Set Postfix + SMTP-AUTH + TLS + Openwebmail under Ubuntu7.10

In the previous article, when OutlookExpress is used to receive a mail, the following error occurs: an error occurs when you log on to your email server. Your password is rejected. Account: 'Your mail Server', server: 'Your mail Server', communication protocol: POP3, Server Response: '-ERRchdirMaildirfailed', connection port: 110, security (SSL): No, server error: 0 × 800CCC90, error code: 0 × 800

In the previous article, the following error occurs when Outlook Express is used to receive emails:

An error occurred while logging on to your email server. Your password is rejected. Account: 'Your mail Server', server: 'Your mail Server', communication protocol: POP3, Server Response: '-ERR chdir Maildir failed', Port: 110, security (SSL): No, server error: 0 × 800CCC90, error code: 0 × 800CCC92

Later I confirmed it on Google because the installation of Courier-POP3/Courier-IMAP does not support mbox gs' only support Maildir format, and Falko Timme has been declared before, this problem was not detected at the beginning, so we had to use dovecot in mbox format. The method can be referred to below: Install Dovecot + Sendmail + OpenWebmail in Ubuntu

We only need to install Devecot. The operation reference is as follows:

1. Install the dovecot Kit

Sudo apt-get install dovecot-common dovecot-pop3d

2. Set/etc/dovecot. conf

Protocols = pop3

Disable_plaintext_auth = no

Ssl_disable = yes

3. Start dovecot

/Etc/init. d/dovecot start

4. Test

Telnet pop3_server 110

Auth

User user_name

Pass user_password

If OK is displayed, the operation is successful.

Tested, OK!
