I'm a British PHP developer and Linux sysadmin based in the French alps.
I'm the architect and chief developer on Smartmessages.net, an enterprise-level mailing list management system at http://www.smartmessages.net/ run by my company in the UK, Synchromedia (http://www.synchromedia.co.uk). I'm very active on GitHub (https://github.com/Synchro) - I'm the maintainer of PHPMailer (probably the most popular code in existence for sending email) and a committer for LESS.js.
You can also find me on Twitter as @SynchroM and LinkedIn at http://www.linkedin.com/profile/view?id=3765425
If you wish to contact me outside EE, please use the contact form on that site - I'm always interested in other development and sysadmin work.
If you're calling mail() yourself, you're doing it wrong. Use PHPMailer instead: https://github.com/PHPMailer/PHPMailer/
