Email – Page 2

cPanel. Solving the Failed to find user “” from expanded string

Once on the same server as cPanel, after changing the settings in the WHM menu “Server Configuration” – “Settings”, email stopped working, I found the following error in the logs:

How to add DMARC record

DMARC recors allow recipients and senders to verify the authenticity of messages, as well as determine what to do with messages that are not DKIM validated.

How to add DKIM record for iRedMail

How to add MX record

I will give an example of adding MX records in the DNS settings of a domain name registrar.

Sending Asterisk voicemail to multiple emails

Let’s say the voice mail is configured as I described in the article – Setting up voicemail in Asterisk.
There is the following context:

[voicemailcontext]
207 => 1111,Username,test@example.com,,attach=yes|tz=ua|delete=yes

If you want to send a voice message to several email addresses, then instead of test@example.com, for example, testmail:

[voicemailcontext]
207 => 1111,Username,testmail,,attach=yes|tz=ua|delete=yes

Then open the /etc/aliases file in a text editor:

sudo nano /etc/aliases

And let’s specify aliases for testmail:

testmail: support@example.net,user@example.net

For the changes to take effect, you need to update the alias database with the command:

cd /etc
sudo newaliases

Done, Asterisk will send a message to testmail, and it will be automatically forwarded to the specified addresses.

Redirecting mail for the root user

Open the aliases in the text editor:

Setting the default mail address in cPanel

Suppose you want all mail that arrives at nonexistent mailboxes in your domain to be delivered to a specific mailbox.

For this:

1) On the cPanel main page, in the “Email” section, select “Default Address ”

2) In the window that opens, select the domain (if there are several), select “Forward to Email Address” and specify which address to forward.

Instead of sending it, you can also choose to delete emails, forward to a system mail account, or send to a script.

Done.
