Detailed IMAP session trace, enable Dovecot rawlog


(Davide Principi) #1

For developers (@webtop_team), but also to troubleshoot some IMAP clients it is useful to record the list of IMAP commands sent by the client and server. The procedure to enable the “Dovecot rawlog” is available here

https://github.com/NethServer/nethserver-mail/blob/master/README.rst#enable-dovecot-imap-rawlog

This is an example of output from it:

[root@vm5 ~]# sort -n /var/lib/nethserver/vmail/first.user@dpnet.nethesis.it/dovecot.rawlog/20180913-143301-6293.*
