20100515 Bugfix (introduced Postfix 2.6): the Postfix SMTP client XFORWARD implementation did not skip "unknown" SMTP client attributes, causing a syntax error when sending a PORT attribute. Reported by Victor Duchovni. File: smtp/smtp_proto.c. The latest 2.7.x release is 2.7.3, this fix is included in that release. -- Viktor.
