Hi, I have a RedHat Linux box - Red Hat Enterprise Linux AS release 3 and have a monitoring application installed on the box. The application sends alerts to my local domain ids' . e.g : [email protected]. The problem is I do not get alerts on yahoo or gmail or hotmail account. I have checked the sendmail.cf and seems to be OK. The maillog file looks like this when sending email using sendmail -v -s commands to the [email protected] id. Apr 6 12:59:10 HOSTNAME sendmail[31882]: l36Gx9eO031882: [email protected], ctladdr=root (0/0), delay=00:00:01, xdelay=00:00:01, mailer=relay, pri=33218, relay=mailrelay.DOMAIN.com [xx.xx.xx.xx], dsn=2.0.0, stat=Sent ( <[email protected]> Queued mail for delivery). I understand that when I send a test mail from the box .. I get email on my local id and the sender name is [email protected] .. and actually it should come from a valid account id .. like [email protected]. The [email protected] is getting lost in the Interent cloud as invalid and hence cannot get emails on outside domains. PLEASE HELP ..NEED URGENT HELP.
Here is the error message : mail -v -s "testing local email" [email protected] < /dev/null Null message body; hope that's ok [email protected]...

Please check if your server is blacklisted: http://www.mxtoolbox.com/blacklists.aspx Also, do your hostname and sender domain exist in DNS?
