Hello,
since 3 days i can`t send or recieve emails from *@web.de or *@gmx.de ( its a german company 1&1) with my xxx@skynet.be account. I try different email-clients and try it also directly on the webmailer on proximus.be. From my other email account (*@hotmail *@gmail) it work to send/recieved. The proximus phone support says it work all fine with skynet email…
I recieved every time after sending an email an other mail from Mail Delivery System:
---------- Original Message ----------
From: Mail Delivery System < MAILER-DAEMON@secure-mail.be>
To: ***@skynet.be
Date: 01 June 2020 at 16:04
Subject: Delivery Status Notification (Failure)
The following message to < ***@web.de> was undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 550-'Requested action not taken: mailbox unavailable\ninvalid DNS MX or A/AAAA resource record'
I try different @web.de/@gmx.de adresses with my skynet.be account, without success.
Because the @web.de adresses work for all other accounts, only skynet dosen`t, I believe the problem has to be on proximus side. Does someone know where i can send them a email? only thing i found is the phone support and there is no one who can help. Thank you
Kind regarts,
Dmitrij
