Hi - this may be kind of a bizarre question but here goes…
I’ve been using Asterisk/Trixbox for some time now. I’ve always used the e-mail notification feature when a new message is left for a voice mail user with no problems.
Recently, we’ve changed our ISP to Comcast high speed cable with no problems except one…
It seems that no e-mail notifications are being sent out anymore or if they are, Comcast mail servers are rejecting them. We use Microsoft Small Business Server 2003 and here is what I have discovered.
I have my exchange server connected directly to the Comcast Cable modem so that outgoing/incoming e-mails (to server users) are sent via DNS. The Trixbox is installed behind the server but has it’s own private IP address, i.e. 192.168.2.10. I have configured the Nameserver in Trixbox to match the Comcast DNS and have tried other variations as well.
After doing a lot of testing with sending test e-mails to myself, here is what I’ve found:
Comcast will not allow me to relay emails directly from their Cable modem connection to other Comcast users. I get a rejection e-mail stating this.
I have tested sending an e-mail from my SMall Business Server e-mail account to another Comcast user and it was returned. For whatever reason, I cannot send e-mails (via Server or otherwise) directly via DNS. However, when I re-configure my Small Business Server to direct outgoing e-mails to Comcasts mail server, i.e. smtp.comcast.net, everything goes through fine with no probelms.
I believe this is the problem I"m having with Trixbox and why it is not sending voice mail notifications. Does anyone know how I can re-configure SENDMAIL (or whatever application is responsible for sending e-mails outbound) to relay outgoing e-mails to smtp.comcast.net as opposed to sending out via DNS???
Thanks for any help you can give…
