iCloud.com & me.com addresses seem BLACKLISTED!

I too keep getting this Rejection/reputation response on different emails. I am in Italy and the emails usually work but then all of a sudden they don't. I'm not up on what all this means and waht i need to do though from what you and others wrote, it seems to be APPLES fault. IF so will it work again in time? If so i'll send from Gmail as you suggested.

This is w hat I"m getting :

Reason: Rejection greeting returned by server.

Diagnostic code: smtp;554-mtalibero01.libero.it Your IP 17.172.81.0 is rejected due to poor reputation. For further information contact your provider.

I am sending from Mac.com on a 10.4.11 OS and our provider is Alice.it

I am wondering if it's not a problem relating to how LIBERO and MAC or apple communicate, maybe Apple has updated some software that now no longer allows such communications to work?

I am seeing the same problem with my mac.com e-mail address - given that it is occurring with all three domains, it is probably an IP range blacklist and not directly related to SPF or other domain data.

Update: http://www.rackaid.com/resources/cannot-send-email-blacklisted/ has a good description of the problem - and it seems like the Cisco IronPort SenderBase Security Network (http://www.senderbase.org/senderbase_queries/rep_lookup?search_name=17.172.81.1& action%3ASearch=Search) is indeed responsible for our problems - although there is little that we can do about it except wait for Apple to clean up the problem with the iCloud SMTP delivery systems.

Same problem here, been getting the same two error messages, only occasionally.

I am experiencing the same email rejections. Thank you for posting your findings. Is there any way to know whether Apple is working to resolve the issue? And possibly an expected time for completion?

Same issues here for the last two days, even when I am sending emails to myself -- so even Apple has blacklisted itself?! How do we get this addressed as this is my business email!

The problem seems to have stopped for me (although perhaps I just haven't sent any e-mails to domains using the SenderBase reputations in the past few days) but I had a few work-arounds while I was affected:

1. (least desirable, but easiest): send e-mail from my GMail account, with Reply-To: header set to my mac.com address
2. (more desirable, slightly trickier): add SMTP server for my ISP (Verizon) and select it as the default SMTP server for my iCloud account - for some ISPs this may only work from home, but Verizon uses an SSL connection on port 465 with username/password login, so I can use this anywhere. See links below for instructions.
3. (may not work for everyone): as the blacklisted SMTP server(s) are not used for all iCloud accounts, some people reported that re-sending the e-mail from an iPhone worked fine - presumably these use different infrastructure from the MacOS systems

Excellent YouTube video showing how to add SMTP servers and set them as the default for a MacOS mail account: http://www.youtube.com/watch?v=5sqBTVVHjfg&noredirect=1 - be sure to Like this if you find it helpful.

I just unchecked the box that says "use only this server." I would hope that Mail.app would keep trying any and all other servers until the message finally goes out to everyone, but I'm not sure that's how it works.

Unfortunately, not quite. When Mail.app contacts a server, and the server accepts the e-mail message, it is done with it, and if the server that accepted the message then is unable to deliver the e-mail to its final recipient for any reason (like poor reputation) it is too late for Mail.app to do anything like trying to re-send via another server

The only time that unchecking "use only this server" will help is if the iCloud SMTP servers are unreachable due to network connectivity problems or iCloud server downtime (this has been a problem in the past as well). If Mail.app cannot contact the iCloud server then it will notify you and ask if you would like to try another server - but this happens shortly after hitting the Send button.

If you are still seeing bounces, I would suggest keeping your ISP as the default server for another few days.

Also, unless the To and CC recipients are in the same domain, it is not unexpected that "poor reputation" bounces could affect only one or the other. The iCloud servers will contact the SMTP servers for the domain of each recipient (e.g. icloud.com, gmail.com, msn.com) separately, and depending on whether they use the SenderBase reputation, only some of them may reject the message.

@alex

I've been getting a lot of bounce backs myself the past few weeks.

I've looked in the email headers, and the IP addresses are

17.172.81.0

17.172.81.1

17.172.81.2

They seem to be blacklisted by Lashback and Sorbs-spam.

ugh

Anyone tried using the alternative SMTP

p01-smtp.mail.me.com

Seemed to fix the issue for me...(Ithink!)

Hello,

Would it be possible to list some of the other alternatives please?

John

It's a really bad idea to post your email address - it's an invitation to spam - and I've asked the Hosts to remove it.
