How to connect two email address to one single Jira Service Management Project

[jeffrey.wee]

Hello, 

I have a requirements where I need to linked multiple email address to single Jira SM project. 

I had a look at the link below but it seems it is not working for me. 

https://mraddon.blog/2019/07/06/configure-more-than-one-email-channels-in-a-jira-service-desk-project/ 

What I basically have is client1support@mydomain.com (shared mailbox) support@mydomain.com (user mailbox) I have linked my support to Jira SM as I believe it does not support shared mailbox and needs to be user mailbox for me to linked it to my email channel. 

I have set auto forwarding from client1support to support and I can confirm that the emails are being forwarded. However, I only get ticket generate if I email support and not if I email client1support mailbox. 

Hopes someone could assist me on this. 

Kind Regards,
Jeffrey.
