Well, the first part of the problem seems to be that Dspam may be sending incorrectly formatted UTF-8, because when I turned off smtputf8_enable in Postfix, the 'bad UTF-8 syntax' error went away. However, it seems to have been replaced by this: Oct 4 14:01:00 epsilon3 postfix/smtpd[11430]: connect from localhost[127.0.0.1] Oct 4 14:01:00 epsilon3 postfix/smtpd[11430]: 66BC5157019: client=localhost[127.0.0.1] Oct 4 14:01:00 epsilon3 postfix/cleanup[11433]: 66BC5157019: message-id=<20151004180100.66bc5157...@epsilon3.caerllewys.net> Oct 4 14:01:00 epsilon3 opendkim[3414]: 66BC5157019: s=mail d=houzz.com SSL Oct 4 14:01:00 epsilon3 opendkim[3414]: 66BC5157019: bad signature data Oct 4 14:01:00 epsilon3 postfix/qmgr[11405]: 66BC5157019: from=<>, size=132690, nrcpt=1 (queue active) Oct 4 14:01:00 epsilon3 postfix/smtpd[11430]: disconnect from localhost[127.0.0.1] helo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Oct 4 14:01:00 epsilon3 postfix/local[11434]: 66BC5157019: to=<????@caerllewys.net>, orig_to=<????>, relay=local, delay=0.56, delays=0.46/0.01/0/0.09, dsn=5.1.1, status=bounced (unknown user: "????")
