Hello,
For a couple of days now I have been unable to send emails containing Box links to many of my contacts. Specifically this relates to @bbc.co.uk addresses. As soon as I include any Box link the emails bounce, if I send them without it seems fine.
The error messages include:
553-Message filtered
#5.7.1
What is going on?
Has Box been black-listed? Have I been black-listed?
Please help!
PS: I believe I have this problem with @hotmail.com & @outlook.com addresses too)
Hi Ilka,
Welcome to the Box Community, I'm happy to help!
I've checked the error you shared, and it sounds like your email with Box links is being blocked by Recipient Mail Server. I found this third-party forum discussing this same scenario that happens to you and thought it might help.
It sounds like you need to reach out to the recipient of your emails and ask that emails from the Box domains be added to their email allowlist (safe sender) to ensure that Box messages are not blocked. To see the details of these domains, please take a look at this article: https://support.box.com/hc/en-us/articles/360043696174-Troubleshooting-Issues-with-Email-Notifications
Thanks for reaching out and let us know how else we can help!
