Hi,

As Seun said, there is a default privacy setting in GNU Mailman software (that facilitates the mailing list) that flags Blind Carbon Copy (BCC) mails to mailing lists in the manner that you experienced.

For alternative behaviour, the administrator or moderator has to explicitly make a change:

To accept all BCCs to the list and get rid of this message entirely:

However, the main reason behind this setting appears to be for the protection of you and your mailing list colleagues from what was recognised at some point to be a spammer characteristics. The setting could be inconvenient though.

By way of example, as I was composing this, I received a spam message as a BCC'd message from a former client with what looks like a malicious attachment. That message probably went to all of the entries in his address book. If he was on the At-Large mailing list, then we would not have received it due to the very setting at issue. The spam engine is likely sending one message to a significant number of recipients in the BCC field. The more convincing spam tends have a person as a single recipient, or rather than a huge list of unknown recipients.

From a pedantic viewpoint, whilst you may need to BCC to a distribution list (an identifier that conveniently points to and expands into multiple email addresses), one would more conduct a broadcast or discussion with an electronic mailing list / listserv (an email client independent announce or discussion based, automated membership facility allowing all members to be reached via a single email address). One should not need to hide the action of messaging a mailing list as per its original purpose.

I do utilize groups (in Google) and mailing lists (in Mailman) sometimes for the convenience of being better than distribution lists especially with respect to being email client and device independent. Sometimes, I don't wish for one group to be aware that I emailed the other group the same thing, for whatever reason. However, with Mailman, unless I'm administrating it, I have to toe the line.

Moderation for technical reasons or in line with an acceptable use policy is quite different to any concern about it being an "open list".

Good discussion. Have a great day!

Regards,

Jason Hynds

Hi Seun and Carlton,

I think this has to do more with the List Serve Providers than with any other rules.  It seems the List serves also do not like HTML text and prefer text only at least that is what IT has told me was the answer to why my emails to the ALAC list serve were coming out blank

best,

Judith

SO: Don't know how many recipients exist in that particular mail you sent but it's just a technical precaution. I believe the settings can be further adjusted to not moderate up to certain level of blind copied recipient.
