2096.0. "POP3 Teamlinks 2.7 and Firewall" by KERNEL::ANDERSONL () Tue Apr 01 1997 09:20

    Hi 
    
    I have the following customer problem with POP3, Teamlinks 2.7 and
    Firewall name limitations
    
    Problem Description:
    
    I am trying to connect my Teamlinks 2.7 to a pop3 server. The problem
    is getting past our firewall. We currently have a seal firewall gateway
    from yourselves. It is called GCSIN3.GECCS.GECM.COM and when I try to
    connect to POP3.DEMON.CO.UK@GCSIN3.GECCS.GECM.COM it complains that the 
    server name is longer than 32 characters.
    
    Can you give me guidance as to how to navigate my firewall.  My
    firewall expert was asking questions about proxies and logging on to the
    firewall before connecting to the outside world, but I could not find 
    anything in the manual about proxy logons for POP servers.
    
    
    Can anyone tell me (as I can't find any documentation on this) is the
    customer doing something wrong?..  Is this a Teamlinks restriction or
    is it an IP or Firewall problem
    
    Any pointers would be greatly appreciated
    
    Thanks

2096.1Some workaroundsTAMARA::laceup.zko.dec.com::tamara::fitzellIt's not a bug it's functionally challenged !Tue Apr 01 1997 17:4314
Lynn,
	The 32 char limit is a TeamLinks imposed limitation but 
there are some ways around it. The first two probably won't help 
since you're going thru a gateway but I'll put them here for 
completeness. One way it to not use the full name. My local ISP 
wouldn't work with reg.bah.nh.us it only works with reg as the 
server name. Another way would be to use the TCP address ie 
20.24.32.10. The last and probably most likely to work in your 
case is to go into office.ini and change the server field in the 
[POP3] section to whatever you need. Just don't modify that field 
in the UI when a connect box POPs up or you'll get what you're 
seeing today.

One problem is the Server name member in the CONNECTINFO data structure
is limited to 32 characters.  This is the Server field in the TL Login 
dialog box displayed by the Connect.dll.  I wanted to fix this in 2.7, 
but was told not to.  There is no way to increase this without breaking
lots of applications.

See if the work-around Mike gave you works.

2096.3Proxy Server?...KERNEL::ANDERSONLFri Apr 04 1997 12:3615
    Hi,
    
    thanks for the responses.
    
    The customer has tried the office.ini workaround but is still not
    having any success.  He has been talking the firewall technicians they
    say that for ftp and telnet connections they have a proxy server which
    you connect to then you connect to destination.  They can telnet to pop3
    server and it responded so I guess the question now is are we missing
    something in the setups that would allow teamlinks to pass thru the
    firewall
    
    Thanks

Lynn,
	Seeing how this is a customer and it's a new and interesting 
problem I think you should IPMT it. Right now I have a lot more questions 
than answers. 

First what flavor of Windows are they using and what TCP/IP stack? 

Can you have the customer turn on POP3 logging and post the logfile so I 
can see what if anything happened when the office.ini workaround is tried.

Now If I understand this correctly they first have to connect to the proxy 
server then they make the telnet or ftp connections. Do they just go into 
to telnet and put in   POP3.DEMON.CO.UK@GCSIN3.GECCS.GECM.COM and it all 
magically happens or do they make a connection to the proxy server then gp 
into telnet?

Have they tried another any other POP3 clients like Eudora?
