My clients use SMTP AUTH, or (if they either have an old mail client, or 
don't have AUTH configured) use smtp-after-POP. Both work well. The SMTP 
AUTH implementation in sendmail 8.11.x works flawlessly, as does the TLS 
implementation, which we also support and use. Outlook and Outlook Express 
support SMTP AUTH with no problems whatsoever. Their TLS implementation has 
some issues.

Eudora 5.1 has the cleanest implementation of TLS and SMTP AUTH I've seen 
anywhere. They've done a great job with the implementation. Same goes for 
Qpopper 4.0, which is easy to work with, and supports TLS well.

We do email hosting, but provide no access services. All of our users 
connect to our mail servers remotely. We've never run an open relay, and 
our customers have full access to use our SMTP and POP services. It really 
is possible to do all of this, be successful and have happy customers.
