I need a tool to register incoming email messages and send a respond based on regex.<p>Example respond message: Your message received, it's id is ########<p>Can you suggest me any service or tool?
Sounds like maybe something SendGrid's inbound parser may be capable of? <a href="https://sendgrid.com/docs/Classroom/Basics/Inbound_Parse_Webhook/setting_up_the_inbound_parse_webhook.html" rel="nofollow">https://sendgrid.com/docs/Classroom/Basics/Inbound_Parse_Web...</a>
Something like procmail (<a href="https://en.wikipedia.org/wiki/Procmail" rel="nofollow">https://en.wikipedia.org/wiki/Procmail</a>) and a bit of scripting would achieve this goal.
