BTW the errors that I had been getting were, at first: response exception: (450, b'The from.email must be verified. The from.email must be verified.') but later changed to: response exception: (450, b'Sorry, please try again. 429 Too many requests.')
I had assumed both errors were being generated by MailerSend but now I'm not sure
Yes, they are from your smtp_host which was mailersend
Both those are retryable and will be retried by Mailman to a point. I suggest if you want to use mailersend that in Postorius DMARC Mitigations you set DMARC mitigation action to Replace From: with list address and DMARC Mitigate unconditionally to yes.
That will ensure all posts are From: the list address and will probably avoid the 'The from.email must be verified. The from.email must be verified.' error.
