Hi, let me introduce myself
I am Lenny, and I=E2=80=99ve been in the OSS space for over 15 years =
now.
Currently, I am the Apache Shiro PMC chain, and a contributor to many =
Apache and other Open Source (Jakarta EE and related) projects.

And to the problem at hand=E2=80=A6
I have been running my own email server for my family and friends for =
around ~30 years. It has evolved over the decades.
Generally, I am pretty happy about things, except issues do come up from =
time to time.
Currently, I am facing one of those issues, which is a recurring issue.
My inbound email providers for relay, store-and-forward and backup are =
failing me from time to time.
I have used ImprovMX, which I had mystery problems with that they could =
not fix.
Now I am with dynu.com <http://dynu.com/>. Dynu has 2 issues: sometimes =
the email queue gets resend (I get a bunch of dupliates)
I get a bunch of spam emails that don=E2=80=99t get filtered probllely.

I am ready to bring inbound email backup / spam / queue relay server =
in-house.

What are my requirements? Relay SMTP server with the following features:
- Accept email via unencrypted and SSL
- Relay this email via SSL
- Filter / bounce spam if it doesn=E2=80=99t pass SPF or DKIM
- Filter / bounce spam if it=E2=80=99s originating IP or domain is =
listed in any RBL lists (checked real-time)
- Filter / bounce spam if the links inside the it are listed in any RBL =
lists (real-time checking)

Does Apache James an appropriate tool to use given these requirements?
If not, can you recommend another tool that matches what I am looking =
for?

Thank you very much!=
