[imp] IMP and Courier - Login problem

[jlewis@lewis.org]

What version of vpopmail are you running?  Last I looked, the latest 
release version has a string handling bug that corrupts login data.

The easiest fix is to patch courier/authlib/preauthvchkpw.c. In the
function auth_vchkpw_pre, add the following directly under the static char
User and Domain declarations

/* hack to workaround authdaemond/vpopmail user corruption bug */
        memset(User, 0, sizeof(User));
        memset(Domain, 0, sizeof(Domain));
/* end of hack */

This issue was fixed with a complete rewrite of the function at fault in 
vpopmail, but you'll have to download a development version to get it.  I 
don't think they've released a fixed stable version.
