一周过去了,我在 Google 上搜索和浏览 serverfault 都没有成功。所以,这是我最后一次机会来解决这个问题。

我有一个 powershell 脚本,当备份工作完成时,它会向某些收件人发送电子邮件。使用 smtp2go.com 等 smtp 服务器时,它可以正常工作。但是,我需要使用托管在 digitalocean 中的 postfix/dovecot 才能使其正常工作。

脚本如下:

########## TO CHANGE ##########
$from = "[email protected]"
$to = "[email protected]"
$subject = "Test"
###############################
$SMTPServer = "mail2.loche.com.ar"
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer) 
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential("[email protected]", "password")
$mailMessage = New-Object System.Net.Mail.MailMessage($from, $to)
$mailMessage.subject = $subject
$mailMessage.isBodyHTML = $true
$mailMessage.body = $body

#Added to remove certificate validation check, if needed
[System.Net.ServicePointManager]::ServerCertificateValidationCallback = { return $true }

$SMTPClient.Send($mailMessage)

备份服务器与 Postfix 服务器不在同一网络中。实际上,Postfix 服务器位于 digitalocean 中,我有许多来自不同客户的备份服务器,我需要使用相同的凭据来监控备份结果。

我收到的错误是:

Jun 18 11:22:17 loche postfix/submission/smtpd[1537904]: NOQUEUE: reject: RCPT from unknown[x.x.x.x]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<computername>

我允许 mynetworks = 0.0.0.0,但它充当开放中继,当然,没有人想要这样。

后配置-n
