I'm happy to say that the net as we know it is more secure today than it was
years back. I can speak to this security first hand due to the list
problems. Lets examine what's really going on.
1. Anyone who wants to post can.
2. Some people were always receiving mail from the lists. These people have
problems that I'll get into in a moment.
3. Many people could not get posts from the list.
4. Some people still can't get posts from the list.
What's going on? The answer is security. When the HoF mail server tries to
send a message to someone it attempts to connect to port 25 on their box and
pipe the message to them directly. The actual process is :
HoF: hi, I'm the HoF mail server with a message for you.
recipient: Well, you may be a spammer. let me check your DNS info to see if
your really who you say you are.
HoF: ok, I'll wait
recipient: OK, your you. let me see the message.
HoF: here it is.
recipient: OK, it's for someone here. I'll deliver it. Thanks
HoF: your welcome
Now due to a DNS change, the info for the HoF server was not correct. This
is changing slowly as DNS servers cycle, but takes time. Because of this,
many messages are being rejected by the recipient. This means that:
1. Those who have always been getting mail do not have proper security on
their mail servers or their DNS changes really, really fast (probably the
former).
2. Those who are receiving messages now but had a lull have good security on
their mail servers and their DNS has cycled.
3. Those who have not gotten messages have slower DNS server cycle rates.
As time goes by and servers cycle, people will start getting their mail
again and happiness will reign. Tell your friends that happy days are coming
again really soon. :)
For those who want to see the actual error message that is recorded with the
message, here it is:
Defer-Reason: Couldn't establish SMTP connection on port 25
