KMail periodically forgets about my SMTP passoword, even though I always have the "Remember password" checkbox checked in. I also have KWallet open and working (all apps work fine and remember my passwords). It's only the SMTP password that I have to type in again and again.

It doesn't happens each time I send mail, but one time each day. This behavior is perfectly consistent.

Reproducible: Always

Steps to Reproduce:
Try to send an email with KMail, check the "Remember password" checkbox.
Try to send an email again in one-two days.

Actual Results:  
The SMTP password is not remembered.

Expected Results:  
I would expect the password to be stored, since the appropriate checkbox is checked in.
