Thanks for the reply. Of course, sorry for the naïve query. Yes we use qmailadmin to allow password changes by end users. And we’ve just found a writeup here: http://mugurel.sumanariu.ro/qmail/qmailadmin-check-if-password-is-strong-enough/ but it seems a little dodgy. There isn’t by any chance a build time variable for qmail admin or something a little more within the source tree than the above patch method? Thanks again for your reply.

Are you wondering about the vpasswd program for changing a password? That's an admin program, and wouldn't typically enforce a password change policy. How do your users currently change their passwords? QmailAdmin? Some other program? You would have to incorporate password requirements into that program, and not the one that validates a password. -Tom On Oct 29, 2014, at 7:42 AM, Peter Brezny wrote: > Dear email@example.com, > > Is there a way to enforce a minimum length and character combination > (letters, numbers, upper case) with vchkpw and if not, are there patches or > external applications that integrate well with vchkpw to get this > functionality? !DSPAM:54512e1726514774016155!
