Mail refuses to send emails with large attachments

[XNoreX]

Steps to reproduce

You need to open the mail app, create a new email, and upload an attachment weighing ~100 MB. Send it and wait for the result:

Expected behavior

Expected behavior: sending an email with attachments, php, apache, and mail server limits - modoboa allows you to send emails with large attachments, and the issue is tracked by nextcloud mail

Actual behavior
