Our school newsletter often has a few images accompanying news articles. These images load fine on android phones and in regular computer browsers. Images do now show on the same message and email account when viewed on iPhone's. On iPhone all I see is an outline of an image with file name and none of the images load/show. Articles/text loads fine.

We are on v. Mailman 1:2.1.18-1, Debian 3.16.3-2

You mean "not show", I suppose?

This is likely an iPhone AppleMail issue. It is known that it does not handle MIME structure well. I'm not sure, the Gmail app may do better (for Gmail users only, of course). Are these messages HTML with cid hrefs, or are they MIME-structured with multipart/mixed? Are you reporting based on your own experience? Have you tried the Gmail app instead of AppleMail? (These questions are diagnostic, I'm not suggesting that you tell your users to switch.)
I think the issue is dmarc_moderation_action which we use to wrap the message or munge the headers. This works great for our Yahoo and AOL parents -- school newsletter is not spam filtered anymore.
These messages are all HTML MIME-structured with multipart/mixed. Its a global issue, not a single iPhone/email/user -- its everyone with an iPhone, they can't read our newsletter. Images do not load. I tried using Gmail app and it seems to work! iPhone Mail app does not load images in the same message/account/phone/network.

This issue is with the iPhone Mail app, and only Apple can fix it.
I can't say whether complaining to them will help, but sending them a copy of the raw email and explaining what's deficient with their rendering may help.
In the mean time note that the major reason I gave up on dmarc_moderation_action = Wrap Message on my lists and went to dmarc_moderation_action = Munge From is complaints from iPhone users. The iPhone Mail app, at least iOS 7, seems to do better with these, but my lists are plain text so my experience may not apply to you.

I tried disabling dmarc completely and apparently there is still an issue with HTML emails loading images on Apple iPhone Mail app.
Are these images attachments of the emails, or are they just linked into the html from elsewhere? If the latter, have you looked at the html to see if there are errors in it?

Peter, as mentioned earlier the HTML newsletter with images displays on everything but iPhone.

Yes, that's a well-known issue and as Mark says it's purely an Apple Mail app issue, and there's nothing we can do about it on Mailman side. As you noticed the setting of dmarc_moderation_action doesn't matter.
There is something you can that may appease Apple's Mail app, and that is to turn off *all* Mailman trimmings for *all* recipients. That means that you cannot have a footer or header (the text fields must be *empty*, if they contain even whitespace MIME structure will be added), and you cannot have a subject tag (like [Mailman-Users] in the version of this message you get via the list) or post serial number.
Unfortunately there's no way to do this *only* for Apple Mail app users (these are listwide settings, not per-user settings), and it's pretty draconian. I can't even promise it will work (that depends on the posting MUA as well as on Apple Mail app), but it's an option that you can decide whether you want to try.
Good luck!
