This is kind of a repost but with fresh info:
All my post offices are 8.0.1 HP1 on Linux. Users on some post offices will not initialize and if I set the GW Connector to one of these post offices it fails to start with a POA or Trusted APP error.

I can telnet to all of my post offices on the soap port and I get expected response. BES and M+ Archive (both in soap mode) work fine on these post offices.

I'm beginning to think that it's not a soap issue but a Trusted App issue and that some of these post offices do not know about the Trusted App.

I'm going to rebuild the one of the post offices in the morning and see if that has any effect.

Any known issues related to this?
