554 5.7.1

When sending email out of eudora on hughes internet service, all emails to both yahoo.com and gmail.com get bounced.

these are legit emails to family.

single, original emails, not forwards, not spam.

there is no outgoing signature, no attachments(service is SLIGHTLY faster than dialup)

this happens irregardless of address book or direct typing.

a bit of goggling and I see that hughesnet.com has an atrocious rating and is most likely blacklisted on those servers.

It is also possible and likely that hughes/eudora might be using TLSv old version instead of new.

Possible scenarios:

• The IP address has been included in a Real-Time Blacklist due to Spam coming from your domain.
• Your domain or IP address has been blacklisted by the recipient.

this site;

http://multirbl.valli.org/lookup/hughesnet.com.html

clearly shows huighesnet is blacklisted on 3 servers, failed on 1, listed on 1 other.

This assumes if theres 1 fault, there must be others.

and since neither gmail or yahoo are even available to be checked-they are probably blacklisting too.

 Testing other domainas yeilded zero fails.

says "No DMARC Protection" and all I know about that is goggle... but apparently hughes doesnt have the right settings.

Does IP Address comply with reverse hostname naming convention... Failed!

RATS-Dyna - On the list. Worst Offender Alert.

This is a Worst Offender Alert and this means that not only this IP address, but the whole class 'C' is also on the indicated SpamRats List. Usually this means the whole range has the same issue of naming conventions or no reverse DNS AND that many IP's from this Class C have been used in Spam Attacks, Dictionary attacks or other forms of attacks, as detected by Mail Servers in the Data Collection Grid. You will NOT be able to use the removal form to remove your IP Addresses. If you have recently been assigned the IP Addresses, or have changed what these IP Addresses are used for, you can use the contact form and ask for a reclassification, but you will have to provide full disclosure, including whois for the ip addresses, your affiliation with the company that owns them, and a description of what the IP's were previously used for, and what they will be used for, in order for a Spam Auditor to consider reclassification. Remember, the majority of the IP's in this space WERE detected as being involved in some form of attack or abusive behaviour, so you had better have a good reason to ask for removal, and you need to own or control the IP addresses, as evidenced by ARIN whois.

• We are sorry that we cannot remove your IP address at this time. This IP Address appears to be designated as a 'dynamic' IP Address.
• Only the ISP or company that has control over the IP Address may request a removal.
• Being listed on SpamRats should not affect you in any way, or your ability to send email through your email provider. If it does, and you get a bounce message, it is much more likely that this is a problem with your email client configuration.
• Please contact your ISP to address this issue.
