Mark posted this on Beta just a few minutes ago:
Hi All,
Earlier this morning, someone sent a massive 55mb 43k x 21k image through the system (the group was not set to resize images in emails), and it caused a bit of havoc with some processes running out of memory or taking too long to complete. I've changed it so that, if a group is set to not resize images, we will resize any images to a max of 10k per side.
Please let me know if you have any questions.
?
I am not sure whether it will stop several attachments that are too large. You might want to ask Mark through Beta.
And of course, there is the discussion on Beta that you posted.
