Long time ago, i created 2 jobs in Scriptlance for creating an Antispam Server using postfix and other modules. The AntispamServer acts as Relay between the internet and internal mailservers and relays are allowed only for the domains specified. There is a small webinterface made in Php to manage the postfix,spamassasin and others.

more details of the project was given here, when it was initially created

The job was handled by a very talented programmer/server admin 1 year ago and the job was completed to extreme satisfaction.

now i want to upgrade this facility and provide more options to it. Unfornuatly the old programmer cannot continue to work due to health issues , so im looking for someone to take over this upgrade.

The Server is working extremely well now , except for some minor bugs.

the new task includes the following

0. Study the current enivironments
1. Fix all the minor bugs
2. Currently the blacklist is not very strong , and can give lot of false positives, i need to improvise on this.
3. the logs are stored in mySQL . i need a proper reporting tool with search to locate a proper tool.
4. ability to delete queues or particular queued postfix email through current webbased admin(made in php, currently only lists the queue)
5. improvise on the spam catching.
6. Provide redirect of spam to external mail boxes like to a gmail box etc. instead of sending tagged spam to our internal mail server.
7. currently the blacklists are global and not per domain. i want to have per domain , where each domain can manage their own blacklists.

im looking for people who have worked on linux server and mail servers specially Postfix. Since you will be working on live server which has actual clients on it. you will need to have great recommendations or reviews from your previous jobs. The jobs will be properly planned , any backups of current setup, need to be copied on a different server and all testing will be done there. once functional and tested it will be installed on the production.
