Since the Antenna is right outside of your dwelling, are they actually paying you to rent the space the signal will be transmitting from? If not, you may ask them to pay you outright or have them fully isolate the signal from entering your dwelling. Otherwise, you can contact the Condo administration and ask for your "kickback" for housing such "dangerous" signals to your dwelling. Has anyone done this in the past?

This is why there would be a global payment system that mail servers would join... the user would purchase a minimum of 5-10$ of eStamps and would be distributed monthly to the providers. sender provider and payment provider would get 35% of the fee while 30% goes to the receiver provider. Problem solved.
Sender and receiver provider would make money while the actual sender is paying for it.

Surgemail already is micropayment ready... Just plug in your bank settings and you are ready to go.

Curious as to why you would need a secondary mail server for a small company when *IF* you purchase the right product, it can all be handled by one mail server. We use Surgemail and the load it can handle puts other commercial mail server software to shame.

Want to reduce false positives, and your friends, colleagues and email partners to ask their provider to support either Domainkeys or SPF. Once they get on the bandwagon, their mail will no longer get false positive flagged.

check to see if your provider is using SPF... If so, they end up blocking domains that does not have one or is spoofing a domain that does have SPF setup. This helps significantly to reduce the amount of junkmail.

Look at my mail server's spam status.
the RBL has blocked 95% of the spam out there.
57.5% had no SPF records. Looks like SPF has gained a lot of ground now... almost half of the Internet is now using it.
Using Surgemail, I do not need to use 3rd party anti-spam systems as the anti-spam is handled by the mail server itself. It handled 4 million messages in a month and does not break a sweat. I love this mail server and no other system can persuade me to switch... Support is incredible, service top notch... can not praise it enough.
