Managing domains automatically

Hi all,

We will be accepting email for around 80k domains. We are putting together custom scripts to manage the relay domains and transports via the API so that only new/changed/deleted domains generate a call to the API which works fine for us. The issue that we have is that the initial input of all domains takes 2-3 hours when done via our scripts that interact with the PMG API.

I notice that relay domains are shown in /etc/pmg/domains and transports in /etc/pmg/transport. Is there any issue with manipulating these files directly instead of using the API as this will be much quicker for our scripts to do? I realise that "pmgconfig sync -restart" will need running each time.

Thanks.

Currently /etc/pmg/transport and /etc/pmg/domains are the authoritative source of the information in the API - so it should work fine to just edit those files.
This might change in the future (for all readers who read this later) - so check the changelogs/release notes for versions after 9.0

You'd need to run `postmap` on both files after changing them - otherwise postfix will not see the new information.

I hope this helps!

Does "postmap" need running in addition?

from a quick look in the code and a quick check on a testsystem - no
(the part rewriting the postfix config templates calls postmap for all needed files)
 
The way we've done it for multiple cPanel servers, large number of domains etc, is to just make 2 API calls for relay domains and transports and then work out what changes need to be made, MX records to update and so on. Making use of the comments field helps with that too, and just means you can fire the same script on any server for any event. Initial adding takes a while for a new server obv but it's a one time thing so...
