我已經使用Postfix和Dovecot配置了Ubuntu 12.10服務器。儘管如此，當我嘗試使用Rails Web應用程序發送電子郵件時，我遇到了SASL登錄身份驗證問題。SASL LOGIN身份驗證失敗：在Ubuntu上使用Postfix和Dovecot的Rails上的身份驗證機制無效12.10
使用RoundCube郵局，我得到這個日誌時，我發送一封電子郵件：

dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient}
而且我Dovecot的配置文件，我的dovecot.conf如下：
auth_mechanisms = plain cram-md5
auth_verbose = yes
base_dir = /var/run/dovecot/
info_log_path = /var/log/dovecot.info
log_path = /var/log/dovecot
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/var/vmail/%d/%n
passdb {
args = /etc/dovecot/passwd
driver = passwd-file
}
protocols = imap pop3
service auth {
executable = /usr/lib/dovecot/auth
user = root
}
service imap-login {
chroot = login
executable = /usr/lib/dovecot/imap-login
user = dovecot
}
service imap {
executable = /usr/lib/dovecot/imap
}
service pop3-login {
chroot = login
executable = /usr/lib/dovecot/pop3-login
user = dovecot
}
service pop3 {
executable = /usr/lib/dovecot/pop3
}
ssl = no
userdb {
args = /etc/dovecot/users
driver = passwd-file
}
valid_chroot_dirs = /var/spool/vmail
protocol pop3 {
pop3_uidl_format = %08Xu%08Xv
}
auth default {
mechanisms = plain cram-md5
passdb passwd-file {
args = /etc/dovecot/passwd
}
userdb passwd-file {
args = /etc/dovecot/users
}
user = root
socket listen {
client {
# The client socket is generally safe to export to everyone. Typical use
# is to export it to your SMTP server so it can do SMTP AUTH lookups
# using it.
path = /var/spool/postfix/private/auth-client
mode = 0660
user = postfix
group = postfix
}
}
}
然後，在Rails應用程序的郵件配置如下：
config.action_mailer.smtp_settings = {
:address => "ks400054.kimsufi.com" ,
:port => 25,
:domain => "ks400054.kimsufi.com" ,
:user_name => "[email protected]" ,
:password => "THE_CORRECT_PASSWORD",
:authentication => :cram_md5,
:enable_starttls_auto => true,
:tls => true
}
我不不知道爲什麼我不能使用Rails webapp登錄。
我錯過了什麼？這是配置上的東西嗎？
