rsmpt.txt Modified RSMTP.C so that any substring of the full host name will match. I.E.: valid substrings of shop-pdp.kent.edu shop-pdp shop-pdp.kent shop-pdp.kent.edu etc... This fixes a mail delivery failure on the local subnet if the mail destination was specified only by the machine name. Change at line 695 of RSMTP.C: from: !strneq(t+1,q,strlen(q)) to: strncmp(t+1,q,u-(t+1))
