The corelan link above is to a program that uses a third party component to support SSL. POP Collector uses no third party components. If there were a free component available, I'd happily integrate it - but I am unaware of one, and as PC is free, I'm not going to purchase any components for it.
With regards to UTF8 - this is a reference to POP Collector? Do you have an example email that you could send me to test with? PC doesn't actually modify the contents of the message at all, so not sure why there should be an issue.
