Mail on El Capitan

I am experiencing serious trouble wieh the Mail App on El Capitan

on an iMac with 32GB memory.

It grabs way too much memory.

When I had my my accounts activated, it would take all the memory and after

some time the machine would hang.

So I deactivated all my mail accounts and uset Activity Monitor

to monitor memory usage.

Here is a list of what happens (time in seconds)

Before starting mail

time kernel_task Mail

0 1.9GB x

After starting Mail

20 1.9 7.6

80 1.9 7.6

150 21.7 26.9

270 17.7 38.4

520 21.8 57.8

Now closing Mail

555 21.8 x

680 21.8 x

920 17.9 x

960 1.9 x

So Mail really uses all the memory it can get (icluding virtual)

and after closing Mail cleaning up still takes a frew minutes.

I also hav a MacBook Air with 8GB.

Mail works fine on this machine.

Mac Pro, Mac OS X (10.7.4)

Seems to have done the trick for me so far.

This seem to solved the problem. When I checked the size of ~/Library/Containers/com.apple.mail/Data/Library/Logs/Mail it was 23Gb!

Deleting all the log files and now everything seems fine. So it seems the Mail app was trying to compress 23Gb worth of files all at the same time? Stupid...

Thanks Miguel!

Solved the problem for me as well, I had over 60GB of logs.

Deleting the log files worked for me!

The file 2015-10-02_IMAPSyncActivity.log was 65 GB!!

Mine was even > 80GB. Deleting it solved the problem.

It sounds crazy to have over 80G log files...

I guess not so fast. Came in this morning and saw my Macbook dead. Turn it on and checked the log size and it's 32Gb. Turns out it consumed all disk space killing my Macbook. Had to reboot a couple of times to get it back to working condition. Now I'm keeping eyes on the size of the log files and it already grew to 300Mb in 15 minutes. Something weird is going on here. Any way to turn off the mail logs?

Have a look at the logs themselves, see if they're complaining about something.

My Mail.app was taking silly amounts of CPU and spewing these:

---

Oct 8 08:12:18 Mail[32344] <Debug>: Received an error while syncing: <EWSSyncFolderItemsResponseMessageType 0x7f9c43d84a00> {

MessageText = The folder to be synchronized could not be found.;

ResponseCode = 291;

DescriptiveLinkKey = 0;

MessageXml = nil;

SyncState = ;

IncludesLastItemInRange = 1;

Changes = nil;

}

---

Something was odd in my ~/Library/Mail dir, I moved it out of the way and everything settled down. (had to re-import all my local mailboxes)

So, see if one of your logs are much larger than the rest (mine was 2015-10-08_EWSMailboxSync.log)

In my case it seemed that the mail was logging everything on my exchange account. I had to delete that exchange account and added back and the log file does not grow any more... so far.

Deleting the log files did the trick, back to normal!!!!!!

Thanks. Are there other .log files or things to do like this to boost performance to my mbp? Doing your suggestion made not only my mail app work but my whole mac seems faster all around. Just curious if there are other tips like it to make it even more efficient and quick.
