Hi Guys,
I would like to use Sendgrid to relay all emails from the server and have followed the below
Sadly the configuration file update-exim4.conf.conf doesn’t seem to be included on loading the service and mail is still being delivered directly from the server.
I’ve been through a number of posts on the VestaCP forums which seem to refer to a different implementation of Exim.
Does anyone have this working? Thanks for your time.
I’ve figured this out for mailjet. You probably want to be editing exim4.conf.template
Under ‘begin authenticators’ I added
mailjet_login: driver = plaintext public_name = LOGIN client_send =:apiuser:apikey
Under ‘begin routers’ I added
send_via_mailjet: driver = manualroute domains = ! +local_domains transport = mailjet_smtp route_list = * in-v3.mailjet.com
// This sends all non-local domains through mailjet. You can add specific domains if you want. The route_list is the name of the mailjet server I’m sending through.
Under ‘begin transports’ I have
mailjet_smtp: driver = smtp port = 587 hosts_require_auth = * hosts_require_tls = *
That was pretty much it. Chang the port as neccessary. Put your real apiuser and apikey in between the colons
Thank you for your help.
I carried out the following to get it working with sendgrid
Under ‘begin authenticators’ I added
sendgrid_login:
driver = plaintext
public_name = LOGIN
client_send = : apikey : key
Note: username should actually be ‘apikey’, not your sendgrid username
Under ‘begin routers’ I added
send_via_sendgrid:
driver = manualroute
domains = ! +local_domains
transport = sendgrid_smtp
route_list = "* smtp.sendgrid.net::587 byname"
host_find_failed = defer
no_more
Under ‘begin transports’ I added
sendgrid_smtp:
driver = smtp
hosts = smtp.sendgrid.net
hosts_require_auth = <; $host_address
hosts_require_tls = <; $host_address
Under router configuration for alias and catchall I also changed:
redirect_router = dnslookup
to:
redirect_router = send_via_sendgridhey guys, thanks a lot for sharing, I am sure this is helpful for other community members as well!
going to add infos about using amazon SES here as well:
Under ‘begin authenticators’ I added
ses_login:
driver = plaintext
public_name = LOGIN
client_send = : user : password
Under ‘begin routers’ I added
send_via_ses:
driver = manualroute
domains = ! +local_domains
transport = ses_smtp
route_list = * email-smtp…amazonaws.com;
Under ‘begin transports’ I have
ses_smtp:
driver = smtp
port = 587
hosts_require_auth = *
hosts_require_tls = *
as one can see it’s pretty much the same, external aws guide here: https://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-email-exim.html
keep in mind that the domains usually need to be verified within your mail relay service first, also the simple configuration above is used for all domains, so if you want to have it more specific - change as needed (and maybe report back) 
So the way to limit to certain domains is under the ‘routers’ stanza.
Where you have this line saying “applies to all non local recipient domains”
domains = ! +local_domains
You can add a 'senders = ’ line to specify which sending addresses this gets applied to eg.
domains = ! +local_domains
senders = *@domain1.com : *@otherdomain.net : *@alt2domain.org1.4 will come with build in support for mail relay on user level and admin level
Just wanna share 1 more workaround which can be used for multiple domains, and will allow to use different SMTP by domain (MailJet, MailGun, SendPulse, SendGrid etc.).

Good to know:
