I looked at the logs and didn't see any paypal activity, but I also noticed that the 70 lines of access log covered less than 1 minute, so I don't think any conclusions can be drawn from that.

I looked at the code for the points mod that does work with paypal, but it doesn't look llike it uses the IPN message. I don't know how it works without it.

I tried to go to https://removed.com using chrome this morning and got this message:

The webpage at https://a2s.in/ might be temporarily down or it may have moved permanently to a new web address.
Error code: ERR_SSL_VERSION_OR_CIPHER_MISMATCH

which is kind of what I was originally thinking, that there may be an SSL handshake issue between paypal and your server. I don't know how you'd go about debugging that. I think apache has an ssl error log, (if that's what you're using). ETA: or, as I think I mentioned earlier, maybe you can run an http server that allows access only to payment_gateway.php.
