I have noticed that my firewall settings (proxy configuration in Network
settings) did not quite remain the same when upgrading to Tiger. You might
wish to inspect the set of network settings to make sure they¹re still what
you originally set them to be.
Expecially interesting ones are proxy servers and exceptions to the proxy
servers. Also Tiger introduces the ³exclude simple host names² setting,
which could affect you if you had set your e-mail server to be ³host²
instead of ³host.fully.qualified.domain.com².
Good luck!
