Al,
Many thanks for the explanation. I now understand the problem and what is
happening. Exactly what was needed after I spent over an hour reading all
sorts of info this morning ... and got more and more confused!
Cheers,
John GW4SKA

Subject: Re: [RTTY] This is why you are having trouble with the reflector
I explained this over on TT.
The explanation is complicated but let me see if I can distill it down
here: A fairly common technique to reduce spam is to not deliver emails
from servers if that server is not listed as authorized to send on behalf
of a domain (e..g. yahoo.com). The decision whether or not to publish
this information is optional, as well as the decision of what to do with
the information if it is available.
To use yahoo.com as just one example, it has decided to implement a
variant of this technology. It publishes to the internet a list of IP
addresses that are allowed to send email claiming to originate from
yahoo.com. The problem occurs because contesting.com sends out its emails
as claiming to come from the sender of the post. So joeham@yahoo.com
posts to the RTTY reflector. Contesting.com sends out his post to all
subscribers of the list, including billham@gmail.com. Gmail has decided
to implement spf (that's the name of one variant of the technology
described above) and when their incoming email server receives a delivery
attempt from contesting.com, it checks with yahoo.com to see if the server
at contesting.com is on yahoo's list of authotized servers. It's not, so
gmail refuses delivery of joeham's post. No spam, no junk email, nothing
at all gets delivered to the gmail user.
The only practical fix for this problem is to reconfigure contesting.com
to send out email with the FROM: clause as being a contesting.com email
address and not the address of the post originator. It makes replying
directly to the originator difficult, but if the only other choice is no
delivery at all, then it seems like a reasonable compromise.

I have three email accounts registered with this reflector-icloud, gmail
and
webmail.wit.edu. Only the icloud.com got the message of hold due to
bounces.
I don't think it has anything to do with only sending a message to the
reflector but receiving. I haven't sent a message to this reflector for
quite awhile up until this message.

Can someone explain what, if anything, I can do to avoid this problem in
the
future?
I have read the posts and looked at other information on the internet. My
mail address is not Yahoo, Hotmail etc. so is the problem with the
original
sender of the mail?
Keep it simple if possible ... I have never understood all the
complexities
of how email works .. like many others, I am just a computer *user* !

Bill,
There is no fixing this. The companies have made a stupid change to
their
email systems. The solution is to not use yahoo, hotmail, etc. There is
a huge thread on this at Towertalk. It is effecting lots of people.

So because your email address domain (e.g. yahoo.com) does not match
the
sending domain (e.g. contesting.com) a whole bunch of servers are
bouncing
your reflector emails. And the reflectors are unsubscribing you because
of
too many bounces.
REPLY:
Actually, nobody is getting unsubscribed but rather being put on a
temporary hold status because of too many bounces. You need to talk to
your ISP (yahoo.com, hotmail.com or whoever) and get this rectified.
In the meantime, if you email me direct I will re-instate your service
immediately, but of course, the same thing could happen again if the
problem with your ISP is not fixed.
Also please note that with some ISPs (such as mine) you will not see
your
own messages to the reflector. They do this to save bandwidth, so they
say. My ISP is based on Google, and I I am told that gmail does the same
thing. You can overcome this by cc'ing or bcc'ing yourself if you wish.
