Hi Petr,

Take a look at Horacio's work, he has gotten pretty far doing just that!
But some of the label stuff can be very slow for large volumes atm.

His gmail.rb is well-written and relatively easy to understand:

His last message to sup-devel:

Also, feel free to sign up to the devel mailing list:

or the users list, sup-talk: http://rubyforge.org/mailman/listinfo/sup-talk

Regards, Gaute
