Was bedeutet das j in mails

In emails, the "J" in the sender's address or in the "From" field typically stands for "cc" or "carbon copy". This is an old-fashioned term that dates back to the days of paper-based correspondence.

In the past, when sending a letter to multiple recipients, a carbon copy (cc) was made by placing a sheet of carbon paper between the original letter and a second sheet of paper. This allowed the recipient to keep a copy of the letter, while the original was sent to the intended recipient.

In email, the "J" in the sender's address or in the "From" field is a relic of this practice. It's a way to indicate that the email is being sent to multiple recipients, and that a copy of the email is being sent to each of them.

For example, if an email is sent to multiple recipients, the "From" field might look like this:

From: John Smith [[email protected]] J

This indicates that the email is being sent to multiple recipients, and that a copy of the email is being sent to each of them.

It's worth noting that the "J" is not a standard part of the email protocol, and it's not required by any email client or server. It's simply a convention that has been adopted by some email clients and is used to indicate that the email is being sent to multiple recipients.
