>You're right and I've been working with their admin and he's tried several things and even contacted microsoft. Between them they concluded - ans passed the problem back to me - that the difference between running the app there .vs. running it here is the exchange server 2007 .vs. 2003. I had them email one of the pdf's to me and then I emailed it back to them and it went both ways. The only problem is when sending directly from my vfp app. The email itself will go but the attachment gets quarantined.


IIRC you are sending using SMTP from the VFP program. Exchange users are not using SMTP.

I think there is a difference when filtering attachments. I'm not at an Exchange 2007 server at the moment so I can't dig further, but you are using a different transport mechanism, and there are different rules applied to prevent the SMTP server from being used as a mail relay.
