Follow-up Comment #7, sr #106478 (project administration): Most probably this is due to DNS mismatch:
$ dig -t MX pittle.org mx.pittle.org. 1592 IN A 65.254.254.52 mx.pittle.org. 1592 IN A 65.254.254.50 mx.pittle.org. 1592 IN A 65.254.254.51 $ dig -x 65.254.254.50 50.254.254.65.in-addr.arpa. 3320 IN PTR mail.yourhostingaccount.com $ dig -t MX gnu.org mx10.gnu.org. 300 IN A 199.232.76.166 mx20.gnu.org. 300 IN A 199.232.41.8 $ dig -x 199.232.76.166 rev-c76-166.gnu.org. 300 IN PTR mx10.gnu.org. You should check/fix the DNS records of pittle.org. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/support/?106478> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
