I haven’t been able to send to one of my groups since Wednesday, possibly Tuesday. My messages are returned because the list doesn’t accept attachments. But there are no attachments on message.

I had originally replied to a messages so I opened a new messages and retyped it fresh. Same result.

I tried writing in TextEdit and had the same problem when I pasted it into a message.

Using MacBook Pro, OS 11.1, Apple Mail. The problem may have started when I installed the 11.1 update.

Anyone else having this problem or heard of it?

Sharon -- Your mail client is sending a digital signature (smime.p7s). This presents as an attachment.

Turn that off and your posts should go through.

Thank you,

How would I turn it off and why isn’t it happening with all my groups?

Mod's note - same attachment to this email. I deleted it. Likely it is a file associated with encryption for a signature.

This might be down to a small difference in Settings > Message Formatting .

Oops; something sent a reply before it was finished. (Sorry)

Attachments can be (a) Allowed (b) Bounced (c) Stripped (d) Moderated. Your current problem suggests that your "problem group" is set to Bounce.

I don't use Apple Mail, but I found this on the web:???

You answered that yourself...

Many groups -- like GMF -- allow attachments.

I changed it from bounced to stripped and that worked. I have POP accounts, no Mime. I can’t find any settings that would produce attachments out of thin air.

Thank you for the article — I see the icons for encrypted but had no idea what they are. I’ve been using mail for 20+ years but they do keep adding things.

Sharon,

accounts, no Mime.

Using a POP email client has nothing to do with whether your messages might use MIME to encode multiple parts and/or attachments.

air.

Bruce's observation is correct: the digital signature added to your message by Apple Mail is carried as an attachment.

Thank you for the article — I see the icons for encrypted but had no
idea what they are.

Your message wasn't encrypted (thank goodness), but the digital signature uses similar technology.

Thunderbird marks your messages with a button I'd not seen (or at least not noticed) before, labeled S/MIME (secure-MIME). It has a warning badge on it and clicking it tells me that your signature is self-issued and that I don't trust it.

Gmail's web interface, on the other hand, does not mark your message as having an attachment, or anything else of interest. Nor does its Android mobile app.

I’ve been using mail for 20+ years but they do keep adding things.

Yup.

There's been a long path from the relative simplicity of RFC 882 (the first post-ARPA internet email standard, in 1982) to today's RFC 5322 and the update to it (and all the "companion" standards defining things like MIME).

There was a push many years ago to make signatures and optional encryption a standard part of emails, but it never gained traction. It is interesting (to me) that Apple is now pursuing it so strongly as to (apparently) add it to a user's experience without notice or explanation.

(pardon me for geeking out about your "shiny" new signature).
