Q: Yosemite OS 10.10 Mail Memory Leak

Yes. That is why I used the little devil emoticon. I tried Mail Drop once and it failed. I tried again and then it succeeded. But what I learned in the process makes me much more reluctant to ever try it again, at least with an iCloud e-mail account. Ironically, Mail Drop would probably work much better with GoDaddy.

I am having the exact same problem, with my imap godaddy email not updating. I was on the phone with apple for quite some time. It was a sync problem and he seemed to get it working by deleting all my trash. The trash sync was slow. But within an hour after we talked, it came back. Ugh...please let me know if you get this solved. I talked to godaddy also and they say it is a mail problem.

This is crazy, now my GoDaddy IMAP account has stopped syncing and displaying new messages too. I have to keep force Rebuild it every few minutes. What is going on now? Time to start a new Discussion I suppose? Or has someone already started one? Thanks!

I've had this same issue for quite some time.  My other accounts will get new messages, but my GoDaddy (work) IMAP account often times stalls.  I notice messages on my iPhone which leads me to Quit and Restart Mail.  That usually results in new messages coming in right away.

I'm guessing this is a different/unrelated bug, but that's just a guess.

I think it is a different issue because I had this problem before the memory leak problem and before I upgraded to Yosemite. I am a new user to this community and joined because of these two problems. If someone starts a new thread, please let me know.

I too had this problem before the memory leak and before I "upgraded" to Yosemite.

The same thing happens with Gmail. Sometimes it will run along and sync okay, and other times it just won't. I can see email sitting there on the Gmail server for hours and hours without it coming into Mail. This started with Mavericks.

Ironically, it never is a problem with iOS  mail. I wish the two teams would get together and talk.

Because of the syncing problem, I've stopped using mail for now. After all, the bottom line with an email client is actually getting the mail, right?

Also, since Yosemite, time machine does not work well with Mail. If I am enter time machine from within Mail, I just see a bunch of empty inboxes. And even if I don't request any restores or press any buttons, when I leave time machine  my accounts  information gets changed. For example, the order of the in boxes will change.

I spend hours talking with a "senior advisor" a couple of weeks ago and sending them a lot of data, but I never heard back after that.

What a mess. I'm using Mailplane for now.

I am having this same issue with the memory leak since Yosemite upgrade. I am willing to provide any information to help, just let me know what you need and how I get it. This has been going on for weeks now without resolve. I have had 2 trips to Genius bar and not resolve. Please help me. For now, I am just opening my email when I need to send a message and then periodically opening it quickly before the memory pressure starts to build. This is becoming very annoying and is killing my productivity as I work from home. It seems to reset every time I close mail. Anyway, I am willing to help just let me know how to send in logs.

The memory leak is related to mail attachments. Once you start opening messages with mail attachments and sending message with attachments, the memory buildings up based on the size of these attachments. I do not have the fix, but one should retest any potential solutions by opening and sending messages with attachments.

I can confirm this -- I had one email with a total of 22 mB of attachments.  I opened and closed that one email repeatedly.  Each time the memory usage of mail.app increased by about that much.  And never went down each time I closed the email.  So the total mem usage just kept going up till I quite mail.

I found a thread to disable Save Drafts on server for my Go Daddy IMAP account and it seems to have worked. I worked on this memory leak for 4 days and nothing worked. I have now beat this up for an hour or so and it seems to have fixed issue. Good luck.

Disable Save Drafts on Server on GoDaddy (maybe others) IMAP accounts - worked for me.

Hi gobigbue24, yes, that is a temporary fix. We discussed it several pages ago. It's obvious that you didn't read this Discussion because you could have had this temp fix days ago. We do appreciate you posting your findings very much so, thank you. We have not "marked" that as a solution because it's not really a solution, it's just a temp fix because, like me, it's vital that I be able to save my Drafts on the server and now I can't. Thanks!

I had the same problem, tried everything including clean install.  But today working with an AppleCare rep we found the problem, hope this works for others. In mail, go to Window on the menu bar and then drop down to a Activity and open that up. You will see a window that displays your mail activity. We discovered that there was constant synching activity with a message in my draft folder and the mail server from that account. It was causing the memory usage to go through the roof as it kept attempting to sync and the activity kept multiplying.  I deleted the draft and all is fixed. When you open mail you should see "activity" when your accounts, mailboxes and messages first sync with their designated servers. After that initial sync your activity window should display no activity unless of course you are composing, sending or receiving. If you see activity going on and you are not doing anything at the time, that's your culprit. So find the bad boy and  get rid of him.  At least it worked for me!

This seems to have worked for me, too. I have several email accounts that I use regularly, but the one that I seemed to have the most trouble with was one that's hosted at GoDaddy. It could just be that that is the account from which I most often compose longer messages containing attachments. But I haven't had the issue since disabling "save Drafts on server." There was also an OS X update in there somewhere, but I had already changed the drafts behavior.
