Best Multi SMTP Sending Option?

[cueup]

Firstly, thank you to everyone working on and maintaining Listmonk - great tool.

My Setup

I'm using Listmonk to manage multiple SMTP sending accounts.

I want to leave all the SMTP accounts enabled choose which account is used based on the campaign I'm sending.

What would be the best way to do this?

1. Set custom header then set the from address in the campaign (does this then use the SMTP account based on the sending address?) [ { "From": "Name mail@example.com", "Reply-To": "mail@example.com" } ]

2. Set the header on the campaign itself?

I would also need to be able to set up different smtp for different campaigns. This is because I have to send campaigns for 3 different companies and I would like the campaigns to use separate SES, so that any problems on one do not create problems for the other campaigns.

Is it possible? or are some modifications necessary to achieve this result?
