I installed ISPconfig 3 with Courier IMAP/POP3 and maildrop a while ago. Everything was fine, until i noticed that mail filters (like filtering junk or autoresponder) is not working because relay was 'virtual' not 'maildrop'.
I changed it to 'maildrop', filtering is working, but aliases or forwarding are not working anymore.
Now maildrop / postfix is not checking virtual aliases in mysql, it says something with permission denied, user does not exists, which is kinda true, cause there's no file/folder in /var/vmail for that user, it's an alias in mysql forward table.
So, my dilemma is how can i get both of them working, aliases and maildrop filtering?
right now i have this config:
virtual_transport = maildrop
best_mx_transport = virtual
changes were made to best_mx_transport from virtual to maildrop
if i comment out the best_mx_tranport or delete it, i get an error, mail looks back to myself.
domain to which i'm trying to send email and get the error does exists in domain table, it's working if i set it to virtual or maildrop.
hope that makes sens
