O SX Yosemite 10.10 Smtp Mail Problem

I have the same problem using a brand new Mac Mini equipped with Yosemite 10.10. The Mail application refuse to connect to my TX service provider Videotron the largest in Quebec. Videotron is blaming APPLE for this serious problem saying MAIL was operating properly using 10.09 Maverick. After hours of testing at my Apple store, they still blaming each other about this serious malfunction. Finally since no body is taking the blame, i had to return this new computer after seven days of discussion with both companies involved with this unconnect situation. I am using Mail on my old G5 power pc without any problem. The same server is also used with MAIL in my IPAD and my portable 13in Apple without difficulties. The purchase of this new Mini Mac was for my 10 years old Power Pc replacement. If they fix that problem rapidly, I will have to switch to PC in order to get security protection for my data which is no longer available with G5 Motorola processer since all recent units run on Intel. But it is the way it is at this time, people concerned are not taking each other at this present time and who knows if they ever will. Regards

Just like to add my voice to this. Mail was working fine with Yosemite until a couple of days ago and all of a sudden the occasional "couldn't send email" warning has become much more frequent. it's also claiming to not sending a mail that was definitely sent as the person responded to it.

Was tempted to delete accounts and reset up but thanks to legion 3000 I know that's a temporary solution.

I also have webpages not loading or actions that are hanging in Safari. i'm not so down on Apple though. It's my fault to install a new OS without waiting for at least the first update.

On the other hand, if it wasn't for people like us they wouldn't know what to update. Curious though that these problems weren't apparent in the beta testing.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Mail/Provide Mail Feedback

Don't they monitor these forums?

I can not fix this e-mail problem. Tried everything the past two days. I hope the Yosemite update fixes this bug. I'm quite desperate by now!

Markl116 fix worked for me. This fix works on POP services. This is obviously a Mail issue within Yosemite. Hope it gets addressed in next update for those with problems that are different from mine.

While allowing insecure connection might solve the problem, this workaround is hardly acceptable, if at all.

Dude,

Today you win the "Needle in a Haystack" award.

Your VERY BRIEF comment helped me get beyond 3 weeks of tech support from Verizon, Yahoo and Apple.

Thanks

Hi,

I delete my email accounts, but I cannot re-setup them, any ideas?

Has the mail issues been resolved? I am afraid to upgrade to Yosemite until this is resolved. Everything on Mavericks works great for me. I don't want to mess it up.

I found a workaround (Mail>Preferences>Advanced -check the box "allow insecure authentication" which worked for me. HOWEVER, since the Yosemite update 10.10.1, I have NOT had a problem with Mail at all. I believe when you do the update the "allow insecure authentication" box is "un checked" by the update.

Despite this problem I have found Yosemite to be the best OS for my MacBook to date, but I like the continuity of style with my iPhone & iPad.

I'm having similar problems. I have 3 email accounts and all are failing to connect SMTP and sometimes IMAP. I tried a couple other mail programs Postbox and Airmail and they all connect automatically and work perfectly. However some of the junk mail setting are not as good as Mac Mail. I tried the same settings that Postbox and Airmail used (Both were the same) on Mac Mail ... IT DID NOT WORK. What is wrong with Apple to make connection so painful when a couple of competitors can blow them out of the water. I like Mac Mail and would like to get it back, but it has to work and be stable first.. Hello Apple are you listening ? FIX and simplify Mac Mail

Thanks for posting that. i am still waiting. I have not upgraded and I am not going to because of all this. I Have a roadrunner email account and although I have tried to get away from it, I have it. Time Warner is my cable carrier and I know there have been issues with TW and the new upgrade. I agree, Apple should have had all this worked out long before they released the upgrade.

After trying for nearly 2 months and reading all the articles yours was the only simple solution that worked. Thanks heaps
