Thread: Authentication in POP3
Started 1 month ago by shreedhan
Hi, I was recently working with POP3 and have few questions about the working of authentication of POP3. I went through few RFCs and found out that POP3 supports SASL authentication mechanisms and TLS as well. How does SASL PLAIN work without using TLS ? I tried using base64 encoded 'username' + '\0' + 'username' + '\0' + 'password'. But it's not authorizing me. What's the problem here...

Dear Shreedhan, I can partly help you: echo -e -n "\0username\0password" | base64 gives you the encoded login telnet mypopserver 110 Escape character is '^]'. +OK Dovecot ready. AUTH PLAIN thestringfromthecommandabove +OK Logged in. Not very safe, because you can decode the string with base64 -d The TLS variant is much more complex, so that is something I can answer you, ...

Do you have dovecot running for pop3s only? You want secured pop3 right? Look at your /etc/dovecot.conf file. Code: # Protocols we want to be serving: imap imaps pop3 pop3s managesieve # If you only want to use dovecot-auth, you can set this to "none". protocols = pop3s Edit: Whoops, didn't realized in was in the programming section. Can't delete my entry, sorry.
