[Elecraft] Mail list not working?

[Brendon Whateley]

Bill,

I have extensive experience getting email delivered in a commercial setting
for our product that sends 1000s of status and report emails per day. While
it is wrong to blame the actual recipient, delivery problems are almost
always related to the recipient's email service, often an ISP of company.

We see this every day where we can see that our email servers have
delivered the email to the recipient's email server and yet the user never
has it delivered to his or her inbox. The usual reason is related to
anti-spam measures that ISPs employ. Most now discard a good percentage of
inbound email without even bothering to place it in a spam folder.
Sometimes, like gmail does all the time, the email is quarantined either
for a period of time or indefinitely pending manual release. This is often
done to see if this is a an email that is being sent to many other
recipients at the ISP, in which case it is probably spam.

Others are more helpful, sending our servers a rejection message saying
things line "Blacklisted" or "violates local email policy" or something
similar. Other times it is a temporary error of some sort and we get
rejections saying "excessive email rate", "user not found" or "mailbox
full". We can often see that this is an error, because after some number of
attempts or a few days, the "User is again found".

My point is that in all these cases, the delivery is failing on the "user's
side of the internet" even if they have no direct control of the receiving
email server. And short of coordinating with the ISP to get whitelisted,
there is not a lot the sender can do.

Regards,
