Comment(by psmith2100):

 It looks to me that the 2.7.0 and later are trying to send non HTTP
 traffic through the HTTP proxy and that is why the content filters are
 denying the traffic and asking for authentication.

 > 2.7.2 did not work but I think I see the problem.  I have attached three
 files.  I have attached debug2.7.2.txt and 2.7.2.cap and 2.6.6.cap.  The
 "cap" files are sniffer traces.  Download Wireshark www.wireshark.org to
 view the sniffer files.
 >
 > 2.7.2 is sending traffic through our HTTP proxy that is not permitted by
 content filters and that is why we see the authentication required message
 in the debug and in the 2.7.2.cap file.  2.7.2 contacts the HTTP proxy
 first instead of contacting the IM account proxy first.
 >
 > However, you can see in the 2.6.6.cap file that 2.6.6 contacts the IM
 account proxy first and a significant amount of traffic goes to the IM
 proxy before the HTTP proxy is ever used.  The HTTP proxy is first
 contacted at line 17, and line 20 is the first HTTPS traffic ever sent and
 it goes to login.yahoo.com:443.
 >
 > Keep in mind that these sniffer traces are just between my PC and the
 proxy servers and do not include traffic between the proxy servers and
 Yahoo, so I assume the IM proxy is communicating with Yahoo on port 5050
 as indicated in line 11 of 2.6.6.cap which is the port in the account
 settings.
 >
 > So it appears the issue is that releases later than 2.6.6 are not
 sending the appropriate traffic to the IM proxy and are sending it to the
 main HTTP proxy.

 staring at the code in question.  I'm not sure I've fixed the problem in
 any way, since I don't have proxy servers to test with, but at the very
 least, the fallback mechanism referenced two comments ago should kick in
 and attempt a connection if all else fails.

 .2devel-offline.exe the 2.7.2devel installer] again and test it.  I have
 rebuilt the installer to include the fixes described in the previous two
 comments.  Again, it's an offline installer that includes everything
 except spell checking dictionaries.
