Single SMTP config for all outbound emails

Infos:

• Used Zammad version: 6.3.1-1717572987.fd8871d4.focal
• Used Zammad installation type: package
• Operating system: Ubuntu 20.04.6
• Browser + version: Any

Expected behavior:

• I would like to have a single SMTP configuration for outbound emails, regardless of which channel the ticket came in from.

Actual behavior:

• The outbound SMTP server is selected depending on the incoming channel. In my case, if a ticket was created from the Microsoft 365 channel, Microsoft 365 SMTP is used to send emails. This is the behavior I would like to avoid.

Steps to reproduce the behavior:

• I have both an Email channel and a Microsoft 365 channel.
• If a ticket is created from the Microsoft 365 channel, the Microsoft 365 SMTP settings are used for any responses.
