Description

As per the title - mails can't be deleted via POP3 DELE.

Steps to reproduce:

• build the project (spring app in this case, but I don't think that matters)
  • git clone https://github.com/apache/james-project
  • cd james-project
  • docker build -t james/project dockerfiles/compilation/java-8
  • docker run -v $HOME/.m2:/root/.m2 -v $PWD:/origin -v $PWD/dockerfiles/run/spring/destination:/spring/destination -t james/project -s HEAD
  • cd dockerfiles/run/spring/destination/
  • unzip james-server-app-3.5.0-SNAPSHOT-app.zip
  • cd james-server-app-3.5.0-SNAPSHOT/bin
  • ./run.sh
• add a user
  • ./james-cli.sh test@localhost test123
• send a mail to that user
  • nc -C localhost 25
  • ...
• login via POP3 and fetch the mail
  • nc -C localhost 110
  • USER test@localhost
  • PASS test123
  • LIST
    • (should list only one mail, the one you sent before)
  • RETR 1
    • (should display said mail's contents)
  • DELE 1
    • (should display `+OK Message deleted`)
  • LIST
    • (should display `+OK 0 0`)
  • QUIT
• login via POP3 again
  • LIST
    • (oops, the mail is still there, just like before)
