The easiest way to solve this is to set up your email client at work to
use the SMTP server supplied by your DSL supplier.  You can still leave
your from id as bdowd at dentfirst.com.  What's happening is that your
ISP's SMTP server won't relay outgoing mail unless it's from an IP
address within their network.  Getting them to reconfigure to relay
outgoing mail from SpeakEasy probably won't be easy, as it opens them to
spammers using SpeakEasy using them for a relay.  Instead, use
SpeakEasy's SMTP server, and just leave your from address as
bdowd at dentfirst.com.  Relay-denying is normally based on the ip address
of the client, not on the from-address, as the from-address is too easy
to spoof.
