Some PNG and JPEG attachments corrupted
Reported by James Cooksey | March 3rd, 2022 @ 01:44 PM
Some PNG and JPEG files are corrupt when saved and quicklook fails, just showing file info. The files are fine on iPhone/iPad email clients.
Examples of corrupt images:
JPEG:
This is a big one so haven't included the source, but looks to be
an issue with the MIME type. The file won't quicklook but will open
in Photoshop. Opens on an iOS device in Mail app. Message is from a
CCTV camera so looks to be at fault using wrong type, but could
MailMate look for the suffix here?

PNG:
Opens fine in iOS Mail app but completely corrupt when saved from
MailMate. No Mac app will open and Media Inspector unable to find
any valid media.

If you are not using the latest test release of MailMate: Hold down the option key when clicking “Check Now” in the Software Update preferences pane.
If it still doesn't work then, if possible, share the messages with me using “Help > Send Feedback” in MailMate. I can then see if I can reproduce (and possibly fix) the issues.
Before attaching the emails you should drag them out of MailMate and compress them using the Finder. This ensures that I'll also see any encoding issues which might otherwise be fixed by attaching.
(Even with the wrong MIME type
application/octet-stream, the saved file should work.) -

Hi Benny,
This was on 5852. I've updated to 5875 (which looks very smart by the way) and still there.
I've sent two offending emails. The PNG one renders correctly in Quicklook when viewing the EML file.
Cheers,
James

- State changed from “new” to “fixcommitted”
It took some time, but I expect this to be fixed in r5889+. Sorry about the delay.

Looks like it's fixed in 5889! Thank you Benny. Please, no need to be sorry!
Cheers,
James
