Routing outgoing emails

[gesman]

Hello,

I own dedicated server: Centos 6 + WHM where i host multiple sites. Many emails are just forwarded to related gmail accounts, such as:
[email protected] -> [email protected]
[email protected] -> [email protected]

I want to route all outgoing emails (initiated via scripts on my sites, such as contact forms or password reset forms) via SendGrid/SMTP. Although I *do NOT* want to route all incoming emails (mostly incoming spam) via SendGrid.

I followed this tutorial: /http://sendgrid.com/docs/Integrate/Mail_Servers/exim.html.
But as a result of it - I have *ALL* emails (incoming and outgoing) going through SendGrid:
- Gmail is forwarding emails from paypal.com to spam folder.
- Every piece of spam is consuming my SendGrid quota now.

What do I need to change to make sure that only outgoing emails initiated by my websites go through SendGrid?

Ok, here's an answer. Took me 24 hours to dig for it.
Put this into:
WHM >> Home >> Service Configuration >> Exim Configuration Manager >> Advanced Editor
"Section: ROUTERSTART" :

send_via_sendgrid:
  driver = manualroute
  domains = ! +local_domains
  condition = ${if match_domain{$sender_address_domain}\
                 {$primary_hostname : +local_domains}\
                 {yes}{no}}
  transport = sendgrid_smtp
  route_list = "* smtp.sendgrid.net::587 byname"
  host_find_failed = defer
  no_more

This will allow you to use SendGrid only for outgoing emails originated by your website scripts, but *skip sendgrid* for all incoming emails, including emails that require subsequent forwarding outside.
Thus saving your Sendgrid quota and essentially allowing you escape dedicated server IP blacklisting/whitelisting cat-n-mouse games.

Here's what above will allow you to have:


1. Sending email to outside from any domain on your dedicated server to be routed through Sendgrid:
[email protected] --[SENDGRID SMTP]--> [email protected]

2. Contact forms and scripts from your websites will route all emails through sendgrid:
[email protected] --[SENDGRID SMTP]--> [email protected]

3. Incoming, pre-authenticated (and spam) emails processed directly, without sendgrid:
[email protected] -> [email protected] ---/*NO SENDGRID HERE*/--> [email protected]
[email protected] -> [email protected] ---/*NO SENDGRID HERE*/--> [email protected]

In latter(spam) case - email might not even reach destination due to anti-spam measures.

PS: You of course may use any other transactional email delivery service, not only SendGrid. Just change SMTP server address and credentials.

This was about the best help on this issue I've found. I was wondering if you would be willing to give a step by step to implement sendgrid. Like, I don't understand how and where to add things according to this page: https://sendgrid.com/docs/Integrate/Mail_Servers/exim.html
How and where to add this?

begin authenticators

sendgrid_login:
driver = plaintext
public_name = LOGIN
client_send = : [email protected] : YourSendGridPassword

Also, it says: Add a route in the Router Configuration Box:? Which router box? ROUTERSTART, like your instruction above?
And, it says: Add a transport to the Transport Configuration Box:? Which Transport box? TRANSPORTSTART?

Any help would be greatly appreciated.

I got this to work... the first time I edited the file at WHM >> Home >> Service Configuration >> Exim Configuration Manager >> Advanced Editor, it created the file /etc/exim.conf.local. I then just edited the file to follow the instructions at: https://sendgrid.com/docs/Integrate/Mail_Servers/exim.html#-cPanel. You should begin there.

I went to Edit MX Entry and added smtp.sendgrid.net has priority 0.

This tutorial helped: Tutorial Of Administrator: Implementing SendGrid with Exim on cPanel

I hope this helps someone.

Hi.

Is there any way to route just some domain over sendgrid?
