hello colleagues I'm having a problem, a user receives an email with an attachment, and the email is deleted, the same email is sent to another user of the same domain with the same attachment and he does receive it. I checked and they both have the same spam filter. what could be happening? or how can I allow said attachments to be received within the same domain? My installation is on Debian
Check the mail.log of the server to see what happens with this email. And it might be that the email gets removed by spam filter software on the user's desktop or by its mail program, so this can be completely unrelated to your server.
