I have setup the domain lefleurlingerie.com with a FQDN of lefleur.lefleurlingerie.com which points to a wordpress installation that all works pretty well. My problem is when wordpress tries to send an e-mail out for new users, authenticating users, receipts, contact forms and so forth. I believe this is due to the PHP mail() function not being setup correctly.

I've been through this guide http://library.linode.com/email/postfix ... 0.04-lucid but stopped at the Email Virtual Hosting and Sending Email Securely sections because I don't need to host e-mail and i hope to get it working before i worry about security.

I wonder if anyone has any tips for troubleshooting?

I've spent a day and a half reading docs and googling but I mostly end up trying other peoples solutions that don't work for me. I just don't know where to go from here.

If you need more information I'm happy to provide it.

Since you really didn't say what exactly you are having problems with (for example errors, etc) it is hard to give you any specific pointers. I would say start by looking at your email logs.

Is your issue because the FROM address is not what you expected it to be?
