Hi All,
I'm currently ruinning BM38 SP4 with Mail Proxy and GroupWise 7.0.2 (latest patch), but we are having a lot of trouble getting mail out to sites running greylisting. The return message eventually comes back and simply says "Unknown User". I have changed the re-send settings in GWIA to a shorter duration, however I suspect that the BM mail proxy is not relaying back to GWIA to ask it for a re-send.

Has anybody encountered this problem?? If so, any suggestions would be greatly appreciated.
