How to configure Sendmail to use Aritic Mail as default relay?

Sendmail requires libsasl in order to properly send authentication requests to Aritic Mail servers. The saslauthd server daemon is not required unless you plan to receive authentication requests to the same server. For more information on configuring sendmail for SASL support, check the official documentation.

Set the authorization credentials in /etc/mail/access

We have had reports that some customers have needed to install cyrus-sasl-plain in order to avoid authentication issues as well. We have not validated this requirement, so please make sure your system administrators, Ops, and/or InfoSec people approve this change before you make it!.

 

AuthInfo:mail.ariticmail.com "U:yourUserName" "P:yourPassword" "M:PLAIN"

 

Define the Smart Host in /etc/mail/sendmail.mc You should add these lines just after the commented “#dnl define (‘SMART_HOST’, ‘smtp. your. Provider’) dnl” line in the file.

 

define(`SMART_HOST', `mail.ariticmail.com')dnl
FEATURE(`access_db')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 25')dnl
define(`ESMTP_MAILER_ARGS', `TCP $h 25')dnl

 

Update sendmail.cf and access.db files

(You will need to run these commands as ‘su’ or ‘root’)

 

$ cd /etc/mail
$ m4 sendmail.mc >sendmail.cf
$ makemap hash access < access

 

On older distros, you can run restart sendmail like so:

$ /etc/init.d/sendmail restart

If, however, you’re using a newer version, do the following to restart:

$ service sendmail restart
