Postfix, after expanding the alias, is not transmitting the original envelope recipient email address to dovecot and cannot record it in a Received: header. The LMTP DSN extension allows postfix to specify an ORCPT= parameter to the "RCPT TO:" line (in postfix src/smtp/smtp_proto.c). However, dovecot does not support the DNS extension on the LMTP endpoint. It has preliminary support of the ORCPT parameter in latest versions but is is disabled and not working. The solution taken was to add a sieve script to parse the Received: header written by postfix and parse the original RCPT TO address from it. Then add the header through the "editheader" sieve extension. Later sieve scripts can take this header to perform further filtering. |
