Outgoing mail queue slowness
We have recently installed Exchange 2013. We have noticed that with one recipient domain (wis.edu), mail just parks in the outgoing mail queue for more than an hour, then it sends. This does not happen with other recipients. Is there anything I can do to tweak the transoport service to force these emails to send quicker?

It also looks like postini is also involved.

It was really stupid. The old Cisco SMTP fixup curse. I updated the IOS configuration on the ASA with the following configuration:
no fixup protocol smtp 25
and the emails sailed out of the queue without hesitation. Thanks for your help anyway.

I checked the MX records for both sites and the common thread is that google mail servers are involved on both sites:
Here's oneumd.org:
oneumd.org MX preference = 30, mail exchanger = aspmx2.googlemail.com
oneumd.org MX preference = 30, mail exchanger = aspmx5.googlemail.com
oneumd.org MX preference = 20, mail exchanger = alt1.aspmx.l.google.com
oneumd.org MX preference = 10, mail exchanger = aspmx.l.google.com
oneumd.org MX preference = 30, mail exchanger = aspmx4.googlemail.com
oneumd.org MX preference = 20, mail exchanger = alt2.aspmx.l.google.com
oneumd.org MX preference = 30, mail exchanger = aspmx3.googlemail.com
aspmx2.googlemail.com internet address = 173.194.67.27
