or the login/pass is wrong, or there is a permission problem?

Have you tried creating a test user - are you using AD?
