TITLE:

Disabled Mail Service gets reenabled on service plan changes​

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:

Plesk Onyx 17.5 Update #35, Ubuntu 16.04.3​

PROBLEM DESCRIPTION:

When saving a service plan and it synchronizes, it reenables Mail Service on all unlocked subscriptions that manually disabled it.
This is unforutnate, because the service had been disabled on purpose, as the subscriptions use external mail services.
Reenabling the service means that every domain on the server will not deliver mail correctly anymore to the affected domains.​

STEPS TO REPRODUCE:

1. Choose an unlocked subscription
2. Disable the Mail Service
3. The subscription remains unlocked
4. Make a change in the service plan, Apply & Sync

ACTUAL RESULT:

The mail service gets reenabled​

EXPECTED RESULT:

The mail service should remain disabled​

ANY ADDITIONAL INFORMATION:

I tried to reproduce by creating a new service plan with default values and a new subscription, and indeed the mail service remains off.
However, it happens with my existing subscriptions... I will try to find out what triggers the behavior...
