MailMate doesn't support more than 15 emails.

Some extra details.

The app is only running at around 150mb of RAM at the time of crash with ~62 threads.
I'm running Yosemite.
I'm using SSL enabled GoDaddy servers for most of my email. Google for the rest (just a few).

Could you try the latest beta (see the Software Update preferences
pane). I've made some change recently which should make it better at
handling a large number of accounts.

(Be patient since I'm on vacation this week, but I'm willing to look into whatever issue it is your having with a large number of accounts.)

This has seemed to drop down to 12 emails on my new computer. What could be the difference here? My new computer is better all around. I've updated from the beta build as of yesterday.

Could it be the amount of messages? I've sent/received a ton of messages since I last was able setup the 15 accounts.

On second thought, the new (13th) account I am trying to sync at the moment has no sent or received messages so that can't be it?

Which revision of MailMate are you running now (see the About window)?

In any case, you can a cutting edge test release here (r5136). Try that and let me know if it still fails.

I am running Version 1.9.2 (5107). Trying that now.

It worked! I was able to setup 16 accounts. What was the issue?

For some reason the older version is working as well now.

I see. Alright. Well seems to be okay now. I will continue using the "cutting edge test release" for now.

Thanks! You're awesome.
