We have a difficulty delivering to a site running a barracuda appliance. I can email them from a gmail account, or via a telnet session, but not via postfix on our SMTP gateway. I've contacted the remote site from my gmail to discuss it but no progress so far.
I have the default pix conf settings and we are running postfix 2.8.6 In the logs we see it times out.

I wonder if the pix settings are not the right fit for this case? Is there a method to not use the pix workarounds for a single destination?
