[vchkpw] What's the better Webmail for Vpopmail?

[Edilmar]

Hi,

I have used Netqmail 1.05 + SMTP Auth + Vpopmail 5.4.0 + SQWebmail 4.0.5.
But my users have talked about changing the webmail, mainly because
layout limitations
and other resources like virtual disk, support online for many
languages, instant messages
when new emails are received, etc.

I look at SQuirelmail but it needs IMAP and I'd not like to install a
new service.

I look also at Openwebmail but I didn't find a distribution integrated
with QMail/VPopmail.
Is there one?

Or are there other webmails more advanced than SQWebmail?

Thanks,
