Let’s Encrypt
I’ve written some posts on Let’s Encrypt but the most frequently question is how to auto renew a certificate every 90 days.
Disclaimer
This is my mini how-to, on centos 6 with a custom compiled Python 2.7.13 that I like to run on virtualenv from latest git updated certbot. Not a copy/paste solution for everyone!
Cron
Cron doesnt not seem to have something useful to use on comparison to 90 days:
Modification Time
The most obvious answer is to look on the modification time on lets encrypt directory :

Iterator
a few months ago, I wrote an article on RecursiveDirectoryIterator, you can find the article here: PHP Recursive Directory File Listing . If you run the code example, you ‘ll see that the output is not sorted.
Object
Recursive Iterator is actually an object, a special object that we can perform iterations on sequence (collection) of data. So it is a little difficult to sort them using known php functions. Let me give you an example:
$Iterator = new RecursiveDirectoryIterator('./');
foreach ($Iterator as $file)
var_dump($file);
object(SplFileInfo)

Part of my day job is to protect a large mail infrastructure. That means that on a daily basis we are fighting SPAM and try to protect our customers for any suspicious/malicious mail traffic. This is not an easy job. Actually globally is not a easy job. But we are trying and trying hard.

The last couple months, I have started a project on gitlab gathering the malicious ReplyTo from already identified spam emails.

Spammers can alter their ReplyTo in a matter of minutes!
