Well, first of all the university decided to use (as a understand, without charge) gmail services, since they could not effort to run their own server. Now to the question s/mime versus gnupg. There are the following points which make s/mime easier. 1. Key generation. In s/mime you apply for a certificate and don't have to generate the key by yourself. 2. Key interchange. This is in my experience the biggest problem for most users. In s/mime it is sufficient to send a sign message, it contains the public key of the sender (I don't want now to enter the technical details) 3. Software: if you use a proper MTA s/mime is usually included, while pgp is not, but a plugin has to be installed. If the user is using gmail's webinterface, which, unfortunately more and more users are doing, things get more complicated. You mentioned mailvelop, but again this is a plugin to be installed, while now gmail (at least for its business/academic suite) offers s/mime support natively. Last but not least, a lot of people in my university now posses a first class certificate anyhow, provided by the Spanish administration, which can be used for all sort of things, one of them to use it for encrypted emails. I hope that makes it clear why s/mime is preferred of pgp. Uwe Brauer
