Kolab2: postfix/lmtp 550-Mailbox unknown

[Harald Brass]

With kolab2 (of 1 Dec.) installed "out of the box", mail cannot deliver 
mail locally if  the respective user has been created with the username 
"username" (without "@domain"). The mail is rejected, the postfix log 
shows "postfix/lmtp 550-Mailbox unknown". The reason is that postfix 
tries to deliver to username at domain, while Cyrus only knows username.

It has been proposed to set all usernames as "username at domain". In this 
case the delivery works, but the internal cyrus data structure is more 
complicated.

It seems there is another solution which I found more convenient for my 
purposes and which might be interesting for others as well:

Set "virtdomains: off" instead of "virtdomains: ldap" in 
/kolab/etc/kolab/templates/imapd.conf.template and 
/kolab/etc/imapd/imapd.conf. After this change, Cyrus strips the @domain 
portion. Of course, this implies that all kolab users are part of one 
mail domain.

Kind regards

Harald

/>>/ 'lamer at time.net <https://kolab.org/mailman/listinfo/kolab-users>'. What is happening is that the mailbox is being created 
/>>/ as 'lamer'. Postfix passes the message along to lmtp for 
/>>/ 'lamer at time.net <https://kolab.org/mailman/listinfo/kolab-users>'. Cyrus looks for a mailbox for 'lamer at time.net <https://kolab.org/mailman/listinfo/kolab-users>' and 
/>>/ reports that it is not found. The old admin guide on the Kroupware site

/>>/ automatically. This doesn't seem to be the case.
