Can't send mail . . .

Thanks to you and all the other commenters for the helpful suggestions. I use Entourage 2011 (Mountain Lion 10.8.5) and started having this problem yesterday afternoon. I changed my outgoing mail server in Entourage [Entourage->Account Settings->double click account to open preferences window->under "Sending Mail" change SMTP server to p01-smtp.mail.me.com->click OK]. It worked. Now I can send emails from Entourage again.

Previously, my outgoing mail server was smtp.mail.me.com. I have a 2012 MacBook Air with exactly the same setup and strangely enough, it never stopped working. In fact, while I was having these problems on my Mac desktop, I was saving unsent emails to Drafts then pulling them up from the Drafts folder through Entourage on my Air and sending from there. But I agree with the other posters who say this is an Apple issue.

"p01-smtp.mail.me.com" worked.

Interestingly, I spoke with several Apple tech people today who (1) had no idea the problem was occurring and (2) had no idea how to fix it.

Didn't permit them to invoke the "talk to Microsoft" dodge.

I've had the same issue just with my @me.com email for the past 48 hours or so... a big thank you to DallasAppleMan...
p01-smtp.mail.me.com ... now emails back to normal!

Heh Dallas Apple Man - thanks very much. Curious how you figured out to change the outgoing server?

Thanks, and I'm glad the fix worked for you too, but I can't take credit for it. Credit goes to John and TheGuyInTheProjectionBooth and others I am sure.

Yes thanks for the acknowledgment as i indicated on my original post

this issue has happened to me at least 3 times over the last 2+ years and i am getting more than slightly p....d o...f at Apples total lack to professional response to this recurring issue.

However your support is greatly appreciatted

Thanks from Down Under ... p01-smtp.mail.me.com .. was an instant 100% fix .. Praise the Lord for the Apple Community. Especially when this is clearly an apple change not an entourage change!!!!

I was going to thank DallasAppleMan, but apparently the credit goes to several people - sooo thanks to all the smart folks. This issue began 2 days ago for me, but I didn't have time to look at it until today. I'm using Outlook for Mac [I know Steve is turning in his grave] and I was determined it was a Microsoft issue due to recent updates, but now I stand humbly corrected.😮

Thank you, thank you, thank you! For everyone who has either figured out or shared the solution to Apple's glitch, thank you from the bottom of my heart!

The change to "p01-smtp.mail.me.com" worked right away! I have a 2012 MacBook with Office for Mac 2011 on it. Started to have this issue early last week - could not send mail from the MacBook, but iPhone and iCloud were fine. Had a short period where sending was possible, but then it stopped again yesterday. Not 100% sure, but it was my impression that when I tried to send anything with attachments it seemed to make it worse/stop the whole show again.

Anyway, thanks again! Love the Apple community!

I'm a newbie...Using Outlook 2011 for Mac. Mine just stopped working...added 'p01-' fixed it right away.Thanks to whoever figured it out!!

i'm using a symbian belle phone(nokia n8) and my outgoing email also stopped sept 25th. the "p01" didn't work by itself. after reading many threads i checked my icloud settings in it's system preferences panel on my macbook pro, and i found icloud mail was unchecked(can't remember if i had done so before). after activating it in sys pref my phone email cliet started working again! i had added the "p01" earlier to no avail, not sure if it's needed, but don't want to mess with the settings now that it works.

Thunderbird is not compatible with iCloud. Won't work. That according to an Apple tech when I tried it some time ago.
