Subject: tin 3.9.3 [Not allowed to change header "From"]

From: [email-masked] (Therefore)
Date: 25 Apr 1996 10:15:55 GMT

In 3.9.2 I had this:

customized-hdrs          = From: Mark Kemper <[email-masked]>

which worked perfectly. In 3.9.3 I now get this error message:

   [Not allowed to change header "From"]

My intent is not to fake an address -- I own the domain therefore.com and
my ISP routes all therefore.com mail to my account. My ISP account is
[email-masked]. But I want my 'From' to indicate [email-masked]'.
Do I have any choice besides either reverting back to 3.9.2 or using an 
alternative tool?

Thanks!
