...a "compromise" wrapper solution (attached). It does not require patching dovecot (external module) and it's thus (supposedly) durable across dovecot releases; however, it cannot help with the colon problem. The wrapper works as follows: 1) compile and install: # cc -O2 -Wall -o checkvpw-dovecot-wrapper checkvpw-dovecot-wrapper.c # install -s -o root checkvpw-dovecot-wrapper /usr/local/bin 2) edit dovecot.conf, setup the auth section as follows: ============ auth default { mechanism = plain passdb checkpassword { args = /usr/local/bin/checkvpw-dovecot-wrapper } userdb prefetc...

...erface [ http://cr.yp.to/checkpwd/interface.html ] leaves room to interpretation when the scope is not system login. Vmailmgr and vpopmail, for example, collapse many mail users on the same system account. So, what "home" is here is not specified. In the case of vmailmgr, it's "checkvpw" sets HOME to the system user's home, and returns the path of the actual mail user differently. The solution I applied for this problem is to generalize the process that fetches authentication data (what currently is "checkpassword- reply"). I was set up for a specific passdb-v...

hello now that dovecot supports authentication with checkpassword-compatible modules, I tried to get it working for IMAP on a qmail + vmailmgr server. For a subtle detail, while claiming to be "a drop-in replacement for the standard checkpassword", checkvpw (auth module for vmailmgr) is not "drop in". It actually expects 2 args on its command line, not 1. So, a wrapper is needed to get it authenticating correctly with dovecot; a very simple one (argswrapper.c below). This wrapper is not sufficient though. In fact, vmailmgr represents...
