Well, the error message said "temporary" failure, with a "deferred" status of the queue. Once the problem goes away, it can retry. Or may just keep retrying, anyway. The obvious question occurs: Had you restarted the mailserver during these tests? You usually have to restart servers when you make configuration changes, and sometimes when networks go up and down. I still don't get an answer if I try a reverse lookup on the IP. Perhaps other servers can do it (i.e. the record's there, but hasn't appeared in the servers that I'm querying). -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
