The -V option is used to search for non-matching ones.
[vagrant@localhost ses]$ grep gmail sendmail.cgi
$to = ‘hoge@gmail.org’;
[vagrant@localhost ses]$ grep -v print sendmail.cgi
なるほど、一致しないものね。使い勝手がいいですね。

npm install aws-sdk –save
npm install の–saveオプションって何？
-> パッケージをインストールして、package.jsonに書き込む
[vagrant@localhost ses]$ npm -v

AWS credentialsを設定し、メール送信する
var AWS = require('aws-sdk');
AWS.config.update({region: 'us-east-1'});
var ses = new AWS.SES();
var params = {
Destination: {
ToAddresses: [ 'hoge@example.com' ]
},
Message: {
Body: {
Text: {
Data: 'hello SES',
Charset: 'utf-8'
}
},
Subject: {
Data: 'Hello',
Charset: 'utf-8'
}
},
Source: 'jiro@example.com'
};
ses.sendEmail(params, function(err, data){
if(err) console.log(err, err.stack);
else console.log(data);
});
jsonか。。
mkdir ${dirname} && cd $_
コマンドラインで「$_」は一つ前の引数
[vagrant@localhost test]$ echo hoge && echo $_ hoge hoge
$_でhogeを引っ張てきている
mkdirでやると、
[vagrant@localhost test]$ mkdir ses && cd $_
[vagrant@localhost ses]$
おお、なんか素晴らしいですね。
Amazon SES
Amazon Simple Email Service (SES) is Amazon’s email sending service.
Weight charge system, no minimum fee required.
Free quota is 62,000 transmissions / month from EC2 and 1,000 receptions / month.
Amazon SES Sandbox
– In order to prevent fraud and to avoid SPAM accreditation from ISPs, new user accounts are placed in a sandbox (environment for verification purposes) and limited in part by behavior.
– Emails can be sent and received only from verified email addresses or verified domains.
– You can send up to 200 messages per day, up to one message per second.
– If you move the account out out of the sandbox, it will work in the unrestricted environment.
– It will take 1 business day to proceed.
Identity
– Case- insensitive combination of domain and email address. (user@example.com and USER@example.com have different identities)
Domain Key Identification Mail(DKIM)
– It is a standard for the ISP to prove that senders have signed e-mail messages so that they are genuine and have not been tampered with by a third party during transmission.
fsockopen – smtp
Open an internet connection or Unix domain socket connection.
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if(!$fp){
echo "$errstr ($errno)<br>\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: www.example.com\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)){
echo fget($fp, 128);
}
fclose($fp);
}
MX record
An MX record is a record that defines the mail destination host name for the target domain.
The mail transfer destination host name needs to be registered in A record. Refers to the A record set by the customer and acquires the IP address of the mail server. Therefore, please note that it will not operate normally if A record is not set.
配送先のメールサーバーを決定する際に使用。
ということは、配送先メールサーバーのAレコードって認識であってる？
あれ、結構複雑だなー
git fetch
pull = fetch + merge origin/master
What is “git fetch”?
For git, there are two repositories: remote and local. Fetch is a command that brings the latest information from the remote repository to the local repository. Fetching does not mean that the file is updated like pull. Only the local repository is updated.
