It is possible that Winlink decided it was a waste of its time to send a message right back to the station that initiated the message in the first place.? You might try sending it to one of your regular email accounts.? You must realize
that sending a message to your call sign, or your
callsign@... is the same thing.
?
If you were sending to another station, all you need to put is just the callsign with //WL2K at the beginning of the subject line.??
