Gmail doesn't authenticate messages signed with keys that use fewer than 1024 bits. Publish aSPF Record. Publish aDMARC policy. Re: 554 5.7.1 This IP has been flagged because it isdynamicor by suspect to be domestic use only. If you are running an email service on this IP, ask ISP to change therDNS. The removal of this IP from this blacklist depends on change ofrDNSto match the FQDN of the mail server. Re: 554 5.7.1 and of course-the emails attempted are full legit emails. also-when sending to teh yahoo, it said -failed to login and wouldnt send. successfull sends to other domains before, during, and after other fails.

It is also possible and likely that hughes/eudora might be using TLSv old version instead of new. https://knowledge.broadcom.com/external/article/155061/smtp-code-554-571-and-the-message-is-rej.html 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. this site https://mxtoolbox.com/problem/mx/dmarc-policy-not-enabled?page=prob_mx&action=mx:hughesnet.com&showlogin=1&hidepitch=0&hidetoc=1 says "No DMARC Protection" and all I know about that is goggle... but apparently hughes doesnt have the right settings. https://mxtoolbox.com/SuperTool.aspx?action=mx%3ahughesnet.com&run=toolpage when I check the ip; https://www.spamrats.com/lookup.php?ip=******** Does IP Address comply with reverse hostname naming convention...Failed! RATS-Dyna- On the list. Worst Offender Alert. This is a Worst Offender Alertand 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. this is from a computer of a virus free 80 year old lady(mom) Solved
