![使用外部 SMTP 服务器设置 Postfix](https://linux22.com/image/988517/%E4%BD%BF%E7%94%A8%E5%A4%96%E9%83%A8%20SMTP%20%E6%9C%8D%E5%8A%A1%E5%99%A8%E8%AE%BE%E7%BD%AE%20Postfix.png)
我正在尝试在 Ubuntu 14.04 上设置 postfix 以使用外部 SMTP 服务器。
我安装了libsasl2-modules
来处理身份验证。
我创建了我的凭证文件:
sudo vim /etc/postfix/sasl_passwd
使用:
[mail.mydomain.com]:587 username:password
创建哈希数据库:
sudo postmap /etc/postfix/sasl_passwd
使用此设置在/etc/postfix/main.cf
:
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
#myhostname = web.mydomain.com
mydomain = mydomain.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = www.mydomain.com, web.mydomain.com, localhost.mydomain.com, localhost
relayhost = [mail.mydomain.com]:587
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
# enable SASL authentication
smtp_sasl_auth_enable = yes
# disallow methods that allow anonymous authentication.
smtp_sasl_security_options = noanonymous
# where to find sasl_passwd
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
# Enable STARTTLS encryption
smtp_use_tls = yes
# where to find CA certificates
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
但是,每当我发送测试邮件时,身份验证都会失败,因为postfix
没有使用我的凭据,sasl_passwd
而是使用当前用户。请检查我的/var/log/mail.log
:
Mar 4 09:10:20 web postfix/smtp[9214]: 4087042522: to=<[email protected]>, relay=mail.mydomain.com[xx.xx.xxx.xx]:587, delay=4.9, delays=4.8/0.01/0.12/0.01, dsn=5.0.0, status=bounced (host mail.mydomain.com[xx.xx.xxx.xx] said: 550-Verification failed for <[email protected]> 550-No Such User Here 550 Sender verify failed (in reply to RCPT TO command))
Verification failed for <[email protected]>
当我想在 sasl_passwd 中使用我的用户名:密码时。
我找不到有关如何深入研究这个问题的文档。为什么postfix
不使用 sasl_passw 文件?

对于遇到同样问题的人,我只需在我的 ISP 上为机器中的每个用户创建电子邮件帐户即可发送电子邮件([email protected]
、[email protected]
和[email protected]
)并正常工作。
