#12896 assigned Bug/Something is broken

Delivery Status Notification Failure

Reported by: https://id.mayfirst.org/indiakushner Owned by:
Priority: Urgent Component: Tech
Keywords: gmail alias email Cc: roger@…
Sensitive: no

Description

I contacted your support team but haven't heard back. A team member has an alias set upon Gmail using your server. However, she recently started getting this message:

"Message not delivered: You're sending this from a different address or alias using the 'Send mail as' feature. The settings for your 'Send mail as' account are misconfigured or out of date. Check those settings and try resending."

She tried deleting her alias and readding it, then fixed the SMPT. It seemed like it was working but now she's getting the same message. We aren't sure if it's a Mayfirst issue or Gmail issue. Please respond ASAP.

Hi, I responded to your message in ticket #12889. I think you may have not seen my reply. Based on the error message in the screenshot you posted I asked whether the person sending was attempting to send an attachment. Is this by chance happening when they attempt to send large attachments or is it happening for messages without attachments a well?

Hi, I didn't see the message. It must have got lost in my email somewhere. From my colleague, the issue arises when they respond* to an email with their NationalCOSH.org account and try to include an attachment. Any way to resolve this?

Yes I believe the issue you had was the size of the attachment exceeded our server's limits. For very large files, I would suggest first uploading the file to our owncloud service https://share.mayfirst.org , you can use your May First user and password to access, once you've uploaded a file you can use the option to share that file with a link and copy that in your e-mail.

Thank you. I will let you know if we have further issues with it.

HI, my colleague is now having issues with no attachment at all. It's the same message:

Message not delivered You're sending this from a different address or alias using the 'Send mail as' feature. The settings for your 'Send mail as' account are misconfigured or out of date. Check those settings and try resending.

Any suggestions?

Just scanning the logs for anything related to your domain I do see some messages from gmail about blocked e-mails.

host gmail-smtp-in.l.google.com[173.194.204.26] said: 421-4.7.0 This message does not have authentication information or fails to pass 421-4.7.0 authentication checks. To best protect our users from spam, the 421-4.7.0 message has been blocked. Please visit 421-4.7.0  https://support.google.com/mail/answer/81126#authentication for more 421 4.7.0 information. w9si14997398qta.296 - gsmtp (in reply to end of DATA command)

From what I can tell this is happening when any of you use gmail as your e-mail client to send mail as a nationalcosh.org address to several other nationalcosh.org addresses that have been configured to be forwarded back to gmail again. Essentially you are just using mayfirst servers as an intermediary in these cases and gmail has implemented stricter controls that think your messages might be spam because of the way they are being forwarded.

Still, the above messages I see in the logs do not exactly match the error you posted above so I'm not certain it is the same problem you mentioned above. Also the problem I'm describing should be affecting more than one of your users. To solve this I think we should try and set an SPF record for your domain to tell other servers that the May First servers are authorized to deliver mail on behalf of your domain. You can see more info here:

https://support.mayfirst.org/wiki/faq/email/add-spf-record

I can help you get that setup if you like. The only caveat is that everyone using the nationalcosh.org domain will need to make sure they've configured their mail clients to use the mail.mayfirst.org smtp server.
