Hi,

I found that your email address has had several bounced messages from our Cloud services recently.

554 5.7.1 Service unavailable; Client host [a.b.c.d] blocked using spamcop.dnsbl; Blocked - see https://www.spamcop.net/bl.shtml?a.b.c.d

But we are also seeing email bounce messages such as

421 4.4.0 [internal] no mail servers for this domain could be reached at this time

Which would tend to point towards your DNS MX records have a problem.  For example, checking https://mxtoolbox.com/emailhealth/engenhariahibrida.com.br/ would tend to indicate that your mail servers have been blocked by anti-spam services.

I would recommend that you reach out to your email administrator so that they can contact your mail provider to resolve this problem in the long term.

I have done what I can from our side to try to help, by removing your address from our suppression list.  But I fear that you will continue to have problems while your mail server is on that block list.

Hi @Projetos EngHibrida  - Welcome to the Atlassian Community!

It might be that the user's email address has been blacklisted by Atlassian for some reason. Let me see if someone from Atlassian can take a look.
