I just install the latest version vpopmail + courier-imap, I found there is good ability to check password guess through check the table vpopmail.vlog in mysql.
but is there a function of vpopmail to disable the connections of such cracker's IP for minutes to protect account security?? or other ways?? and is it possible to configure courier-imap with same ability?? I found courier-imap only refer the auth type and no IP record. Thanks! T.J.Ch
