Mail addresses with a "+"?

Solved

Hello everyone,

I often hear about email addresses containing a “+” (for example: simplewith+symbol@example.com)

I looked it up on Wikipedia, but even though the English page ( https://en.wikipedia.org/wiki/Email_address ) is more verbose than the French one, I couldn't find the information...

Could someone please tell me how these addresses work? And what are their particularities?

Configuration:  a great mix of awesomeness.

    'Hi,

    If I'm not mistaken, what comes after the "+" is a folder in which the email will be stored.

    Example:
    my email address is toto@tata.fr
    I give the email address toto+friends@tata.fr
    This means that the email will be sent to toto@tata.fr filed in the inbox in the "friends" folder.
    In any case, there was a time when it worked like this for Gmail accounts, so I assume others have been inspired by it :-)

    Hi,

    An email address with a + isn't anything special ;-)

    It's just that it uses a symbol. Many characters or symbols are allowed in the standard. Thus, '@com is a valid email address.

    But in reality, many messaging services limit the usable characters.

    Best regards

      Hello,
      thank you for your response, but I was actually wondering if this plus didn't lead to a particular behavior (as suggested by kevin76110).

      I tried it on Gmail, toto+titi goes nicely into the inbox of toto, but not into the titi folder.

      On the other hand, the same thing on my professional email gives the response: no such user here, which seems to me to be the normal functioning.

      This therefore seems to be a specific feature to certain services, not a rule.

      In Gmail, it's an alias function: https://support.google.com/mail/answer/22370?hl=en&visit_id=637166648113619041-2040979455&rd=1

      With a filter, you can redirect messages arriving at toto+titi to a specific folder. The advantage is, for example, when signing up for a forum (CCM :-) and providing it with the account email toto+ccm. Then, in Gmail, you create a folder named ccm and a filter so that all messages from ccm will be grouped together.
