Email size

Hello everyone,

I would like to understand how FortiMail calculates email sizes, particularly when encryption is involved or more. The issue I’m facing is that the size varies inconsistently. I understand that factors like attachments influence the final size, but at times and very often, this instability causes emails to exceed the configured size limit, impacting their transmission. I want to avoid having to adjust the email size limit manually each time. Are there any solutions I might have overlooked? ?

Best regards
