the above is my shaping.toml file, please have a look and suggest if I am doing something wrong,
this issue is occuring when the message size goes beyond 1 MB
When any message goes above 1mb, or when a message being relayed to SES goes beyond 1mb?
yes when, the emails are relayed to SES goes beyond 1MB, although in 1-2 retries it gets delivery so just here is my concern why the message are getting transient failure.
And when you send a message that large to somewhere other than SES?
As of now no, but we are going to implement to route the mails to other vendors as well.
So this is only a problem when talking to SES and nowhere else? That likely means the problem doesn’t reside in KumoMTA since then it would appear everywhere. I’ll look at testing.
Yes, I am hoping that’s the case
If needed I can share my full configuration as well.
With this being isolated to SES I think we can just test without using your config.
