Replying to myself here to add a bit more information... I captured some tcpdumps of the emails moving around and realized that the problem happens prior to the message leaving the first server. You can see this in the pastebin above -- the first received line above the blank is from localhost by the first server. I used the sendmail binary to send the message manually with the same result. Using the '-n' sendmail flag to dump the message text looks normal. So the blank line is being added by the local Courier server at some point between being submitted by the sendmail binary and being sent out to the final destination. How can I determine what is happening in Courier to cause this? -- Bowie ------------------------------------------------------------------------------ Slashdot TV. Video for Nerds.
