There is no mailing list for Zinc HTTP Components, if it is not too much trouble, you can use the Pharo list which I am reading every day (see CC). > Bottom line is that I spent about a day trying to get amazon ses working > with zinc.

Indeed, when you go through stunnel, Zn will put 'localhost' in the Host: header, while AWS will be unhappy with this. It also might be important for the actual signature (I don't remember if Host: is included). Thanks for the feedback, this might safe others a lot of time ! Is your code available somewhere on SqueakSource ? I assume that you saw the 'Zinc-AWS' example that I did some time ago ? Regards, Sven
