Hi, I have the same problem here, and my situation is this one :
default domain crated at zimbra installation was : mail.domain.be
Spam/Ham addresses are connected to this one.
I then created the domain : domain.be
Then I saw that the spam/ham trainning wasn't working as it should so I tryed to rename the spam/ham address removing one of the dots but it doesn't seem to work, and when I run the command zmtrainsa I get this :
[] ERROR: can not find account
spam.f6csl.ezc_@mail.domain.be
[] INFO: Total messages processed: 2
Learned from 0 message(s) (0 message(s) examined).
Learned from 0 message(s) (2 message(s) examined).
bayes: synced databases from journal in 1 seconds: 1935 unique entries (2712 total entries)
How can I fix this please ?
