sSMTP 不再有效 - “无效响应：501 5.5.4 HELO/EHLO 参数 MYEMAILADDRESS@gmail.com 无效，正在关闭连接。”

Question

正如标题/标签所说，我在 Linux 上为 PHP 服务器运行 sSMTP。

每当我尝试发送电子邮件时，我都会收到这些错误（不会出现在 PHP 中，仅出现在日志/“sudo service sendmail status”或“sudo service php5-fpm status”中）

来自 /var/log/mail.log

我的 /etc/ssmtp/ssmtp.conf

#
# Config file for sSMTP sendmail
#
# The person who gets all mail for userids < 1000
# Make this empty to disable rewriting.
root=MYEMAILADDRESS@gmail.com

# The place where the mail goes. The actual machine name is required no
# MX records are consulted. Commonly mailhosts are named mail.domain.com
mailhub=smtp.gmail.com:587

# Where will the mail seem to come from?
#rewriteDomain=

# The full hostname
hostname=MYEMAILADDRESS@gmail.com

AuthUser=MYEMAILADDRESS@gmail.com
AuthPass=[removed]
UseSTARTTLS=YES
# Are users allowed to set their own From: address?
# YES - Allow the user to specify their own From: address
# NO - Use the system generated From: address
FromLineOverride=YES

我的重新定义

root:MYEMAILADDRESS@gmail.com:smtp.gmail.com:587
localusername:MYEMAILADDRESS@gmail.com:smtp.gmail.com:587

Answer 1

经过多年的努力，我终于系好安全带并从 Arch Linux 的 wiki 文章中复制了用于 Gmail 和 SSMTP 的配置，并且最终成功了！伙计们，请务必三重检查您的配置！

# The user that gets all the mails (UID < 1000, usually the admin)
root=username@gmail.com

# The mail server (where the mail is sent to), both port 465 or 587 should be acceptable
# See also http://mail.google.com/support/bin/answer.py?answer=78799
mailhub=smtp.gmail.com:587

# The address where the mail appears to come from for user authentication.
rewriteDomain=gmail.com

# The full hostname
hostname=localhost

# Use SSL/TLS before starting negotiation
UseTLS=Yes
UseSTARTTLS=Yes

# Username/Password
AuthUser=username
AuthPass=password

# Email 'From header's can override the default domain?
FromLineOverride=yes

我的ssmtp.conf包含hostname=xxx@gmail.com，我改成hostname=localhost，问题就解决了。
