[PATCH 0/7] sendmail: improve recipient address handling

[Aaro Koskinen]

Hi,

Here's some suggestions for sendmail applet. While I understand it's
"bare bones" implementation, it should at least handle the most common
cases for recipient addresses, or if not possible, then fail in a safe
manner. This set tries to implement/fix the following (when -t is used):

 * If the address looks wrong, don't try to correct it, instead drop it
   and warn.

 * Support "Real Name <address at foo.bar>" type of addresses.

 * Support multiple comma-separated addresses.

 * Support long header fields when adding recipient addresses.

 * Don't add multiple To: fields.

I'll only accept review comments sent with busybox sendmail. :-)

Aaro Koskinen (7):
  sendmail: avoid sending mail to wrong addresses
  sendmail: don't mangle e-mail headers
  sendmail: support addresses inside angle brackets
  sendmail: support address lists
  sendmail: support long header fields for recipients
  sendmail: don't add To: header if it already exists
  sendmail: don't add multiple To: headers
