Custom Mailer frontend needed ASAP

I require a linux mailer frontend. We already have a custom MTA so we are looking for someone to do the front end of it. We are looking for someone that has something done already or if not you must be able to deliver withing 7-10 days or less. Below are some basic requirements. - Ability for direct SMTP connections to remote MX servers. - Ability to send out HTML e-mails. - Ability to include embed images in HTML messages. - Mechanism to faciliate auto unsubscribes (eg. one click) from a mailing list. - Filter conditions (eg. by country or destination domain). - Ability to validate e-mail addresses before sending them (eg. do a MX lookup on domain). This is required to eliminate undeliverables. - Ability to set priority of SMTP engine. - Ability to specify number of threads to use. - Ability to sort and randomize e-mails to specific domains. We don't want to get blocked by a remote server due to a large amount of e-mails coming in at once. - Ability to report successful deliveries and unsuccessful deliveries. - Ability to specify keywords (eg. **name**) for substitution. - Ability to view progress in real-time and stop an e-mail blast. - Ability to track opens and clicks (eg. using embedded pixels). - Ability to import a list using CSV / ASCII files. - Ability to resend e-mails if they failed. - Ability to use multiple transmission methods. - Ability to view real-time reports of campaigns.
