Good day i have started to recieve this bounce message in communications with my aliases, even though we had already a long conversation before, all extra e-mails are bouncing back form my e-mail addres
Delivery to the following recipient failed permanently:
mgeorgievskaya[at]moscowpost.ru
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain moscowpost.ru by mx02.moscowpost.ru. [212.100.129.21].
The error that the other server returned was:
550 5.7.1 Message rejected due to content restrictions
I'm wondering if it is possible to find out how and why it was blocked, you as a powerfull organisation can help me to resolve this issue?
I'm sure that massages i was sending had no attachments or mailware nor fishing links, just plain text.
e-mail i'm using is info[at]yaminyami.com
