Voicemail to Email Issues


Recommended Posts

I have gone through and doublechecked all of the domain settings - but I'm still seeing a high percentage of "Last Email could not be sent"


I have removed IP's and domain names to protect the innocent:


This is log level 8 - by the way.


[8] 2008/01/22 15:46:54: SMTP: Connect to

[8] 2008/01/22 15:46:54: SMTP: Received 220 mail-02.name-services.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.3959 ready at Tue, 22 Jan 2008 13:50:39 -0800

250 OK

[8] 2008/01/22 15:46:55: SMTP: Received 501 5.5.4 Invalid Address


[5] 2008/01/22 15:46:55: SMTP Server returned 501


Is there any other indication on what the "Invalid Address" is?


On successful emails, the next thing I should see is:


[8] 2008/01/22 15:45:20: SMTP: Received 235 2.7.0 Authentication successful


[8] 2008/01/22 15:45:20: SMTP: Received 250 2.1.0 test@messaging.com....Sender OK


[8] 2008/01/22 15:45:20: SMTP: Received 250 2.1.5 joe@smith.com


So is it a problem with the sender??

Maybe it makes sense to get an Wireshark trace and see what exactly goes back and forth. What version are you running?


Additionally since you are using an exchange server, change the default logging level form none to far more and you'll have the other end of those log files. Let's all assume that in the vrtual SMTP server settings you are allowing the IP address of the PBX to send email. Additionally download one of many free SMTP email server testers and blast a few thousand emails into the server to validate it's ability to receive.
