Email. Problem during delivery processing Reason: Error in sieve filter: Notify mailto:recipient is not a valid address

I've been getting these as well. Initially they were to my aliases, but then for my primary @mac.com address as well. All were commercial sources. I tried sending myself an email from a GMail account I have with the same results, regardless if I use @mac or @icloud or @me. I then sent myself an email from my mac account and still recieved the message from "postmaster". Apple shows a green all systems ok for Mail. Glad it's not just me

Not sure. I would have thought that an Apple representative would be monitoring this site, pick up on this issue and post accordingly on the icloud status update site, since this is an Apple Supported venue.

I've had the problem all day, still happening here in the UK at 21.30 GMT 7-Mar-2013

as of 4:45pm EST it appears that this is still an issue. I've just gotten 5 of these messages in the past hour.

Problem During Mail Delivery

Reason: Error in sieve filter: Notify mailto: recipient is not a valid address

Delivery processing continued in spite of these errors.

It has been going on for the whole day now and no end in sight. It looks like the iCloud is again having serious trouble. They might want to attract some repair wizards who'll fix this in an hour.

Started yesterday morning the 6th PST. Seems every time I receive an email from anyone, there is this additional "problem during delivery processing". Internet mail delivery a message that comes along after the original email.

Never seen it before ...been with apple along time. Hopefully will be fixed soon...hopefully APPL stock will fix itself soon too!

I am still getting this error at 09:10 EST Sydney Australia. It is happening to all my addresses icloud, mac and me and all aliases.

I am still getting the exact same issue. Even when I send e-mail to myself! I have the problem but my father and wife who are on my me.com account don't seem to have the problem. It's not bugging me as much when I am on my desktop because I finally set up a rule to filter out the messages but it's a pain to read my e-mail on my iPhone and iPad. (As of 3:14 p.m. MST)

Same problem here. I called the number I found online for the so called "mytechsupport" for apple. After a series of questions, none of which relate to my issue, she tells me I have a "bug" on my phone and I need to pay 100.00 for a service plan.

obviously its not my phone alone here.

Me too. Been going on all day. (I'm in the UK.)

Same here... Was afraid I'd been hacked in some way - seems like more of a technical issue?

I should not have to pay for a new hardware support plan to fix their server issues!!!!

Yep, I'm getting it too; going to @aol.com emails. Surprising that some people still use aol. 😁

Seems to have been resolved at this point

Since the past hour? According to this thread- it seems to be going. I haven't been wasting my time resending emails all day until its cleared up.
