Impossible to delete POP accounts from iCloud keychain and SMTP not working

Question

Hello,
After an aborted Mavericks clean install, I reverted to Mountain Lion via Time Machine and started experimenting with iCloud Keychain on Mavericks using trashable Virtual Machines.
I am hitting two serious problems with email accounts :
1. I turned on iCloud keychain ONLY on my Mavericks test installs (not on my iOS device)
2. First time I turned it on and used my usual AppleID, the test install retrieved all my email accounts (I have many of all types)
3. I could not make password SMTPS work on any IMAP accounts, so I decided to delete ALL email accounts from my iCloud Keychain
4. When you ask to delete an email account, it asks if you want to delete it from ALL your accounts, whoch is what I did (make a clean slate)
5. Of all the accounts I have, I have two old disabled POP3 accounts. I deleted them as every other one (including FB, Twitter, LinkedIN, Exchange, ...)
Every time I set up a new test install with iCloud keychain enabled, these two POP accounts continue to show up on the list.
Every time I delete them again from ALL keychains they disappear, but anytime I launch Mail they come back, and if I delete them again, and then I add a new email account they come back.
No way to delete them from ALL keychains
And BTW user/password SMTP on SSL for IMAP accounts does not work for me. It fails all the times on my postfix server.
So, my issues are :
- iCloud keychains seems unstable with email accounts (probably with POP accounts only)
- SMTP over SSL with user/password doesn't seem to work
Anybody hit the issue ? For me is a severe showstopper for Mavericks and iCloud keychains
Best

Restore it as new.  Why wouldn't you do that when purchasing a used device from another individual?
