RE: FN-FORUM: Advice for bulk emailing

Depends how it's written. Our mail handler works by creating entries =
into a DB table and using Jmail to send out individual emails - so =
they're all "proper To", not BCC. If Jmail generates an error whilst =
sending we can flag the message for resending or indicate that the email =
address may be duff or that there is an issue. We could then go one step =
futher and have a return address for bounced mail from the server, use =
scheduled Jmail to check a pop3 box to mark off mail that's bounced.
There are also .NET components available (see ASP.NET) that can validate =
mail by checking domains & MX records before sending mail.
But as you say, it all costs.

web based send methods are not relaible at all there is no guarantee any =
