synapse: add mail config (currently broken)

tl;dr: mail config works, but on trying to send mail synapse gets rejected by
postfix for using a too-old version of tls, as apparently tls in twisted (the
python library used for mail in synapse) is just hardcoded to v1, which our
postfix rejects.

```
postfix/smtpd[9737]: warning: TLS library problem: error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol:ssl/statem/statem_srvr.c:1685:

```

This is a known issue [1], which should be fixed in the current version of twisted,
which will be in the next version of synapse.
