I have had an mail.com account for several years, because google.com is banned in China but this works. Chose an 'email.com' moniker as it is easy for everyone to remember, although often get asked if I really meant 'gmail.com'. But have not had any problems so far, works like any other email as far as I can tell.
Oh, one gripe is that my emails often end up in the receivers spam / junk mailbox so other servers obviously don't recognise it sometimes. Don't know what I can do about that, but then I have never tried to.

P. S@ Devan N. Hasn't happened yet and I / they have sorted the junk email problem - seems they were marking my emails as spam because I use a VPN [being in China] and my IP address kept changing. They have since white-listed me and no problem since.
