Because there was no answer, I had to write my own dirty hack
to put clint's IP number instead of 'imap' - I run attached
python script as next to authvchkpw authentication module,
using daemontools:
#!/bin/sh
exec /usr/sbin/softlimit \
-m 15000000 \
/usr/bin/tcpserver \
-p -X -c 30 -u 66 -g 66 \
81.10.225.17 imap \
/opt/sbin/imaplogin \
/opt/libexec/authlib/authvchkpw \
/var/lib/vpopmail/opt/imapd-auth-wrapper \
/opt/bin/imapd ./Maildir 2>&1
Of course you have to set your own mysql user, password and
database to reach lastauth table. I still do not understand
why courier-imap treats things different than pop3 server -
this design is not admin-friendly :-(
