I've studied the other threads having to do with this error but have not been able to solve this. The error is:
mail imapd: Error reading ACLs for : Invalid argument
I get the error if I log in via webmail. Everything seems to be working properly except I get this error.
I have made sure permissions on the roundcube folder/sub-folders and files are www-data:www-data. I have done the same for the /var/vmail folder except there permissions are vmail:vmail.
I do have whitelist/blacklist entries (have not removed them).
my setup is a ubuntu 10.04 lts perfect server with ispconfig 3. Using courier and roundcube.
Please, if possible, give me some ideas of what is wrong.
Thank you, Eric
