将服务器从Ubuntu 10.04升级到12.04后,postfix不再通过sendgrid.com发送电子邮件.大约6个月前我跟踪了
this guide,在升级之前一切都很顺利.现在它似乎没有使用sendgrid进行身份验证.
May 22 10:19:55 server postfix/smtp[3844]: 983B11C5DA: to=<to address>,relay=smtp.sendgrid.net[174.36.32.204]:587,delay=0.05,delays=0.01/0/0.04/0,dsn=5.0.0,status=bounced (host smtp.sendgrid.net[174.36.32.204] said: 550 Cannot receive from specified address <sendgrid username>: Unauthenticated senders not allowed (in reply to MAIL FROM command))
这是来自postconf -n
