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 mygroup@example.com, will emails sent to mygroup+subaddress@example.com or my.group@example.com go through to the group email address?

If I have an alias myalias@example.com, can I use myalias+subaddress@example.com or my.alias@example.com in the same fashion?


Plus signs: Yes.

  • Groups: I just tested sending an email to mygroup+something@example.com, and the message came through allright.

  • Aliases: Successfully tested sending an email to myalias+something@example.com.

Arbitrary periods: No.

  • Groups: Test message to my.group@example.com is returned with a Delivery to the following recipient failed permanently message

  • Aliases: Test message to my.alias@example.com does not seem to be delivered.

  • Just tried adding a member with a plus sign to a Google Group and it failed: "x+banana@aaaa.bbbb.com" at position 1 invalid: These characters are not allowed: + – joehanna Oct 26 '18 at 5:10
  • @joehanna Yes, but this is about valid group addresses, not addresses of group members. – Vidar S. Ramdal Oct 26 '18 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. – joehanna Oct 26 '18 at 7:03
  • @joehanna Good point, I have made an attempt at clarifying the title. – Vidar S. Ramdal Oct 26 '18 at 7:34
  • 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 myalias+tag@mydomain.com but i didn't receive anything at myalias@mydomain.com – iSWORD Nov 1 '18 at 15:30
