What is "Create a receive-only email" option?


Samuel Murray
 

Hello

I could not find the answer to this question in the help files. What does the "Create a receive-only email address that posts to your group" option do? It makes no sense... how can a "receive-only email address do any posting? Or, perhaps I don't understand what a "receive-only email address is.

Thanks
Samuel

Using this option will create an email address for the group that can only receive messages, not send.  Anything sent to this email address will get posted to the group.  It can be set to deliver messages without moderation, even if the group is moderated, but can also be set to require moderation.  It includes the entire email address of the sender, including any name they may have set on their email program.  It's a convoluted string of characters that wouldn't be easy to replicate, so should be relatively safe unless you post it someplace.  If that were to happen, you could always delete it and create another.  One thing I noticed this morning is that there doesn't seem to be an entry in the Activity Log when these are received.

I'm still not quite sure what it is. Do you mean that non-members can post messages to my group if they send their e-mail to the "receive-only" e-mail address? So its like a one-direction subscription -- you can send messages to the gruop, but you won't receive any replies unless group members deliberately include use your From address?

What sort of situations would one use this for?

Yes, that seems to be how it works.  I've just done a test from an email address I have that is not linked with Groups.io in anyway and the message came through to my group.

The reply options can be controlled in the Admin > Settings > Message Policies section and can be Group, Group and Sender, Sender or Moderators.

Our group uses the email integration to automatically post web formmail and PayPal notifications to a "member management" subgroup. So it's useful for getting these kinds of automated notices into your groups.io message archive and distributed appropriately. They arrive with an #email hashtag that can be customized for topic duration, message delivery, etc.

You could also subscribe this email address to a listserv, or set up your email client to auto-forward messages conforming to certain rules to this address, or...

I cannot understand the benefit and do not recommend sharing an email integration address with non-subscribers.

Bruce

Samual,


Do you mean that non-members can post messages to my group if they send their e-mail to the
"receive-only" e-mail address? 

One specific non-subscriber address per integration. On first use the integration remembers the sending address and thereafter accepts messages only from that address. It does not create an open portal that could be used by anyone knowing the integration address.

Correct, mostly

Unlike an ordinary subscription, the sender uses this integration address to post to the group, not the group's normal posting address. And unlike an ordinary subscription, the group admin who sets it up doesn't need to know the actual sending address in advance.

What sort of situations would one use this for?

As Bruce said, the primary application is for posting notices from automated services, the key factor being that the sender doesn't have to be subscribed to the group (which can be tricky to achieve when dealing with a send-only address).

It could in principle be used for announcements from an individual (human) sender, but that case would more normally be handled by subscribing the person to the group, perhaps set No Email.

Shal, it would seem that a more accurate & descriptive name is needed to self-describe how this works.
It actually creates a direct, private, one way channel into a group from the email address of the first email received through it to the group, according to your description above.

I think I got it: it is "receive-only" from the group's perspective. It is "send-only" from the human's perspective. I tend to think human. :-)

Bob,

Duane has done some testing today that belies my description. I thought I had tested this behavior but instead they do seem to accept messages from all senders. I'm not sure if there is more to the story or if I have been simply wrong about that.

Shal, Ouch! 
Another open barn door?
Good reason for moderating postings to it.

So let's say there is a Yahoogroup called "chad" and we want all posts sent to chad@... to also be posted to chad@groups.io .  Could you use this email-only option to do this? If so, what would have to be done in both groups to make this work?  Assume that the person setting this up is the owner for both groups?

If an email-only email address does not work for this purpose, is there any other way to do it?

Regards,
Mike


 

Mike,

So let's say there is a Yahoogroup called "chad" and we want all posts
sent to chad@... <mailto:chad@...> to also be
posted to chad@groups.io . Could you use this email-only option to do
this?
In principle, yes. That would be the right way to do this, if you could subscribe the integration address to chad@....

In practice I was unable to get the Yahoo Group to accept the integration address as valid, either via the Invite function or the -subscribe email command. Alas, as that would have allowed the messages from the Yahoo group to enter the Groups.io group unmoderated.

If an email-only email address does not work for this purpose, is
there any other way to do it?
You can, from the Y!Group, invite chad@groups.io (check the Add only to mailing list box).

For this to work you'll need to have the "Allow Non Subscribers to Post" box checked in chad@groups.io so that the invitation, and subsequent postings by Y!Group members, will be received in pending. The invitation you should click its link while still in Pending, then delete it from pending (no reason to let that post in chad@groups.io).

That's the first bit of ugliness: no way to unmoderate non-subscribers. So every message posted to chad@... will need to be approved to appear in chad@groups.io. Probably not what you wanted.

The next bit of ugliness has to do with how Yahoo Groups modify the From address of posting members. It arrives like:

Display Name user@... [Y!tag] <Y!name-noreply@...>

Which doesn't seem so bad at first until you realize that it is exposing the posting member's email address, unmasked, on the web pages of the Groups.io group -- which is a really bad idea if chad@groups.io has public messages. Depending on the group, maybe even if chad@groups.io's messages are members-only.

And, of course, each such post includes the Yahoo Group footer, with the posting member's email address again (but this time it is at least optionally masked). But those footers will get tiresome in the Message Section and in digests. In individual messages chad@groups.io's members get both footers (oh, joy!).
