I'm the network/system administrator for my company with around ~17 employees. Our current email provider has been nothing but a nightmare for several years, and we're looking to switch.
We use mostly Outlook 2007, 2010, and a few 2013. As Outlook's IMAP support is "temperamental", we use primarily POP3, to download all messages to our disks.
For synchronised calendars we use a tool called 'gSyncit' to sync Google Calendar and Outlook.
We are open to utilising something else, if it proves to be "better" than gSyncit (better here meaning improved ease-of-use or improved functionality, etc.)
Therefore, here are the main requirements.
- POP3 + IMAP
- doesn't have to be large storage (per address) as we POP all messages to hard disks
- large amount of forwarding rules (to forward all mail directed at support@example to [email protected] and [email protected])
- regex filtering based on (e.g.) subject, from, to, etc.
- less than $5/per user/per month (should be cheaper than Google)
- good reliability (i'm guessing 99% up-time? I can do with less to keep costs down a little bit)
- good support (< 24h email turn around)
- calendaring (if better than gSyncit + Google Calendar solution described above)
- use our own domain name (1 at the moment, unlikely to be more in the future (you never know))
- auto-responders for vacation/holidays
- webmail (very seldom used - not a big requirement)
- iPhone + Android (mobile) access
- EDIT: unlimited (or 100+) inboxes. As these are "virtual" we do not require more hard disk storage.
What are your thoughts on the following providers?
- fastmail
- zoho
- rackspace
- atmail
OneDrive/Outlook.com for Business? From USD$2.50/User/Month with annual commitment. Sorry I have no experience but it looks quite comparable to Google Apps for enterprise if you are relying on Microsoft stack (i.e. Outlook).
