 Hi,

 I am working on an email client. One of the (side) goals is to provide
 robust access to things like riseup.net, which means providing IMAP and
 SMTP/Submit access via Tor (and also doing some things to prevent
 information leakage).

 The IMAP bits work well: I can access riseup via Tor with excellent
 performance, thanks to a little prefetching and so on. I also don't leak
 information. But I cannot send mail at all, in any way. AFAICT, it seems
 to be mostly a side effect: Tor blocks access to port 25 to combat spam
 and abuse, and ports 465/587 were blocked as part of the same change.

 I find that very unfortunate. Blocking 465/587 means that there is no way
 to write a proper privacy-guarding email client using the IETF protocols.
 Please reconsider that.
