AspEmail is an active server component for sending e-mail messages
using an external SMTP server in an ASP or VB environment.
AspEmail supports multiple recipients,
multiple file attachments, HTML format, embedded images and sounds,
non-US ASCII character sets, secure mail, and high-performance message queuing.
AspEmail's basic functionality, including file attachment and HTML support,
is absolutely free. Premium features
require a registration key after a 30-day evaluation period.
A copy of AspEmail can be downloaded from www.aspemail.com/download.html.

digitally signs the message to prove it really comes from the domain it claims
to have come from. DKIM is implemented by the new SendCertified method described
