Voicemail is not sent to email

Please check if e-mail address is correct in "Email:" field in user Device settings.

Also make sure that mails are not in a Spam folder.

Make sure Postfix service is not stopped and starts with reboot:

[root@mail3 log]# chkconfig postfix --list
postfix         0:off   1:off   2:on    3:off   4:on    5:on    6:off
(in this example configuration is broken)

Check /var/log/maillog for more clues.

Example

Dec 12 20:42:51 localhost postfix/smtp[28599]: connect to alt3.gmail-smtp-in.l.google.com[209.85.225.26]: Connection timed out (port 25)

Message shows that mail server cannot be connected.

Voicemail is not sent to Google mail (Gmail)

If you see such errors:

550-5.7.1 [2a01:4f8:160:726d::2] Our system has detected that this message does
550-5.7.1 not meet IPv6 sending guidelines regarding PTR records and
550-5.7.1 authentication. Please review
550-5.7.1  https://support.google.com/mail/?p=IPv6AuthError for more information
550 5.7.1 . e138si7186453wmf.124 - gsmtp

You can make tcpdump on port 25 to make sure that IPv6 is used:

tcpdump port 25

If IPv6 is used, then output should be similar to this:

12:54:36.268451 IP6 CentOS-65-64-minimal.44712 > 2a00:1450:4013:c02::1b.smtp: Flags [.], ack 1, win 113, options [nop,nop,TS val 2049592501 ecr 2609461210], length 0

To fix this, please edit file:

/etc/postfix/main.cf

Change:

inet_protocols = all

To:

inet_protocols = ipv4

And restart Postfix:

/sbin/service postfix restart
