HELO_DYNAMIC_IPADDR

[Wolfgang Jeltsch <je...@Informatik.TU-Cottbus.DE>]

Hello,

what does HELO_DYNAMIC_IPADDR mean?  Why is it rated that high?

The reason behind my question is that most of my e-mails seem to get 
HELO_DYNAMIC_IPADDR assigned to them.  In the From: field, I typically use an 
address which belongs to a domain registered by me and pointing to my own 
server while I’m sending my mails via my DSL provider’s SMTP server.  Since 
my provider seems to do sender rewriting, I’d say that the domain of the 
address in the From: field shouldn’t be an issue.

Any help would be greatly appreciated.

Best wishes,
Wolfgang

Sounds like you've got a broken trust path then.

This test should stop with the machine that delivered mail to your
network, it should not apply further out.

Of course, if SA's guesses about your network boundaries are wrong, it
will obviously get the wrong result. This is typical if your mailserver
is NATed.

I don’t quite understand this.  If the mail originated from a node in the 
provider’s network than this node isn’t necessarily a host with a dynamic IP 
address.  Well, in my case it is but what’s the problem with this?  Am I not 
allowed to send an e-mail from my computer at home (which will always have a 
dynamic IP address)?  If I setup SMTP auth on my own server, the mail still 
originates from my computer at home.  It’s the same situation as sending the 
mail via my DSL provider’s SMTP server.

Meanwhile I realized that not every mail I send the way I described suffers 
from the HELO_DYNAMIC_IPADDR problem but the mail I attached to my other 
message to this list does.  Can anyone figure out what the problem with 
exactly this mail is?  Alas, I cannot, at the moment.

Best wishes,
Wolfgang

Which puts in the headers that it came from a node in it's network,
which makes the machine the mail originated from, you guessed it, one
that has a dynamic IP address.

Your best bet would be to setup SMTP auth on your own server.

Okay, maybe not most of them.  I have attached a concrete message where this 
problem occurs.  Maybe that helps.

Thanks for help.
