Have you try 'sh /script/fixmail-all'?
Yes, I did. But still have same thing happening...
Only issue when I run it was:
Preparing Horde database
- Fix MySQL commands in import files of Horde
cp: cannot stat `/home/kloxo/httpd/webmail/horde/scripts/sql/horde_groupware.mysql.sql': No such file or directory
cp: cannot stat `/home/kloxo/httpd/webmail/horde/config/horde_conf.php': No such file or directory
but I am not using horde anyway.
Again, when sending email, everything works fine, mail is delivered from my host and I can see it in Sent in roundcube.
Is there any way to "test" maildrop, looks like that might be a problem...
Thanks
