Hello. We want to send Mautic e-mails through a SMTP relay service that requires messages to have the custom SMTP header X-Strrelay with a certain value. We haven’t found this in the e-mail settings. Are we missing something, or this cannot be done without creating a plugin?  
  
  
  
Thanks in advance.

_ **Mautic can do anything.** _

You’ll find this here:

Channel -\> Email -\> Advanced tab -\> Click on the orange **Add value** button

Hello,

how can we do to set customs header programmatically from code in mautic 3.3.3 ?  
I want to automatically define headers when creating a new email to a segment.

Thanks,
