Bounce error when using Amazon SES Custom MAIL FROM domain

    Hello! I was hoping to get some help with an issue I’m having when using the Amazon SES Custom MAIL FROM domain setting through FluentSMTP.

    I have three email addresses linked through the plugin with their own user credentials in IAM. The identities have also been verified in Amazon SES in order to use the MAIL FROM feature in the SES settings. When the MAIL FROM feature is enabled, most emails send through the FluentSMTP plugin with the updated MAIL FROM id and are delivered successfully.

    The problem I’m running into is when trying to send emails through the FluentSMTP plugin to their own inbox (sending to self). When the MAIL FROM option is enabled, emails begin to bounce when sending to self. This becomes problematic when trying to receive core WordPress emails which are sent a send to self scenario in the case of the admin email.

    In the bounce notifications for these emails, it seems like FluentSMTP is using the message ID as the email account name when the MAIL FROM feature is enable causing the message to fail since this message ID/MAIL FROM header aren’t an actual account. Here are some of the errors shown (actual ids changed):

    When the MAIL FROM setting in Amazon SES is disabled, the self sending emails begin to work again. I have also tested email sending outside of FluentSMTP with the MAIL FROM setting in Amazon SES enable and send to self emails still work so it seems to be specific to the FluentSMTP plugin.

    I have tested with and without the FluentSMTP “Force From Email” setting enabled and this did not have an effect.

    Do you know what may be causing this to happen? It is important that I have the MAIL FROM option enabled as it is necessary to pass SPF checks for my emails.

    Thank you!
