[nos-bbs] Sending mail to regular addresses via Winlink

[Peter McCorison]

Users of Winlink can send email to standard non-ham internet addresses 
via Winlink. This requires modifying the delivery address. For example, 
if sending to 'name at isp.com', the address has to be changed to 
'smtp:name at isp.com'. If this address is sent from a regular email 
client, say, Thunderbird, the part 'smtp:name' will be sent as a quoted 
string ("smtp:name") in order to comply with rfc-822 addressing. This is 
correct behaviour. Unfortunately, if this quoted address is delivered to 
JNOS by smtp and sent to a winlink server, the address will not be 
recognized by the server and the message will be dropped. This problem 
comes about because the modified address required by winlink is NOT 
rfc-822 compliant.

In order to make such an address recognized by the winlink servers, it 
would be necessary to remove the double-quotes from the address. I 
suspect that the JNOS smtp server could do that with minimal 
side-effects, since the only reasonable destination for such an address 
is a winlink server.
