Elastix Voicemail to Email not working

Elastix Voicemail to Email not working

I was trying to configure my Elastix voicemail to send voicemail on Email. but the email was not being delivered to the  my email address. I had configured properly my remote SMTP under mail configuration. I was able to send email from my elastix mail system and emails was being delivered to my email address.

But  Voice mail was not being delivered to users email address.

I started troubleshooting I checked the log

tail -f /var/log/maillog

I found below error message

Apr 16 01:29:26 localhost postfix/qmgr[1820]: 6B600C90A91: from=<asterisk@pockw.localdomain>, size=813, nrcpt=1 (queue active)

The problem was asterisk@pockw.localdomain  which was sending voicemail to email it was not a proper email address and it was not being resolved by the DNS server as pockw.localdomain  was my server host name .

I found below article 


As it says
in freepbx gui set serveremail in voicemail admin > settings to noreply@mydomainname.com

Above point I did not find in freepbx setting so I left that. and followed the next point.

edited /etc/postfix/main.cf
a. uncommented mydomain paramater in INTERNET HOST AND DOMAIN NAMES section
b. set mydomain = mydomainname.com
service postfix restart
accounts set to email voicemails as attachments are now receiving emails from noreply@mydomainname.com

Is it a bug that the postfix setting has to be manually changed?

Thats work for me it just changed the sender email address from asterisk@pockw.localdomain to asterisk@pockw.gkhan.in  but still mail was not being delivered.

Now I was getting below messge.

Apr 16 02:18:24 localhost postfix/cleanup[2354]: 143F1C90A91: message-id=<Asterisk-6-1160313698-111-2974@pockw>

Apr 16 02:18:47 localhost postfix/qmgr[2228]: 37D98C90A92: from=<>, size=2515, nrcpt=1 (queue active)
Apr 16 02:18:47 localhost postfix/bounce[2359]: 143F1C90A91: sender non-delivery notification: 37D98C90A92

To resolve the issue I did the following .

I created a sub domain pockw.gkhan.in  and created a mx record pointed to gkhan.in mx record and created a email id user under  pockw.gkhan.in  as   asterisk@pockw.gkhan.in  .

Note :- All above i did it on my  Domain Cpanel .

Now the mails was being delivered successfully.

Apr 16 20:34:56 localhost postfix/cleanup[7935]: 66C17C90A91: message-id=<Asterisk-9-1233714121-111-2974@pockw>

Apr 16 20:35:21 localhost postfix/qmgr[2228]: 66C17C90A91: removed

Now It was working fine and voicemail was being delivered to users email address.


I got good solution from below link on comment of Billsion . postfix-masquerade.


you can masquerade the sender email address to the real one which you want .which will accepted by the you SMTP server .



Postfix MTA offers smtp_generic_maps parameter. You can specify lookup tables that replace local mail addresses by valid Internet addresses when mail leaves the machine via SMTP.

Open your main.cf file
# vi /etc/postfix/main.cf

Append following parameter
smtp_generic_maps = hash:/etc/postfix/generic

Save and close the file. Open /etc/postfix/generic file:
# vi /etc/postfix/generic

Make sure tom-01@server01.hosting.com change to tom@domain.com
tom-01@server01.hosting.com tom@domain.com

Save and close the file. Create or update generic postfix table:
# postmap /etc/postfix/generic

Restart postfix:
# /etc/init.d/postfix restart

When mail is sent to a remote host via SMTP this replaces tom-01@server01.hosting.com by tom@domain.com mail address. You can use this trick to replace address with your ISP address if you are connected via local SMTP.


I check with my PBX its working fine.
