Thanks for the report. We’ll be looking into it.

According to:

550 spam detected

You receive this refusal message when one mail was detected as a spam by our antispam filter and the delivery was rejected. The non delivery report has been sent by the SMTP server you have used or, if you did not send this mail, by the SMTP server who have relayed a mail spoofing your email.

If you did send the mail, you should at first check your mail to make sure it should not be missdetected as a spam, either by using an antispam softwate or by checking if the mail is syntaxically correct and if you do not use any mecanism that are known to be used by spammers.
Failing that, you may send us a sample of rejected emails by following these instructions.

It could be something wrong with your email client you use, the content of the email or something that triggers the spam checker on the side of We need to check whether it is triggered for all the emails sent from our server or just your particular case. Let’s continue investigating and troubleshooting via our internal ticketing system. Please send email to and if possible (to speed up the process) please add headers of the email you are trying to send, username of your brother too so we can easier troublleshoot by examining logs.

Also is there a way to obtain email account from so we could better check things on both sides?

i tried to check the ip adress and it’s ok for free
i used smtp port 587 to send an email
i’ve got the same result with the webmail, directly from firefox
