[imp] Can a firewall cause a timeout for sending mail?

[Bill Graham]

My firewall has nothing specific to horde/imp in it
ports 80 and 443 that's it

There have been problems with IE being broken with ssl

This fix was posted on the list


-----   from list  ----------------------
In this case it's not a Horde problem - it turns out (assuming nobody
calls in the next few minutes to tell me it ISN'T fixed)  that the
problem is indeed with (surprise surprise) MICROSOFT.  It's, I'm
told, a bug in the way IE handles SSL.  To fix it I added the
following to my httpd.conf file...

In the VirtualHost section for port 443:

SetEnvIf User-Agent ".*MSIE.*" \
          nokeepalive ssl-unclean-shutdown \
          downgrade-1.0 force-response-1.0


SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP

(note all that's changed here is we're not allowing Export56..)

---------------   End of From list -----------------------


You can search for
Problem with SSL and compose

on the imp list for more details

Hope this helps or at leasts gives you a clue
