Qmail and the CNAME_lookup_failed_temporarily problem [SOLVED]

Se a un certo punto il vostro MTA Qmail inizia a non mandare piu’ posta a determinati domini (di solito domini che hanno molti mx associati in round robin come per esempio: tiscali.it o hotmail.com e molti altri) e nei log del qmail-send leggete spesso errori di questo tipo:

@4000000048ec8481146ce3b4 delivery 194: deferral: CNAME_lookup_failed_temporarily._(#4.4.3)/

Allora il problema potrebbe essere dovuto a il vostro qmail-remote che manda richieste ANY al dns per trovare l’mx giusto che alla fine non trova.

Per risolvere il problema c’e’ una patch che va scaricata e applicata al sorgente di qmail in questo modo:

copiate la patch nella root directory dei sorgenti di qmail ed eseguite:

patch -p1 < any-to-cname.patch

make clean && make man && make setup check
