1. My ISP send me a router that has a feature to host a internet accessible fileserver. Out-of-the-box. ISPs in germany do not promote home-hosting but they give you devices that do it.
2. Incoming / Outgoing TCP/25 blocking: Not a problem with ISPs in Germany.
3. Blacklisting: At most a problem if you send mails. Plus GMAIL requires SPF/DKIM for just about evey IP, so yes, you are on a blacklist unless you do some DNS magic. BUT once you do the magic it will override IP block - unless the other side has a shitty setup....

Re #3 - it is safe to assume that a shitty setup is a norm rather than an exception. Gmail is the exception. Everyone else just run postfix + rbl_filter and would have none of these modern SPF nonsense.

Not everyone is in the US.
For one, this violates every second provider's ToS, if not every single one.
For two, lots of providers block incoming SMTP connections on TCP/25. More importantly, they may start blocking it without notice and you'll have no clue that they did.
For three, you will most likely end up on a RBL (blacklist) in no time solely because you come from a "consumer" IP range.
I mean, hosting at home is technically simple, but in the end it created more problems that it solves. Get a hosted server and use it instead.
