Not to obnoxiously keep posting to my own thread, and hopefully this helps someone else toying with services, but I've been tinkering with Fastmail lately on a free trial for mail only. Not sold yet, but it's actually pretty impressive. Here's why:
- Flawless push support on iOS, better than what Apple currently does with iCloud (new messages are pushed to all devices, and read/flag/pin status updates in the background when changed on webmail interface or in a mail client)
- Speedy. Delivery within seconds. Background updating as above has thus far been within a few seconds, and never more than ten seconds in limited testing.
- Extensive alias support for usernames and custom sender names for each. No autodetection of aliases (which iCloud does) within iOS/OS X, but aliases can easily be manually added on and seem to work as intended. iOS aliases cannot have custom sender names for aliases as far as I know -- something that isn't an issue with iCloud.
- Options for power users I appreciate but will never need (virtual domains, etc).
- Customizable rules on par with Outlook.com in terms of complexity.
- For those appreciative of such things, mandatory SSL/TLS, with encryption on Fastmail servers.
Still can't speak to being able to count on the service. It's basically this versus Outlook.com at this point, with a move back to Gmail a distant third.
Any Fastmail fans out there?
