Hi.
If checkpassword interface is used for working with vpopmail, function
vpopmail "Record time and ip of last auth attempt"
(--enable-auth-logging option for configure) won't work - the file
"lastauth" is created in Maildir, but does not contain ip-address. If
I
had correctly understood, dovecot woldn't have set a enviroment variable
TCPREMOTEIP for vchkpw.
If changes are made in auth/passdb-checkpassword.c (a patch in
attachment), everything will work.
Probably, the patch is incorrect and does not solve all problems,
however the request is to pay attention to existence of the problem.
Also it is possible, that a similar problem exists with other variables
TCP UCSPI protocol (http://cr.yp.to/proto/ucspi-tcp.txt).
P.S. If use the interface vpopmail instead of checkpassword, the file
"lastauth" will not be created at all, that is a little bit
inconvenient.
