Erroneous permanent email errors

I periodically get returned email with permanent errors.  These can be from a distribution list or to individuals.  The addresses on the distribution are from comcast, aol, gmail, snet, and hotmail.  The individual failure is most often from aol.  Most of the time, all the addresses work.  Once in a while, 5 or 6 kick back, not always the same ones.  However, I do not believe either the comcast nor hotmail addresses ever failed.  This is my personal email from home and is going to other personal email systems.  The errors occur when I am the originator as well as when I am replying to all.  When an error code is included in the delivery failure notice, it is usually 554 5.7.9, once in a while it is 550 5.7.26.  The text of the message always refers to a permanent error.  But the next time I send, it goes through so it is not permanent.  This has been going on since at least April when I started recording it.  

Please help!

I use Apple Mail on my iPad for most mail.  Each of my accounts is set up to use the corresponding smtp server.  BUT, Apple Mail has an option to use a different smtp server if Mail is unsuccessful using the initial server.  For aol and gmail, I have the option set on.  Aol can use comcast.smtp.net as the backup.  Is that the source of the issue?  It still only happens quite sporadically.  I’m thinking there may be a failure from aol with smtp.aol.com and it tries again with comcast and hits a policy error.  I will change the settings so there is no backup and see what happens.

@user_093255 

We need the full error message that you're getting, not just the numbers.

Googling 554 5.7.9 gives this return.

Googling 550 5.7.26 gives this return.

So now you know why we need the exact full error message.

Here are 3 examples with transcripts.  All of these addresses work most of the time.  Example 1 was sent to one individual.  2 and 3 were to the distribution list or reply to same list.  Let me know if you need anything else.  I’m particularly curious about why this is so erratic.  Thanks!

Also see the 550 and 554 error codes on https://postmaster.comcast.net/smtp-error-codes.php#452.

Good afternoon,

Please do also note that the errors you receive do give you a direct link to view the errors:
<<< 554 5.7.9 Message not accepted for policy reasons. See https://postmaster.yahooinc.com/error-codes

NOTE: policy reasons

The message contains characteristics that Yahoo won't accept for policy reasons.

This indicates that yahoo has specifically blocked your messages due to their own internal reasons. You will want to find out from Yahoo exactly why.


EDIT: after further review it appears to be a DMARC issue in relation to policy. I highly recommend not using comcast smpt to send emails as aol.com

... The text of the message always refers to a permanent error.  But the next time I send, it goes through so it is not permanent. ...

"Permanent" in this context only refers to that particular email. It just means the mail system has determined that it cannot do anything more with the message. Later emails may be accepted if the condition that caused the failure has been corrected.

Thank you, BruceW and XfinityCSAEmail.  I’m beginning to get it.  It looks like my email is rejected due to a perceived policy violation which I assume is the DMARC issue and the issue is not detected the next time I send.  I see that aol.com uses DMARC, Comcast.net does not but xfinity.com does.  You suggested not using comcast smtp to send mail from an aol account.  My internet provider is comcast. Is there another way to do it that avoids this problem?  Is there a way to send from aol, gmail and comcast email accounts via xfinity.com?  What do I do next to avoid get email rejected?  

Thanks!

Good morning,

To clarify a bit further - majority of email services have DMARC, including comcast.net. More details about DMARC can be found here: https://dmarc.org/

The issue is more specific to how you're using comcast, aol, and gmail. How are you exactly using all 3 email accounts that you own? In a hopefully simpler explanation, you are sending emails as smtp.comcast.net through your aol.com account and AOL policy basically blocks it because its not coming from smtp.aol.com. To note, just because you have Comcast internet does not automatically mean you are using smtp.comcast.net - its the settings you have to configure to use smtp.comcast.net regardless of how you get your internet. If they were allowing email delivery from smtp.comcast.net would mean they would allow authentication from any smtp.anyemail.com/org/net - meaning that their smtp email authentication could potentially be used for abusive activity. Alternatively, it would look like emails are coming from aol on the receiving side, but actually they are coming from wherever should aol allow it(which they don't and is what you're experiencing as a policy block).

Overall, Its the setting of however you are accessing your other emails besides comcast.net. You want to make sure that your smtp settings are configured correctly per individual server. Essentially aol you go through their smtp authentication, gmail you go through gmail smtp authentication.
