Yosemite OS 10.10 Mail Memory Leak

I agree, it seems to be Godaddy IMAP, when composing email. I disabled the save drafts option on server as you suggested - thanks. I'm going with that single change for now, leaving all other settings on all other accounts unchanged.

MY MAC IS NO LONGER RUNNING OUT OF APPLICATION MEMORY AND THIS IS HOW

Thank you to everyone who has been contributing to this thread.

I too have had my system "run out of application memory" many times per day since upgrading to Yosemite.

With the help of this thread I traced it to the Mail app, and to my GoDaddy IMAP mail accounts in particular.

I'm posting just to make the solution very clear since I struggled to find the exact steps:

1. Start the Mail app

2. On the Mail menu open Preferences...

3. Click on "Accounts"

4. Click on "Mailbox Behaviors"

5. For each IMAP account, uncheck “Store draft messages on the server”

That was the only change I made, and now my system is no longer running out of application memory.

Has anyone submitted a note and/or copied a link to this thread to GoDaddy? Seems like they should know. If not, I will. RWH

please do. you have my proxy.

Update: since changing the Draft settings with my GoDaddy IMAP account, no memory creep issues.

However, I continue to have issues with Receiving GoDaddy IMAP mail from time to time. It comes through the iPhone 6 fine. However, the new messages will NOT show up in Mac Mail unless I Quite and Restart Mail. Then they appear. This is yet another BUG IMHO. I have no problem with my Gmail messages being received in real-time. It's just the GoDaddy IMAP account - which is where I run my business.

Is anyone else experiencing this type of issue with GoDaddy IMAP accounts?

Yep, same for me... Changing draft settings has fixed the memory leak... and get the same problem you mentioned with emails not syncing properly between my work iMac, and Macbook Pro... Sometimes a bunch of emails will show on my iMac and I haven't noticed since I've been on the Macbook all day... Frustrating.... but another topic and another thread I guess...

I think this is all under the same topic. It's an IMAP issue with Mac Mail. I've had this problem since upgrading last week but today (and since I made the changes with Drafts), it's not syncing GoDaddy account at all this morning. Seems like a band-aid one on part of the issue creates another bigger issue - not receiving mail at all.

Thank you to all of you who are informing Apple and GoDaddy about these issues. Looking at this from a pure business perspective, Mac Mail is not the right solution for my business at this point. Hope we can all find a fix soon b/c my patience is running thin.

Yes I have had the same problem with my GoDaddy IMAP accounts for the past few months, even on Mavericks. I get emails on my iPhone and then they don't show on on my iMac. My workaround is to click on the lightening bolt ("Take All Accounts Offline"), then after they are offline, click the envelope ("Get new messages in all accounts") and then it will retrieve the missing emails.

I'm glad that several are finding solace in the Draft theory that I had tested. Cool.

As far as not receiving emails to my IMAP GoDaddy account, I've also been having this issue, but it had taken a back seat to the memory leak issue, which, may or may not be related.

Taking the Accounts offline & getting new messages has never worked for me unfortunately, but it's also a great idea & hopefully works for most. Thanks simplegenius.

I'm fortunate because I'm able to tell when I receive an IMAP GoDaddy email because my iPhone receives it, which is sitting right next to me, but when the Mail.app does not, I do this:

1. Highlight my Inbox (So I can do them all at once)

2. Pull-down menu: Mailboxes

3. Select "Rebuild"

After this I again see "all" of my incoming messages. Sometimes I'm doing this several times a day. Again, not a "true" solution", but hopefully it also works for you as a temporary fix.

That entire issue should probably be a separate Discussion actually too.

Thanks to Doren_Sean_Michael who I believe figured out the uncheck drafts on server option. It has been working for me.

As for the IMAP GoDaddy problems with unreceived email, GoDaddy has been aware of it for at least a year. They have not done squat about it, and it is THEIR problem, not Apple's. I say this because IMAP accounts with other hosts do not have this problem on Macs, just GoDaddy accounts. And this was way before Yosemite. I don't have the link anymore but there is a thread on GoDaddy's forums about this problem that goes back at least a year.

If anyone figures out a permanent solution to the unreceived emails problem, please let us know! Having to constantly check on my phone, or by closing and reopening Mail is getting tremendously annoying...

I'm keeping Activity Monitor open on a second screen so I can keep an eye on it. Every time Mail starts chewing RAM, it's doing the following, trying to index some ungodly number of cache items:

I haven't teased out any cause and effect relationships (when I do X, Mail starts updating the cache...), but the actual behavior is 100% consistent.

Hopefully, this helps Apple figure out what's going on so it can be fixed.

For what it's worth, I had the problem too - just once so far, knock wood. But I am not using GoDaddy email at all. So I don't think it is them per se. I think it's just a memory leak in the new Mail.app and Apple has to fix it.

Apple, I just bought a new Macbook Pro with Retina and it has 8 gigs. I am 100% unsatisfied and if the developers do not come with a solution, I will return this ****. And this is my first mac, what a shame!

My method for dealing with the Mail memory leak bug is just to check the Actiivity Monitor every once in a while and when Mail starts using more than 500 MB of RAM to quit and restart it. When I do that it starts up at about 60 MB, quickly goes up to 100 MB and then slowly continues to creep up over the day.

So far it seems that doing this just once a day is enough to keep it from going out of control.

So I'll continue to watch and restart once a day until Apple fixes the bug.

Yes, have had the exact problem with my GoDaddy IMAP account both before and after upgrading to Yosemite. I've used the "sync mailbox" or quit and restarted Mail to resolve the problem.
