I'd like to be able to configure OTRS ticket system to send email through sendgrid but I also want to add some configuration parameters through the X-SMTPAPI sendgrid header.
There's no obvious config setting I can see that would allow me to add a header to sent email through smtp in OTRS.
Any idea how I could do this?
A couple of notes of importance:
The server itself uses qmail, but I can't configure the entire local server to go through sendgrid because it runs some other services that shouldn't go through sendgrid
I'd like to avoid as much as possible changing the OTRS source files if possible because a) i don't know perl that well and b) that's asking for trouble
If you have a working sendmail installation, you can add the
SMART_HOST
parameter to relay all mail to sendgrid.See this SendGrid documentation for details.
