Attempted to send email via telnet as a test

telnet localhost:8025
Type: EHLO <mail server internet name>
Type: mail from: <your_name@yourdomain.com> and press Enter.
Type: rcpt to: <recipient@recipientdomain.com> and press Enter.
Type: data and press Enter.
Type: Subject: <a subject here> and press Enter.
Type: This is a test message sent from telnet. and press Enter.
Type: . and press Enter

Server responded as expected up until attempting to confirm the contents of the email. It seemed to take <cr/lf>.<cr/lf> as part of the email body and never continued.

Telnet on linux by default may send <lf> instead of <cr><lf>. Please see answer: https://stackoverflow.com/a/22974813/434255

Also do this steps:

  1. download latest tag 0.0.4 via docker pull ontrif/slacker (it has fix for None fields)
  2. rerun container
  3. run ncat -x /tmp/out.hex --crlf localhost 8025
  4. enter all your commands and data
  5. check that <cr><lf>.<cr><lf> present in /tmp/out.hex
  6. check that email was sent or error occurs via docker logs slacker

Also check that you fill From and To email fields. Currently values from mail from and rcpt to are not used for comparision with rules.

Fill free to reopen this issue.

(For reference, the old version did not respond to <cr><lf>.<cr><lf>. Did confirm it was present in the hex file)
