\033[1mDescription\033[m
|
|
|
|
Script determins the 'last login' time (pop/imap) for each mailbox of a domain.
|
|
If no domain was given at the command line, statistics is written for all mailboxes
|
|
of all available domains.
|
|
|
|
Note:
|
|
this script expects a file '.las-log' at homedir of each mailbox. the timestamp of this
|
|
file is used as 'lost-login' time of the concerning mailbox.
|
|
|
|
Configure a dovecot service to touch '~/.last-login' at each pop/imap login. See also:
