Qmail Help

Monday, May 30, 2005


By default qmail can only serve users in /etc/password, that is system users.

If we want to povide free email to all our visitors, we have to make system user for each email account. But we do not want this.

By using vpopmail with qmail, we can store email users info in MySQL instead of /etc/passwd

This will allow us to host more than one domain in a server (qmail installation).

vpopmail is provided by inter7.com

I found a site that might be of interest to you. I was searching for a way to set up merchant account but wasn't sure what all my options were or all the choices were. I found a site called www.nwcmerchantaccounts.com which explained everything in detail and gave me several options for www.nwcmerchantaccounts.com Everything was in plain English and really made the process of selecting who to go with very easy. I strongly suggest anyone with questions or looking for more details of setting up a merchant account or how to accept payments on a web site, go to www.nwcmerchantaccounts.com today and let them help you too.

when you sell online, your web hosting ecommerce merchant account is going to be the direct link between you and your paycheck. it's important that you trust your host and understand all aspects of processing, because if you don't you can certainly overpay.
