Hellothe workaround listed at http://www.postfix.org/workarounds.html does include the following:
Disable SMTP command pipelining for all mail. This sledgehammer solution will reduce performance for all outbound mail, by causing extra network round-trip times.
/etc/postfix/main.cf: smtp_discard_ehlo_keywords = silent-discard pipeliningIt should also be possible to only do "-o smtp_discard_ehlo_keywords=pipelining" in master.cf for the entry used for SAV, no?
BTW: The problem also apply for mail to microsoft.com, not only for frontbridge customer.
Regards Andreas
