Problem with uebimiau + dovecot

[tr4d3r]

Hello all, we are working just fine with ISPCONFIG, but, one domain can't get in webmail using uebimiau, in user we write gonzalo@xxxx.com and say to me that wrong password, if i go from outlook, web29_gonzalo and use the pass, it work, but in uebimiau not, all others domains work fine ... i see the configuration and notice that MailUser login was not checked when creating the site, so i put, and restart, i delete the users, create again, etc, but nothing ... in the last month i have some similar problem, i delete the site and recreate and everything work just fine, but this site i cant do this because there is many many data, DB, Pages, Configurations, etc ...


Anybody can help?
