iCloud.com & me.com addresses seem BLACKLISTED!

OMG - you ae sooo right, i had a brain spasm - THANK YOU. So does that mean my mssg too is gone? SHall I repost without the emails addresses - just the server names?

The Hosts will just edit your post to remove the addresses, though it might take a few hours. There's no need for you to do anything.

I've been trying to solve this problem as well, and one piece of information that I have not seen contributed is the impact of the version of Mac OS X running on the respective desktop.

I have two computers, in the same household, sharing the same external IP address (via AirPort Extreme BaseStation NAT). One computer can send out from an iCloud account using the iCloud SMTP server, and the other computer gets the dreaded "MTA poor reputation" bounce back (with no mail delivery to the intended destination).

Both machines are using the default Mail program that is part of Mac OS X.

What's the difference between the two? Here's the difference: The machine that is successful is running Mountain Lion (10.8.3). The machine that gets outgoing messages rejected is running Snow Leopard (10.6.8). I tested sending 5 emails from each. The 10.8.3 computer succeeds 5 out of 5 times. The 10.6.8 computer fails 5 out of 5 times (receives the bounced email message about "MTA poor reputation").

So I took a close look at the Mail configuration on each computer. In Snow Leopard, the Mail program has no "native knowledge" of iCloud, since it didn't exist when this version of Mail was released. So its configuration for the Outgoing Mail Server (SMTP) appears (and is editable) in the list of SMTP servers and uses the server hostname smtp.mail.me.com. On the computer that is running Mountain Lion, the Mail program HAS native knowledge of iCloud, and so if you go into the Mail settings and attempt to examine the SMTP settings for your iCloud mail account by using the "Outgoing Mail Server (SMTP)" pop-up menu, you can see the iCloud SMTP server in the pop-up menu, but if you select "Edit SMTP Server List", the iCloud SMTP server selection (which was in the pop-up menu) is NOT in the list of editable SMTP servers, and you cannot actually even see what the settings are! Ah ha, so Mountain Lion Mail apparently has "native, behind the scenes" knowledge of iCloud and so whatever voodoo is going on is working. But with the Snow Leopard computer, where the SMTP server is manually configured and manually editable, it is not.

So on the Snow Leopard computer, I edited the (editable) SMTP server for iCloud from smtp.mail.me.com to the one that John suggested above, p01.smtp.mail.me.com and IT WORKS! I can now send outgoing email from that computer.

So my point here is that all the talk about ISP's and IP addresses and trying to unblacklist oneself doesn't hold water because TWO different computers in the same residence, going through the same AirPort base station, both to what I thought was the same SMTP server, were behaving differently, and I was able to resolve the symptom by switching to the "apparently newer" SMTP server hostname from the "classic" (Snow Leopard) SMTP server hostname, which for whatever reason, seems to be the victim of blocking.

I hope this additional bit of information helps someone else. And thank you John and louiexiv for the key to unlocking the solution.

One extra bit of information: at some point, Apple must have extended usernames to support (and possibly in the future require) @me.com as part of the username. This wasn't the case long ago, and so my Snow Leopard machine actually still just had "username" and not "username@me.com" - I added @me.com to the end of my username in both the incoming and outgoing configuration fields for username for good measure. I don't think that was required, but it doesn't appear to have hurt, and perhaps in the future will be required.

thanks Roger

Thank you for that info - it seems then that my theory of my prob. being isolated to two local email addresses then is not the case, nor is the fact I thought it was related to Apple's modern technology not supporting old systems as was the case I encountered with purchasing songs from itunes, and publishing on iweb, etc.

Am curious if this is a temporary. I guess future replies will tell. Thanks again

an update on my story is that the two matching email addresses I was having this problem with are now seeming to go through fine without any problems, so I wonder if Apple read the problems everyone was having and has fixed the problem. Either way it seems to now be all in working order. I'll report back if I have further problems. Thanks to all who helped suggest ways around the bug.

All,

Now discovered my solution to use an alternate SMTP does not fully work

When i use

p01-smtp.mail.me.com

I do not get the email rejection problem, however is i send mail from my ipad or iphone it will no sync up with the mailboxes i have on my mac???

As soon as i reset my Mac Smtp back to the normal smtp.mail.me.com i can see all my sent messages again.

However has Apple fixed the issue that initially caused the mail rejection issues?

Thx

John

As far as I am concerned, the problem is solved. Has Apple tackled the issue?
