I'm having the same problem too. Can't send to my corporate network.

From: [email address]

The following message to <user@domain.com> was undeliverable. The reason for the problem:
5.1.0 - Unknown address error 550-'<me@domain.com>: Sender address rejected: Blocked'

Anyone know how we can fix this?

Thanks,
Cindy
