Since lavabit.com went down, I have been looking for a substitute: a mail provider with

• anonymous set-up process
• IMAP support
• SSL support
• free of cost

hushmail.com reserves IMAP access to paying customers. With safe-mail.net it is the other way around: SMTP access is reserved to paying customers, IMAP is not. So it is a good fit for receiving notifications from a website that you would rather not use your _first_ @ _family_.org style address with. While safe-mail.net docs mention www.safe-mail.net for SMTP, IMAP, POP consistently. With Thunderbird you get no helpful error, but a raw IMAP test login helps:

# openssl s_client -connect www.safe-mail.net:993
CONNECTED(00000003)
[..]
* OK IMAP4 on tapuz.safe-mail.net at ??? ??? ?? ??:??:?? 2013
foo LOGIN ???????@Safe-mail.net ????????????
foo NO LOGIN failed. (Please change incoming and outgoing server
     from www.Safe-mail.net to tamar.Safe-mail.net)
DONE

So tamar.safe-mail.net it is. Okay...
