451 4.5.3 Too many rejections; try again later.

Count me in for the same problem. Only from gmail users, either rejected by server, or the message shows up as much as two days late!

Not to go all old school but is there an actual human being with a (gasp) phone number that I can call? I mean, this is happening to a ton of people yet there's no mention of it practically anywhere on the internet. It's a huge concern when you can't get business done and could lose your job. I tried to go through proper Apple channels but it won't give me a number without asking for a serial number which makes absolutely no sense to me at all.

I have opened a case with Apple support (and talked to an actual person!) as I have Applecare. We'll see what they come up with.

Thank you so much!!!! Fingers are crossed...

I am having the same issue for the past few days. Any solutions?

Relieved to know it's not just me, you should pardon the pun, but wish this would get sorted. Causing a royal pain, not being able to send email to clients.

I talked to applecare too. they think it might be a problem when gmail users send from the browser instead of an apple native app. he's getting into it with engineering. i'll let you all know if i hear anything!

...applecare is wrong...also happens with automatic forward from gmail with no browser at all involved.

Same issue, my girlfriends gmails are bouncing back to her from my @me.com account with this error message. Most of the gmail messages do eventually make it through but can take 2 to 24 hours to arrive. Emails I send her are not always delived or take 2 to 24 hours as well. This started on Saturday the 14th of March. Doesn't Apple monitor this forum? Why havn't they acknowledged this is a problem they are working on?

You cannot rely on the developers to monitor these forums .Better use the feedback forms to report bugs, feature requests, and other kind of feedback.

Same here, and I can actually say and prove that I lost an oDesk job because of this... I'm pretty happy now...

I'm running into the exact same issue - all emails from Gmail autoforwarded to @me.com address. Stopped receiving emails yesterday. Tried to disable and re-enable autoforward. Didn't help.

Called AppleCare this morning - tech spoke to supervisor..both came to the conclusion it was a Gmail problem...

I'm having the same problem - my gmail address has gone from delays to now totally unable to send to @mac, @me, or @icloud accounts. This weekend I went through a maze of questions to finally send a message to google so they could address - the confirmation screen said there was no guarantee I would receive a response. Still haven't heard from them and there's no answer at the headquarters phone number. Nice to know (in a weird way) others are dealing with this... having trouble doing my job/have had to create a new email address to send replies.

Exact same problem here. Gmail can no longer forward to my me.com address. Has nothing to do with any website since it has autoforwarded for years now. The problem started around Saturday, Mar 14.

Apple, please fix this serious problem!
