Yes. In my .mc I have tried
define(`confBIND_OPTS', `+WorkAroundBrokenAAAA')dnl
and
define(`confBIND_OPTS', `WorkAroundBrokenAAAA')dnl
and I have had for some time,
SENDMAIL_CFLAGS=-D_FFR_WORKAROUND_BROKEN_NAMESERVERS
in my /etc/make.conf
still,
smtp1# !mail
mail -v postmaster@ica.net
Subject: test
EOT
postmaster@ica.net... Connecting to icamail.ica.net. via esmtp...
postmaster@ica.net... Connecting to mail6.ica.net. via esmtp...
postmaster@ica.net... Deferred: Operation timed out with mail6.ica.net.
smtp1#
I also rebuilt it just to make sure the flags were being passed and it
seems to be
cc -O -pipe -I/usr/src/usr.sbin/sendmail/../../contrib/sendmail/src
-I/usr/src/usr.sbin/sendmail/../../contrib/sendmail/include -DNEWDB -DNIS
-DNETINET6 -DTCPWRAPPERS -DMAP_REGEX -DSTARTTLS -D_FFR_TLS_O_T -D_FFR_TLS_1
-D_FFR_TLS_TOREK -D_FFR_WORKAROUND_BROKEN_NAMESERVERS -c
/usr/src/usr.sbin/sendmail/../../contrib/sendmail/src/udb.c
Also, where is it described in the README ?
