With `CHUNKING`set as a capability, nginx advertises this capability to clients at a stage where the SMTP dialog does not seem to be forwarded to the proxy-target (postfix) yet. Nginx' SMTP parser itself does not support the `BDAT` command issued as part of a chunke-d dialog. This makes Nginx respond with a `250 2.0.0 OK` and close the connection, after the mail-data got sent by the client — without forwarding this to the proxy-target. With this, users mail can be lost. Furthermore, when a user uses a sieve filter to forward mail, dovecot sometimes chunks the forwarded mail when sending it through `front`. These forwards then fail. Removing `CHUNKING` from the capabilities fixes this behavior. |
