So, anyone here administrating/deploying Google Apps for their clients? Primarily, (g)mail?
I'd like to migrate email solutions for my clients to Google Apps, but I'd like to do that with minimum hassle for the clients. Most are small businesses that really don't need Google Apps for Business, ie. have less than 10 users, and they don't use Google Docs or any of the other fancy cloud stuff provided by Apps.
So I have several options:
1. Maintain a forward only MTA and forward to their gmail accounts. Easiest to setup, but fails on SPF (my MTA IP is checked against sender domain SPF = fail). I looked into remailing but that doesn't seem like viable alternative (envelope sender rewrite with Postfix = GAH!).
2. Use Gmail's fetch mail (and maintain domain/inbox/POP3 accounts on my MTA). I'm currently using this solution, and I have a boilerplate HOW-TO guide for clients which they all seem to follow just fine. The only drawback is some complain about the delay overhead.
This option is better than, and not really the same as running my own solution because Gmail still applies superb spam filtering and web based interface (which are basically the only* reasons I'm migrating, as opposed to maintaining cpanel, webmin, whatevermin, whateverwebmail, spamninjaassassin with Bayes-whatever-imap-HAL-What-are-you-doing-Dave nightmare, etc...). Supplying a really strong POP3 password once and with SSL (for gmail -> my POP3 communication, not user -> gmail) is really much more secure than the weakest link: their own weak gmail passwords which they almost certainly reuse everywhere else.
3. Use Google Apps and with that Google's MX. Cleanest solution, but toughest to set up. I can't expect them to create their own accounts and maintain them (the google apps accounts, aside to their gmail accounts), and they're not paying me enough to do that for them (and they refuse price increase).
Thoughts? Advices?
*) EDIT: Actually the third reason is outgoing mail from my MTA still tends to end up in junkmail on Yahoo and Hotmail, even some local ISPs, in spite of the 2-year clean record (never been blacklisted) of the MTA's IP.
