I want to send data to an emailaddress and save it into a MySQL database (PHP). What is the easiest way to do this? (no form post, no curl etc., just email)
If you can access the email using POP just have a process checking the email with POP functions and sending everything to your database
Also you could use php IMAP support
Assuming you know how to save the data to mysql already, you will need access to a mail server, either your own, a webhosts, or you could use a free one such as Gmail, or Hotmail.
You can then use PHP's IMAP functions (which can access POP too) to access the mail. Articles which may help you with this: PHP imap info and a tutorial on creating PHP webmail
there are a few ways.
use a postfix alias script, basically, postfix receives your mail, and then runs it through a script of your choosing. The contents of the mail appear in STDIN - then you can do as you please with the contents of the mail.
Use a custom mail server like apache james, that is designed to process mail, and 'do something with it'
{A good one I found recently was in the google labs - http://freshmeat.net/projects/subethasmtp} - looked really good.
pls bear in mind that email is not a guaranteed protocol, if you are trying to do app-to-app messaging, then there are probably better ways!
Hope this helps., ace
There is a slicehost step-by-step tutorial that takes a unix based machine, installs postfix on it, sets it up to use MySQL and configures it to accept virtual users and serve/receive email from multiple domains.
The set up is clean, fast and secure. Life is good, eh?
If your server doesn't have imap but you have an outside system which does have cron you can write a page that checks the email account and loads the data into MySQL then set up a script on a machine that does have cron to wget the mysql page once every X minutes where X is how frequently you want to load data.
Alternately if you know the emails will load quickly you can set up small one field table in your DB with a time stamp. Each time your PHP script runs it checks the time stamp and if it's more than 5 minutes old it calls the email loading script before loading the web page.
