I have mailcow setup as an smtp relay, where different domains assigned different sender dependent transport.
All the sender dependent transport/ SMTP relays are from different Azure comms services with same host smtp.azurecomm.net:587 but with different username and passwords
Suppose i have 2 domains setup with 2 different sender dependent transport and each domains has 50 users setup.
What i want to setup is,
when all 100 users send 100 emails simultaneously,
the 50 emails that are to be routed to SDT ID1 should be sent sequentially and with a delay of 2 seconds between each email.
The same should occur for SDT ID2 but with a different delay say 3s.
Is this achiveable and how can the configure this when there are multiple SDT ?
