Title: Amazon SES new signature version 4
Post by: ad on March 16, 2021, 06:59:42 am

Hi,
I was notifed by Amazon SES that I used an outdated signature version 3 instead of the now required version 4.
I have no idea what they are talking about as I do not know how to create a signature in email headers.
Since years I am using LM v1.89 without any issues.
I am connecting to tls://email-smtp.us-east-1.amazonaws.com port 465 with my Access Key and secret.
As far as my Amazon stats show LM still sends emails out but who knows when this stops.

Anyone here who could give me a hint on what I have to do?
Best regards
Wolfgang

Hi Wolfgang,

I think you may need to simply recreate the SMTP credentials in the AWS console. I found the suggestion here (https://stackoverflow.com/a/65911305/).

Note a comment on the linked answer says "Instead of creating the IAM user for sending raw SMTP emails on the IAM console you should instead create it on the SES console under SMTP Settings > Create My SMTP Credentials." which may be helpful.

Regards
