I am sure that user at domainb.com has installed his own private key through
mail preference.  I even try sending encrypted mail without saving sent
mail but the same error appear.

Also, while sending *signed* but not encrypted mail from server B to
user at domaina.com, mail can be correctly verified in server A.
