Add Fastwebnet provider

[skariko]

I have tried @fastwebnet.it (an italian provider) and it works all like a charm.

Domain(s): fastwebnet.it

Website of provider: fastweb.it

Does it work without Preparations? OK!

It works with no problem at first attempt.

Do you know which servers the provider uses?

imap-server: imap.fastwebnet.it
imap-port: 993
imap-security-socket: SSL/TLS

smtp-server: smtp.fastwebnet.it
smtp-port: 465
smtp-security-socket: SSL/TLS

[r10s]

closing stale issue, the information may be outdated, also very likely it will work without any special settings.

in general, better create a PR directly for missing providers.
