Can google mail open p7m

A very specific question!

P7M (Pretty Good Privacy, Message) is a file format used to store encrypted email messages. Google Mail (Gmail) does support P7M files, but with some limitations.

Here's what you need to know:

  1. Gmail can decrypt P7M files: Gmail can decrypt P7M files that are sent to you as attachments. When you receive a P7M file as an attachment, Gmail will automatically decrypt it and display the contents of the email message.
  2. Gmail can't decrypt P7M files sent from other email providers: If you receive a P7M file from an email provider other than Gmail, Gmail may not be able to decrypt it. This is because the decryption key is typically stored on the sender's email server, and Gmail doesn't have access to that key.
  3. Gmail can't encrypt P7M files: Gmail can't encrypt email messages as P7M files. If you want to send an encrypted email, you'll need to use a third-party encryption tool or service.
  4. Gmail has limitations on P7M file size: Gmail has a file size limit of 25 MB for attachments, including P7M files. If you try to send a P7M file larger than 25 MB, Gmail will reject it.

In summary, Gmail can decrypt P7M files sent to you as attachments, but may not be able to decrypt P7M files sent from other email providers. Additionally, Gmail can't encrypt P7M files or send P7M files larger than 25 MB.
