note Kozz <p>Well, I've tried enclosing the bcc recip list in single quotes, and also have tried just opening a pipe to sendmail as suggested, and also combining them, but they all result in an X-Final-To header.</p> <p>Conclusion: I blame it on the host for running <b>Sendmail 8.9.3</b> which is (as of this writing) over <b>5yrs old</b> (and getting that upgraded will be like pulling teeth). Argh. The host shall remain nameless. </p> <p>Thanks to you who've reviewed this question and offered suggestions.</p> 360464 360464
