Hello,

Every time mail starts new it ask me to trust my mobile.me ssl certificate, what i do of course, but at the next start it appears again, same for ssl websites in safari every time a ssl popup to accept...

What i have done til now:

Repair permissions

drag the ssl certificate icon in the popup to the desktop and accept it manually

keychain utility edit all these ssl certificate and accept manually

mail:reenter account passwords accept ssl certificate again

reset keychain

this behavior appears at all account on the imac

ssl certificate are marked in the keychain utility as trusted

now I'm at the end of my knowledge....
