亞馬遜SES從Debian上的後綴修改EC2實例無法發送電子郵件

Question

我被要求做一些系統管理員並將傳統PHP Web應用程序移動到運行Debian的Amazon EC2實例。我已經完成了這項工作，並且郵件已經成功從postfix發送。

之前的系統管理員擔心服務器未使用電子郵件中繼，並且使用SES的請求看起來很簡單。我使用Rackspace實例中的Mailgun實現了郵件中繼，雖然不是微不足道的，但我在幾個小時內完成了這個任務。

我還沒有找到SES過程非常簡單，我懷疑這是因爲我不熟悉使用證書。

起初，我成立了服務這裏使用說明 http://docs.aws.amazon.com/ses/latest/DeveloperGuide/postfix.html

• 彈性IP設置爲服務器的SMTP服務器
• 創建IAM用戶創建
• 證書，並獲得了SMTP用戶名和密碼在 電子郵件smtp.us-west-2.amazonaws.com
• 我創建了一個/ etc/postfix/sasl_passwd文件與

[email-smtp.us-west-2.amazonaws.com]：25用戶名：密碼

• 然後我跑

  postmap哈希：/等/後綴/ sasl_passwd

創建sasl_passwd.db

• /etc/postfix/master.cf沒有smtp_fallback_relay在它

• 我通過安裝創建的證書的apt-get安裝SASL2-bin和

  OpenSSL的REQ -x509 - 節點-days 365 -newkey RSA：2048 -keyout server.key -out server.crt這

，指着後綴這個在我的馬in.cf（在這篇文章的末尾）。

我使用sendmail通過Python

SENDMAIL = "/usr/sbin/sendmail" # sendmail location 

FROM = "andy@travelinsurancequotes.com.au" 
#TO = ["kirstie@travelinsurancequotes.com.au", "jason@slatescience.com"] 
TO = ["jason@slatescience.com"] 

SUBJECT = "Artog SMTP server is working!" 

TEXT = "Sending emails on the TIQ webserver is working" 

# Prepare actual message 

message = """\ 
From: %s 
To: %s 
Subject: %s 

%s 
""" % (FROM, ", ".join(TO), SUBJECT, TEXT) 

# Send the mail 

import os 

p = os.popen("%s -f %s -t -i" % (SENDMAIL, FROM), "w") 
p.write(message) 
status = p.close() 
if status: 
    print "Sendmail exit status", stat 

發送一封電子郵件，但我不斷收到超時錯誤的發送：

Feb 26 03:18:19 lamp postfix/error[23414]: 5DE3240508: to=<jason@slatescience.com>, relay=none, delay=0.02, delays=0.02/0/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to email-smtp.us-west-2.amazonaws.com[54.187.123.10]:25: Connection timed out 

我可以通過端口連接25

Answer 1

AWS EC2具有某種對郵件限制發送的..

我有這樣的錯誤，和亞馬遜的支持讓我填寫此表以去除限制。

https://aws.amazon.com/forms/ec2-email-limit-rdns-request

我希望這有助於
