There is a serious bug in LMail 1.1a which occurs when:
 
1. A user has issued the SET PUNCH command (or it has been defaulted).
 
2. A message with lines longer than 80 is mailed to that user.
 
3. Luck causes  an uninitialized variable not to contain  what it usually
   does.
 
Delivery is aborted and no delivery error is generated. This problem will
be fixed in  1.1b, which will be  released soon. Note that the  bug is in
the  LISTSERV library  rather  than LMail,  although I  have  so far  not
managed to  reproduce it  with LISTSERV (the  routines calling  the buggy
function are few and  probably all happen to set the  variable to zero at
some point before the call). This  will be fixed with LISTSERV 1.7f. Note
that, as far as LISTSERV is concerned, this does not affect files ordered
via mail, but only those ordered  from NJE addresses with F=PUNCH, ie the
impact is very low  (which is why the bug managed to  survive such a long
time without being discovered).
