Here is the log from an example session:

I need to add logging of the sent M_FILE messages to confirm that mbcico is 
sending a 32-bit value in the M_FILE.  You can see that the remote (binkd 
1.1a-99/Linux) is sending a 64-bit value for the Unixtime in the M_GOT frame.

I suspect this is dependent on the particular Linux distribution in use and if 
the __WORDSIZE_TIME64_COMPAT32 is defined when compiling the system's glibc.

mbcico (the mailer included with MBSE BBS) rejects the M_GOT with the 64-bit 
value and ends up trying to send the file again in the next session.  I 
suspect that ifcico (which mbcico was based on) will do the same, although I 
haven't tested it yet.
