Used Zammad version: 5.3.1-1671805004.9b7729da.xenial
Used Zammad installation type: Package
Operating system: Ubuntu 16.04.7 LTS
Browser + version: Chrome 109.0.5414.75
Mail Client: e.g. iOS 16.2 iPhone 13 Pro
Expected behavior:
Mails sent through Zammad to a customer using iOS Mail client, should be readable.
Actual behavior:
Mails sent through Zammad to a customer using iOS Mail client, can not be displayed, instead show “This message has no content”. Only Mails sent to a OFFICE365 provided account can be read in iOS Mail client.
Steps to reproduce the behavior:
Sending a Mail through Zammad to any customer that uses iOS as Mail client. Reproduced on 4 different iphones today.
The Problem still exists. Our Zammad is connected to Microsoft365 and sends the Mails through it. I updatet the whole machine and my Zammad Version is now 5.3.1-1674821848.19f3fbcd.xenial but i still have the same Problem.
