in [Sendmail]

From: pierre on 7 Feb 2007 10:54 Hi, I try to use sendmail on a new fedora core 6 installation and I got a "host name lookup failure". It is impossible to have the smtp server down so I don't understand the message and what happends. Any Idea ?

Deferred: Name server: smtp.free.fr: host > name lookup failure It seems that you have problems with AAAA lookups. Add WorkAroundBrokenAAAA to your sendmail configuration. The details has been posted *many* times in the grroup => search archives. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)priv.onet.pl : anfi(a)xl.wp.pl Before You Ask: http://anfi.homeunix.net/sendmail/B4UAsk-Sendmail.html http://anfi.homeunix.net/sendmail/ [orkut,linkedin,xing]
From: pierre on 7 Feb 2007 14:46 Hi, I've done what Filip propose by putting the information in submit.mc and then rebuilt it (m4 submit.mc). [root(a)calais mail]# more submit.cf | grep AAA O ResolverOptions=WorkAroundBrokenAAAA This still does not works for me : [root(a)calais mail]# sendmail -v -d8.20 -q Running /var/spool/mqueue/l17GngnY005124 (sequence 1 of 3) dns_getcanonname(tireme.net, trymx=1) dns_getcanonname: trying tireme.net.
