Question: iCloud filters the email I send for spam

Recently I have tried to forward a circulating email about how your mind autocorrects spelling mistakes.

However iCloud's outgoing spam filter did not think this mail was appropriate as it contained

U CAN R34D 7H15

Telling friends to forward a joke or entertaining content is not that evil.

Is this a new "feature". Is this common?

Do I need to cc myself to check if my mail gets sent?

Normally I don't forward this sort of content, but in this case my dad wanted to send it to me, and he wondered why I never replied. So I had to investigate.

All other mails I have tried get delivered fine.

Just this one, which is a bit spammy looking, will not get delivered. No error message about non-delivery is returned to me.

I have tried sending to myself directly. Originally the mail had a long text, and by sending about 30 emails, cutting away lines, I narrowed it down to exactly those few words which made the mail undesired.

I tried making a screen shot of the offending text. That made it arrive as expected, so I don't think iCloud OCR the text.

Below is the full text of the offending mail, which I believe is many years old, but still in circulation. Perhaps Apple decided it is about time to end the life of this one :-)

To my 'selected' strange-minded friends: If you can read the following paragraph, forward it on to your friends with 'yes' in the subject line. Only great minds can read this. This is weird, but interesting!

If you can raed this, you have a sgtrane mnid, too

Can you raed this? Olny 55 people out of 100 can.

I cdnuolt blveiee that I cluod aulaclty uesdnatnrd what I was rdanieg. The phaonmneal pweor of the hmuan mnid, aoccdrnig to rscheearch at Cmabrigde Uinervtisy, it dseno't mtaetr in what oerdr the ltteres in a word are, the olny iproamtnt tihng is that the frsit and last ltteer be in the rghit pclae.

The rset can be a taotl mses and you can still raed it whotuit a pboerlm. This is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the word as a wlohe. Azanmig huh? Yaeh and I awlyas tghuhot slpeling was ipmorantt!

If you can raed this forwrad it.
