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)

Sorry but this didn't help. I couldn't find a folder called containers. There is a logs folder but I couldn't find anything big in there. I recently upgraded from 4 Gb RAM because nearly all of the 4 Gb were being taken up by Mail and now nearly all of my 16 Gb is being taken up with mail!

The fix you suggested seems to work temporarily by deleting ~/Library/Containers/com.apple.mail/Data/Library/Logs/Mail/

Once the log files are deleted my system functions as normal for some period of hours of days. The log file then builds up again creating the same issue over and over. It does not seem to create a permanent fix of the issue. My last deleted logs where a total of 76 GB.

This is still an issue for me, I tried to remove the files under ~/Library/Containers/com.apple.mail/Data/Library/Logs/Mail/ but they come right back each time Mail is re-launched. and I only have a dozen of them, totall around 2MB tops, so I do not think it's the same issue... but it is the same symptom, memry usage goes up in 30 mins to 1 hour, and my Mail is always showing downloading XXXXX of XXXXX messages.

I also re-added all my accounts but no avail. any ideas?
