This line tells us that the email has originated from a blacklisted IP address. Following the link, http://www.spamcop.net/bl.shtml?193.224.241.94, takes us to an information page provided by spamcop.net. It states that the IP address supplied has been reported a number of times and that it has been found to send email to email addresses planted on the Internet deliberately as bait in spam traps.

The definition of RBL as offered by Kadow's Internet Dictionary is

Realtime Blackhole List. A list of open mail relays and rogue sites, maintained by Paul Vixie. Subscribers to the RBL reject all mail and/or connection attempts from RBL'd IP addresses, effectively cutting off irresponsible/incompetent domains from the rest of the Internet. Subscription is completely voluntary, details are at http://maps.vix.com/rbl/.

3. Does the content of the email make sense? Are there spelling, grammar and logic mistakes?

The HSBC are unlikely to send out emails that are riddled with such errors so it's another easy check to carry out as long as your own grasp of the language is sufficient.

We've seen from the header information that this is not true.

This sentence doesn't make sense and is grammatically incorrect. The point it is attempting to convey is done so poorly and without clarity. In matters of importance, the language used tends to be very concise so as to reduce the likelihood of confusion.
