I have one non fidonet aka setup and AS/mac is tossing mail ok. However the AKA is wrong on outgoing packets and BBBS is barking at them:

260921 18:37 Processing packet 6b530005.pkt from 2:263/1.5, 630 bytes.
260921 18:37 Invalid destination: 2:263/1.5 -> 618:263/1.0 in MIN_CHAT.

I know you have not started work on multi akas so please take your time wit it. Maybe it would be better to have the origin aka in the echo settings
