You can use both PHPMail and SwiftMail to do user authenticated delivery of
email.

I highly recommend using Google Apps for business for email rather than
hoping your web service provider is keeping up on keeping their servers out
of blacklists.  The downside of Google Apps though is you do have an  hourly
throttle of, I believe, 500 emails an account for free service, and 2000 for
a paid account.

As such, doing your own internal queuing process can be useful to stay
within the throttle.

Also use subdomains to identify mail and avoid blacklists.  IE send your
automated anouncements from site.mydomain.com, send your reminders from
reminder.mydomain.com, if you ever let users forward stuff to each other,
stick that on it's own domain, relay.mydomain.com or if you give them email
accounts, members.mydomain.com

Reserve @mydomain.com for internal use only, person to person communication.

This way if any one system is subverted for a spammers purpose, your other
email continues to flow.

The free account is more than sufficient for a site that has yet to take off
commercially, by the time you hit the limits you should have a plan in place
that makes it worthwhile to spend $50/year for the business account.
