I came across a problem related to sending e-mail in a BlueDragon.NET beta 7 environment. Whenever I tried running a cfmail function, the e-mail file would be dropped to the undelivered BD directory and the following SMTP server error message would be appended to the mail.log file under < BlueDragon website folder >\work\cfmail:

Sender John Smith was rejected: 501 - [501 5.5.4 Invalid Address]

This issue disappeared after taking out the name bit and leaving a pure e-mail address in the cfmail "to" and "from" attributes. So, this WOULD work:

...whereas this WOULD NOT:

According to Microsoft, such problems occur when you have a UNIX mail server - Exchange Server 2003 relation (see: http://support.microsoft.com/?id=291828 ). The above example proves such an issue can also occur between BlueDragon acting as a mail sender and a standard, Windows 2003 SMTP server.
