Hello! I have installed qmail1.03 and vmailmgr to realize the function of virtualdomains,it's all ok. then I want to add up a webinterface "sqwebmail 2.0.0",but I don't use vpopmail,so I am considering how can I make it check passord throut a external program, such as the auth program of vmailmgr(checkvpw),I look up the configuration file "authmodulelist",it write the following: authcustom authshadow what is authcustom?how can I realize the auth function through vmailmgr? is there another better webmail program?
