Hi, in an installation of Dovecot I need to know when each user made his/her last POP3 connection in a maildir environment.

The date of which of the index files maintained by Dovecot can I use to get this information?

Well, as long as you don't have the filesystem mounted with "noatime" you can use the index file's atime. mtime might work well enough also, but it's not updated if there have been no changes to the mailbox since last login.

You could also change mail_executable to some wrapper script which updates some file's timestamp before executing the pop3 binary.
