What means Outlook shoudn't send directly to MX?
It means that rather than having your Outlook mail client directly contact
the mail servers (MX hosts) at, say, Microsoft, you should instead send
your email via the mail servers at your ISP and have *them* relay the mail
to Microsoft for you.
Most legitimate desktop clients behave this way. Having some random
desktop sending email directly to somebody's mail server rather than
sending it via the desktop's ISP's mail server is how spam zombies behave
- they are trying to avoid any filtering, antiforgery or rate control
measures in place at the ISP's mail server - so such traffic is pretty
much rejected by everyone these days.
I won't go into someone running a mail server at home here.
May it be the result of outgoing and incoming servers being the same??

No, it's generally the sign of a spambot. I don't know if any common
legitimate mail client these days can be configured to do domain MX
lookups for direct delivery in the first place.
I keep all messages, including spam, and now when looking into messages,
I'd say that mostly there are flaged as spam messages which really are
not and very seldom any real spam. That seems rather weird to me.
I'd like to ask later from my ISP, but first I need to know what's
wrong, as else most likely I'dnt get any reply.
Well, the two things I noted - they've lowered the threshold at which a
message is considered spam, and don't put a big value on bayes saying
"it's not spam" - may be a factor.
The blacklisting is often a problem, as sometimes my messages have been
rejected in USA, just because someone of my ISP 500.000 clients has sent
spams. Is it ISP to blame and punish with blacklisting, if there may be
some bots working?
The ISP's mail servers shouldn't get blacklisted, just the IP addresses
that ISP assigns to their customers.
