AFAIK that's simply not possible. Proxying that is not transparent is 
only (for practical matters, there might be esoteric protocols that do 
that as well) defined for HTTP. So "I need to direct all non-HTTP 
traffic through a proxy server." does not make much sense - at least to me.


In other words: there is no such thing as general proxying, and thus no 
support in any library e.g. imaplib or such.

Do you have an example of an application (e.g. mailclient or such) that 
*does* support the above scenario?
