Understand the UID value in mailbox debug
Hi list
we have a client who complains that mails from a certain sender are always put into his spamfolder. Our strong guess is that this is an issue with the webmail (Roundcube), but I need some help in understanding the output from dovecot's mailbox-debug.
In order to narrow down the source of the problem we activated the mailbox-debug from Dovecot. Now we can see that the mail is moved into the spamfolder. But the strange thing is that a UID is logged which does not exist on the mailserver
The following log is the "move" of the mail into the spamfolder
Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW copy from INBOX: box=INBOX.Spam, uid=58, msgid=000601d181cd$71401940$53c04bc0$@bluewin.ch, size=314585 Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW delete: box=INBOX, uid=1614, msgid=000601d181cd$71401940$53c04bc0$@bluewin.ch, size=314585 Mar 19 11:53:57 backend3 dovecot: imapREMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW expunge: box=INBOX, uid=1614, msgid=000601d181cd$71401940$53c04bc0$@bluewin.ch, size=314585
I do not understand whose UID this is, as it does not exist on the server. Does dovecot create temporary UID or something like that? Or is it more a process ID?
Thanks and regards
tobi

do you mean '58' ?
grep 58 /etc/passwd ?

it's the UID of the message. http://tools.ietf.org/html/rfc3501#section-2.3.1.1

thanks a lot this explains why I was unable to find the UID in passwd May I add another question related to mailbox debug log?
would it be possible to log the session ID (from IMAP login) that triggered the copy of the mail? I checked mail-log-plugin.c but could not find a session field. Basically I need to relate the action logged by mailbox debug to the respective IMAP login on the server.
If it's not possible at the moment to get this information, would it be possible to implement in future versions of dovecot?
Thanks
