we have a spare server with root access that we want as our email server. it needs to send PHP email with the mail function to new accounts, lost passwords, etc instantly, but also needs to batch process a newsletter every couple of weeks.
We have over 6 million email addresses on file, but a large percentage are now most likely too old and will bounce.
We also need the following:
1) manage the bounced emails properly
2) anti spam, domain keys, spf records, etc
3) software/freeware/monitoring programs so that we can easily see how the email server is running and easily diagnose problems.
Please do not waste our time, we know the basics to do this ourselves but will need more EXPERT knowlege/help here hence why we are willing to pay.
We are ready to start right away. we have MSN and skype.unix servers.
