Hello Marcos
sorry, but i'm back.
Didn't you experience a problems with an empty emails? I'll explain: an user move or delete an email from a folder via IMAP in Thunderbird, but after message is moved an empty(no body nor header) mails appeared, only in a local interface, not on a server.
I've got some cases when we first experienced this issue with IMAP scanning, but i didn't relayed it to EAV, but after i've re-enabled IMAP scanning with a new Internet module protection, i was noticed by some users of this issue.
I've tried to disable again IMAP scanning and no more problems, so i think it have a same source.
Is a log enabling can give more information about this issue?
