My regular transnational/marketing email provider, Mandrill will be only available for paid MailChimp customer starting 27th April 2016. As I never exceed 12,000 FREE emails per month, I think there is no point to use any paid transnational services. Upon searching, I find out that Mailgun provides 10,000 FREE emails per month which should be sufficient for my use. Upon testing, the function provided by Mailgun is sufficient for my needs.
I mainly use this services because my websites utilize phpmail or sendmail function & also to send server generated message. This kind of email function many throw many emails into SPAM folder of the intended recipients. The situation become worsened if the intended recipients are using hotmail/livemail/outlook, which has stricter filtering. The recipient may not receive the email at all. Not even in Junk folder.
This is a big issue if you are running an e-commerce and even bigger issue for newsletter/mailing list website like Interspire Email Marketer.
To solve this issue, we can use transnational email or bulk email service such as Mailgun with Exim on cPanel/WHM server.
To integrate Mailgun with Exim on cPanel/WHM, we have to add proper settings as below. If you migrating from Mandrill, make sure all settings from Mandrill removed.
1. Login to WHM with a root access & browse to
WHM → Service Configuration → Exim Configuration Manager → Advanced Editor
4. Search for – “Section: AUTH” & add the following code. Change [email protected] : password with your email & Mailgun Password
mailgun_login: driver = plaintext public_name = LOGIN hide client_send = : [email protected] : password
5. Search for – “Section: ROUTERSTART” & add the following code.
mailgun: driver = manualroute domains = ! +local_domains transport = mailgun_transport route_list = "* smtp.mailgun.org::587 byname" host_find_failed = defer no_more
6. Search for – “Section: TRANSPORTSTART” & add the following code.
mailgun_transport: driver = smtp hosts = smtp.mailgun.org hosts_require_auth = smtp.mailgun.org hosts_require_tls = smtp.mailgun.org
7. Save the new configuration.
8. Send a test email & you should see the email header should have something with *mailgun.*
This will work only for one domain, how to use it for example for two domains? Mailgun have different credentials for each domain…
