mis-parse of Received header token "([unix socket])"
Last modified: 2009-09-07 03:49:00 UTC
SpamAssassin can't parse the following header, because it wants an IP address inside the ([...]), and "unix socket" confuses it. The confusion causes the received trust chain to be broken. Received: from hathor.gsd.harvard.edu ([unix socket]) by hathor (Cyrus v2.3.7) with LMTPA; Fri, 15 May 2009 20:32:11 -0400 Yes, the literal words "unix socket" appear in the header where you would expect an IP address. Replacing that text with "127.0.0.1" would work.
