A member of one on my groups is having a problem:
Some members (but not others) who post to the group have their sender addresses change from abc@... to abc@....? This causes them to go to his spam folder. ? It's impractical for folks to have to whitelist every member, and in fact, they might not know that that they're not seeing all the posts to a group (which is what happened with the member).?
I presume that this a holdover from some earlier situation and that groups.io is doing this mangling.? When I post, it doesn't change my address.
I have a some questions:
- What was the original reason this was done?
- What determines which members get this "treatment"?
- Does this still need to be happening?

Some domains will bounce group messages if this is not done.

Unfortunately, yes...if you want messages to be delivered. See ?

For future reference, it's usually called munging.? Makes it easier to find information about it, especially on this site.

Yes, munging is a term that goes back to my days developing Mac software -- originally applied to strings of text in the early '80s.? (There was a system call in the original Mac OS called "Munger" that manipulated one or two text strings in various ways.)
I know the manuals have lots of good stuff in them, but my increasing vision problems necessitate that I limit digging through manual pages.? I did do a quick search in both manuals for "mung" and nothing turns up.? Is this covered?? Does anyone here know anything about what I described?

Yes, but not using the term mung.? Searching for information about DMARC (in messages) should find a lot of it.

It is discussed in the FAQ, but is in neither of the manuals.

Much simplified, some email providers look up the IP address of the domain found in the From: line. If this isn't the same as the IP address of the sending server, the message may not be delivered. To get around this, the From: address is munged ("via groups.io") so the DNS lookup will match.

So how do people deal with the spam quarantine for posts from members?

I don't recall any member messages being called spam or quarantined, only non-member.

As I mentioned when I started this thread, my friend gets the posts with the munged sender addresses (that get converted to groups.io) trapped in quarantine.? I wouldn't advise him to whitelist groups.io as a whole.

You seem to be assuming that a munged address is the cause. Virtually every message I get from Groups.io has a munged address and none of them end up in my spam/junk folder. Providing the messages in you friend's quarantine are moved to their inbox, the spam filters should learn over time (assuming they're half decent).

Since you used the word "quarantine" in that reply, it sounds like he may be using a 3rd party anti-spam software, and it's set up too restrictive? Could he possibly have accidentally created a rule/filter that causes this? Anyway, many email clients have filters, so he can setup a filter that if the From: field contains "via groups.io" don't send it to spam, so unless he is at the complete mercy of an ISP's anti-spam service which he cannot control whatsoever, he should be able to setup the same filter/rule either in his email client or anti-spam app. He can also try setting additional filters that depend on the list name and whitelist the whole group.

Quarantine?in his context refers to DMARC processing, and is not related to any actions taken by the recipient. Pretty much every ISP implements DMARC, which requires a reverse IP lookup of the sender¡¯s email address to match the IP address in the originating message header. The actions taken by the ISP are Report, Quarantine, or Block.? Larry Finch
