we are running a Groupwise 2014 R2 SP1 Server. To restrict the mail traffic we are using class of service in the GWIA.
No external mail recipients are allowed except to company1.com.
These is working fine if the user is using a Groupwise mail client.
We also use for example Thunderbird or other mail clients to connect to the Groupwise Server (via IMAP and SMTP).
Here I found out that the restriction in my example above is not working.
Are the class of service not working if you are using an mail client that is connected via IMAP and SMTP?
