Do Google Apps group email addresses and email aliases support plus signs and arbitrary periods in addresses, like normal Gmail addresses do?

For example, if I have a group email address (e.g. one that I'm using as an alias) called [email protected], will emails sent to [email protected] or [email protected] go through to the group email address?

If I have an alias [email protected], can I use [email protected] or [email protected] in the same fashion?

Plus signs: Yes.

Arbitrary periods: No.

  • Groups: Test message to [email protected] is returned with a Delivery to the following recipient failed permanently message

  • Aliases: Test message to [email protected] does not seem to be delivered.

  • Just tried adding a member with a plus sign to a Google Group and it failed: "[email protected]" at position 1 invalid: These characters are not allowed: +

  • @joehanna Yes, but this is about valid group addresses, not addresses of group members. Commented Oct 26, 2018 at 5:28

    My bad. I figured he was referring to member email addresses when he mentioned "email addresses" twice in the title and description.

    for plus signs in aliases, is this the default behavior or is it something that must be enabled first? it doesn't seem to be working in my organization. i tried to send an email to [email protected] but i didn't receive anything at [email protected]
