email-spam

We have an app that allows users to send e-mails from our system. It allows the user to specify their e-mail address, and gives them several standard templates to use as a starting point for their e-mail.

When we send the e-mails, we use the address they provided as the 'reply-to', but the 'from' address of the e-mail (naturally) looks like our system (from '[email protected]').

Is there a way to change this without getting tangled up in spam filters or automatic blocking? We'd prefer not to confuse the recipient as to who actually composed the e-mail they've received.

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
