Comment 6 for bug 286290

Mike,

(1) The "new line in parameters" thing means that somehow debconf thinks there is a newline in a previous stored response to one of its questions, and that this is a problem. Are you sure you *purged* any previous postfix install before trying to install it afresh?

I just tried this here on Ubuntu 9.04 Jaunty amd64 and

  sudo apt-get purge postfix
  sudo apt-get install postfix
  sudo dpkg-reconfigure postfix

all work fine for me.

(2) I'm wondering what locale your machine and shell are using? Does doing

  sudo LANG=C dpkg-reconfigure postfix

make any difference?

(3) Your proposed domain name 2oceanview.com is not in the preferred form per RFC 1035, which has a syntax definition that shows that domain names should start with a letter.

Can you please try:

  sudo apt-get purge postfix
  sudo apt-get install postfix

and this time, use the domain name oceanview.com (no leading "2", just as a test!), to see whether that works for you?

Jonathan
