Receiving mail directly will be more possible, but tricky. You will need to use a dynamic DNS system. Also do consider uptime and reliability. In the old days, if one MTA couldn't reach another it would hold stuff in its queue for four or five days. Now, most MTAs appear to be configured to give up after 24 hours. So if your mailserver is down for a day, mail will be bounced and never delivered to you.
In which case those mail systems are not in compliance with the RFCs.
RFC 2821 Section 4.5.4.1 says:
Retries continue until the message is transmitted or the sender gives
up; the give-up time generally needs to be at least 4-5 days. The
parameters to the retry algorithm MUST be configurable.
ie. 4-5 days is the /minimum/ time to hold messages in the queue and
keep retrying.
