• Bug: UDP MX-Record Query

    From Digital Man@VERT to All on Thu May 13 15:10:27 2004
    Bug Report:ããI recently discovered a long standing bug in the sendmail portion of theãSyncrhonet Mail Server. Retrieiving (DNS query) of MX-records for a particularãdomain name using UDP (instead of TCP) could fail to find the MX-records andãreturn the domain portion of the destination e-mail address instead (which mayãor may not be the correct mail exchange for that domain). This problem appliesãto UDP-based MX-Record look-ups only and has been fixed for the next releaseã(v3.11c).ããWork-around:ããUse TCP DNS queries instead of UDP, by checking the "TCP" checkbox in the mailãserver configuration dialog (in SBBSCTRL-Win32), or by adding USE_TCP_DNS toãthe Options value in the [Mail] key of your Synchronet initialization fileã(ctrl/sbbs.ini).ãã digital manããSnapple "Real Fact" #88:ãA ten gallon hat holds less then one gallon of liquid.ã---ã þ Synchronet þ Vertrauen þ Home of Synchronet þ [vert/cvs/bbs].synchro.netã
