Since I updated to Yosemite Its been over a month and I still have the problem… cant believe apple could suck this bad. Ive been an apple user since back to …. I hear you; as soon as I bought my first Macbook, I was hooked! I purchased a Macbook Yosemite and guess what??? Same problem! Anyway, after fiddling for a thousand years, this is what worked for me on my new laptop Yosemite. These are rather detailed instructions for what worked for me. I now can finally send securely, authenticated and reliably, in Close Apple Mail.

Remove internet password entries that are SMTP connections to the server you cannot connect to. Close Keychain Access.

Open Keychain Access 5. Click on the certificate 7.

Close the certificate window Close the Keychain Access app. Key points: I too have spent an absolute eternity trying to fix this problem of getting and being able to read incoming mail, but not send since installing yosemite. Cursing my once loved Apple, swearing never to buy another. I discovered that — for whatever reason — they were not all the same. No joy. So I eliminated the Yahoo account on Mail — I had to go through internet accounts to do this.

I then set up Yahoo on Mail again — my name, email address and password. Hey presto! It works! I stopped using mail a year ago and went to Unibox after trying to fix problem. Both mails gmail and my company s mail working perfectly Many thanks!!!!!!! Very frustrating. I have the exact symptoms mentioned above in sending email with Yosemite OSX. Even with changing UserAllowsInsecureAuthentication in four places for three accounts in the specified file I still get send failures. I can send from my iPhone and Mac laptop just fine. Anyone else have an issue like this?

Neither fix worked for me. Laptop I use comcast.

The problem started right after I got the I already bumped into these solutions and tried them. We tried ports , , SSL on and off.. So no go on my end. I selected this box and the problem disappeared. I updated my iMac Outlook works fine with my att yahoo accounts but nags me to enter the pwd. I removed the gmail account from Outlook and started over creating a new account and it does the same thing. Outlook simply hangs and Mail client is unable to save setting changes in preferences. I only have 2 email accounts set in Mail, 1 Google and 1 Exchange. I found a solution, which in my case, helps greatly in Yosemite to keep Mac Mail online, and if it does go offline, makes it much easier to reconnect.

In Internet Accounts, click on each mail account. Try using Mail now for a week or so. I hope it works for others! Excellent tip, the second option with editing of the. Non of the 2 option s worked for me.

How to set up Comcast IMAP email on iOS 7, OS X Mavericks

The last time I had this issues I needed to remove all accounts and add them again but this is not working this time. Then eventually with the Manage settings box ticked only in Outgoing server but unticked in the mail account settings it worked!!! People the solution is to create an app specific password for Mail from your Apple ID page in Safari. It worked!

How to set up email in macOS Sierra Mail and Mojave

I did have to re-enter my full email address in step one because it only showed my user part. It worked fine for me this time. Many thanks. I have also tried all other fixes suggested online. I completely deleted the email account and set it up from scratch, which solved the problem for a couple of days. Sometimes closing mail down and reopening releases the problem, but not at the moment.

If I could return to Mavericks I would, but too much time has elapsed and backups from when I had mavericks are too old and incomplete. This is a problem because its the only browser that my work webmail works with. None of the suggested fixes helped with that one either. Mine was already in True and it has exactly the same problems… Apple are horrible to ignore this and not send any fixes. Shame on Apple.

Question since I am not programmer savvy, does this change in the plist put my mail at risk? The article specifies twice the following:.


  1. Configure Your Email Settings to Comcast Email.
  2. transport tycoon deluxe pour mac.
  3. Can't send email from Comcast account.
  4. mac os x open minimized window.
  5. Email Configuration Settings.
  6. hp laserjet m1522nf scan driver for mac;

It has exactly the problem described here since I upgraded from Mavericks; i. The only way I currently have to send email is to reboot from my Mavericks partition, in all of which the Mail Accounts information is identical to what is in El Capitan. Neither solution worked for me. Might as well switch back to Windows as Apple are really starting to suck in many areas — this just being one.

I tried everything.

2 Possible Fixes for Mail SMTP Sending Errors in OS X Yosemite

The problem was that when adding a new server in mac mail you can make a mistake very easily. Under description I had a random name to describe my location but it actually has to be the outgoing server name. So you basically have to enter the outgoing server name twice under description and server name. Hope this helps. Wonderful information. Thank you for sharing! I was having all the same problems nothing worked. But I found an offending app that was running. Turned it off and I could email again. Something was conflicting about that app. From the Mail app select the Window pulldown menu, then select Connection Doctor.

If the password entry is blank, enter your Gmail password and click OK. Obviously this is working for a lot of people but every time I try to follow your instructions, my Mac does not show the same options in the Mail menus — very frustrating. I started by being unable to send email from any of the 3 different gmail accounts I have for different traffic. If I saved them as drafts though, they appeared in Gmail on webmail and I was able to send from there. That no longer works. My advanced tab in Mail does not give me the options you show.

It is all a bit beyond me and it is not OK not being able to use email. Any other ideas. My Advanced tab, just shows a TLS certificate box while serve settings is greyed out and I cannot do anything with it. Please if someone have a solution for my problem please let me know asap.
