Hi Paul, Thanks for your words.
On my specific case and after day to day investigation, what's killing my setup is the dbmail_headername+value tables, where I have in the headervalue table millions of lost records from weird headers. Due to the huge number of records the nightly dbmail-util can't handle this, not a dbmail-util issue, just a matter of the number of records. I've set the header_cache_readonly = yes, but I keep having new records in dbmail_headername. Any idea on this?
