Настройка postfix и dovecop для пересылки почты (Plaintext Authentication)

# yum install -y \
dovecot 

# chkconfig --level 345 dovecot on

# service dovecot start

# cp /etc/dovecot/dovecot.conf /etc/dovecot/dovecot.conf.bkp
# cp /etc/postfix/master.cf /etc/postfix/master.cf.bkp


# vi /etc/dovecot/dovecot.conf
protocols = imap pop3

login_greeting = POP3/IMAP server ready.

listen = *

# service dovecot restart

#  netstat --inet -lpn | grep dovecot

Check that it's allowing remote logins
# nc sysadm.ru 143
a login "username" "password"

// В моем случае это:
a login bill.gates 1234

* BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed.
a NO [PRIVACYREQUIRED] Plaintext authentication disallowed on non-secure (SSL/TLS) connections.

// Разрешаем plaintext аутентификацию
disable_plaintext_auth = no

mail_location = maildir:~/Maildir


# nc sysadm.ru 143
a login "username" "password"

// Check that it finds INBOX
b select inbox
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.
* 2 EXISTS
* 2 RECENT
* OK [UNSEEN 1] First unseen.
* OK [UIDVALIDITY 1387822975] UIDs valid
* OK [UIDNEXT 3] Predicted next UID
* OK [HIGHESTMODSEQ 1] Highest
b OK [READ-WRITE] Select completed.



============================================
Нужно проверить:

Забрать письмо из консоли:
ns sysadm.ru 110
USER bill.gates
PASS 1234
list


retr 1

dele 1

quit



============================================


После подключаю thunderbird.
Почту удается успешно забрать.
При попытке отправить сообщение, получаю сообщение.

An error occurred while sending mail. The mail server responded:  5.7.1 : Relay access denied. Please check the message recipient [email protected] and try again.
