Why MailOnce May Block Remote Images in Suspicious Messages
Understand the privacy and safety reason for suppressing remote content when a message looks suspicious.
Quick answer
When a message looks suspicious, blocking remote images can prevent the inbox from contacting external image servers automatically while you are still deciding whether to trust the content.
Delay remote contact until context is clear
Suppressing remote content keeps the first read focused on text, sender and intent instead of silently loading third-party resources.
A temporary inbox changes how long you keep the address, not the basic rules for trusting a message. Sender, destination, timing and the action you actually initiated still matter.
Some email content contacts another server when it loads
Remote images are not just decoration. Loading one can make a request to an outside server and may reveal that the message was opened. Blocking that content by default in a suspicious message preserves more control until you decide the context is trustworthy enough.
The practical takeaway
Blocking suspicious remote images is a privacy boundary, not a claim that every image is malicious.
