Configuring Attachment Limits

Can I establish a restriction on attachment size? Additionally, I would like to automatically reject emails that do not meet the attachment size limit criteria.

Why limit attachment size? If the remote server has a limit they will send a bounce.

start_esmtp_listener - KumoMTA Docs can be used to limit the overall message size

Hi @yearning-hyena @free-spirited-yorksh I need to restrict attachment . My use case to block attachments used emails while senting emails

So now instead of limiting size you want to block them completely?

yes. i need to block attachment used emails.

Is it acceptable to restrict max_message_size to a reasonable text size? like 10k?

What is your desired result if a user does indeed inject a message with an attachment? Do you want the attachment stripped out, or should the message be rejected? or … ?

@kindhearted-deer did you resolve this question?
