[I am suspecting a file locking issue between TB3 and dovecot, but this is not much more but a wild guess without having any evidence for it.] What I am actually doing is to filter incoming mails from several remote imap and pop accounts into a local dovecot-imap applying thunderbird filtering. </blockquote></div> Have you disabled "Keep messages for this account on this computer" for every account? This option is in the "Synchronization & Storage" tab for the account. The default is "on", unfortunately. -- Paulo Roma Cavalcanti LCG - UFRJ
