Yes, as far as Linux/Nagios is concerned they are standard messages to SMTP addresses. >Have you verified that sendmail is behaving itself as a normal mail server on the Internet? It has valid public reverse DNS? Forward DNS matches reverse DNS? HELO name is a valid FQDN, preferably matching reverse DNS for the IP? What do your sendmail logs show? Is there a bounce generated? We use the same Nagios command to send successfully to the SMS addresses (number@vtext.com vs number@vzwpix.com for MMS) of the same phones (i.e. using the same SMTP servers to get out). The sendmail logs show the messages as being delivered Okay. I did some testing, I'm trying different things to try and discover where the problem lies. Test: Send 10 messages from old RH/sendmail box to MMS address of cell phone, Send 10 messages from new RH/sendmail box to MMS address of cell phone, Send 10 messages from windows box (with sendmail port) to the MMS address of cell phone. All messages are sent one after another from the command line. Results: Usually all 10 of the messages from the Windows box come through, though not always. Some of the Linux generated messages come through I've gotten as many as 4 and as few as none. The new versus old versions of Linux and Sendmail do not seem to make a difference. The messages will come through on occasion but not consistently. Not good for a monitoring solution. I should rephrase my original questions: Is anyone else using MMS to receive Nagios alerts? Do you ever notice any alerts not getting to your phone? What provider are you using? Thanks, -greg </BODY> </HTML>
