HIGHESTMODSEQ not increasing

[Ronny Forberger]

It works now again. It was supposingly an error with the maildir. I 
created the maildir around year 2002 and copied it several times between 
mail servers and OSes. I created an new maildir and copied back all 
messages.

Best regards,

Ronny Forberger
