I'm just about to switch to Google for mail hosting, and your comment worries me a little.

What kind of trouble have people had with Google's outgoing mail servers?

I think they might just be talking about using it for mass-outbound messages from an app, not for actual human-to human messages. (Never had a problem with Gmail for my personal/work e-mail, anyway.)

You're right. We still use it for inbound, and human based outbound. We do things like send monthly reminders to pay for Tipjoy, meaning lots of emails sent regularly.

Is it possible to have multiple email providers on a single domain? How do you do that?

Does anyone else have any thoughts on the best outbound email provider to use for automatically-generated emails?
