Any idea what this is?

Jun 26 23:16:34 quota-status(user@example.com)<4975><CLsXEzfSE11vEwAArt9ycg>: Error: quota-status: Client sent invalid recipient address: Invalid character in path

I have this enabled in my config

service quota-status { client_limit = 1 executable = quota-status -p postfix unix_listener /var/spool/postfix/private/dovquota { mode = 0666 user = postfix } }

this is given by the address validation routines (for example see lib-smtp/smtp-address.c as a starting point).

Maybe it would be easier to approach it by looking at the email address that gave the error.

Is the email address compliant to smtp standards? Does it contain utf8 characters? Does the email address correspond to a mailbox of the same name with a quota to be checked?

It is not just one email, the logs were full of them but I think I found the source of the problem. When I build from sources, libicu for FTS unicode normalization was checked. I have rebuild yesterday without ICU and no errors like those so far.
