Overview

The setup listed below assumes you are on CentOS and clone this repo into /opt/email2sms

Change your paths to match if you don't use the same setup.

Additionally, the reply.php will need to be in a web-enabled location that Twilio can hit. However, you should not expose the entire repo to the world.

Configure your Twilio number's messaging url to the public url of your reply.php

git clone https://github.com/plabbett/email2sms

cd email2sms

composer install

Rename config.example.php to config.php Modify as you see fit.

Configure Sendmail Alias and Domain Catch All

Create alias to our script

In sendmail, add an alias to pipe email to the PHP script.

nano /etc/aliases

Add: youralias: “|/usr/bin/php –q /opt/email2sms/parse.php”

Save the file

Point catch-all to alias

nano /etc/mail/virtusertable

Add: @yourdomain.com youralias

(This hostname should be the host of the server so mail actually gets sent there)

This next configuration tells the sendmail server it can listen for messages for yourdomain.com

nano /etc/mail/local-host-names

Add: yourdomain.com

You can check /var/log/maillog for routing problems on messages.

Run the command newaliases

Restart sendmail

Navigate to parse.php and set 755 permissions:

i.e., chmod 755 /opt/email2sms/parse.php

[root@vm smrsh]# cd /opt/email2sms

[root@vm email2sms]# chmod 755 parse.php

Now we have to tell sendmail to allow smrsh to use php

[root@vm email2sms]# cd /etc/smrsh

[root@vm smrsh]# ln -s /usr/bin/php ./php

[root@vm smrsh]# ln -s /opt/email2sms/parse.php ./parse.php

You may need to perform a newaliases again and then service sendmail restart

At this point you can send an email in the following way:

Send email to <10digitphonenumber>@yourdomain.com

Example: Send an email to 5551234567@yourdomain.com

Be sure you align your directory structures with where the scripts actually are.

Environments can differ.
