I would now be gratefull if someone can clarify the authentication method used by vpopmail as it's got me stumpped, and I need to now install "Courier Imap" and "Squirrelmail". I installed vpopmail with "roaming-users" and with "mysql" but not with replication, however on looking through the /home/vpopmail/domains directory I noticed that "sqwebmail-pass" was in the Maildir's. Does this mean that I am using "Sqwebmail's" password type authentication? If so, how will that effect me setting up and using "Squirrelmail" and "Courier-Imap" for webmail? Will it force me to use "Sqwebmail" instead? How can I change the authentication used by "vpopmail" to something more universal that would suit "Squirrelmail and Courier-Imap"? Lastly, has anyone setup a combination such as [Qmail - Vpopmail - Courier-Imap - Squirrelmail] and possibly Qmailadmin successfully, that could give me a few pointers please? Thanks in advance for any and all help, it's much appreciated Regards Roger
