+PH/04 The IGNOREQUOTA extension to the LMTP protocol is now available in both
+      the lmtp transport and the smtp transport running in LMTP mode. In the
+      lmtp transport there is a new Boolean option called ignore_quota, and in
+      the smtp transport there is a new Boolean option called
+      lmtp_ignore_quota. If either of these options is set TRUE, the string
+      "IGNOREQUOTA" is added to RCPT commands when using the LMTP protocol,
+      provided that the server has advertised support for IGNOREQUOTA in its
+      response to the LHLO command.
