Email not received through voicemail

Hello All,

I am looking for support to solve the email issue with freepbx, we recently changed our email server and the password got changed for the freepbx email account, I have updated the new password under system admin/ email setup option but we are not receiving any email when a user leaves a voicemail.

before changing the email server everything was working fine, is there anywhere else i need to update the new password in the freepbx. the version we are using is FreePBX

appreciate if someone could hep me fixing the issue.

What do you see in the mail log?

I speculate that there’s literally a TLS version requirement that is not met.

Unrelated to your issue. Consider upgrading to a supported version.


how can i check the mail log, from the web menu of asterisk logs or through the root login.

can you provide the command for that?


tail -f /var/log/maillog

You should have the correct credentials in /etc/postfix/sasl_passwd


postmap hash:/etc/postfix/sasl_passwd

and in /etc/postfix/ add at the bottom of the file

smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =

Thanks Andrew,

can you please confirm if this below config would solve the issue that emails are going out from asterisk domain com

No one can guarantee here anything, we are working/suggesting off of the logs.

So after you’ve done what Andrew had posted AND restarted postfix (service postfix restart) and it still doesn’t work, please provide the mail logs again.
