Hello,
the mailbox from the subject got hacked and has been used for massive spamming.
We have changed the password, because the hacker/spammer has the right login-data for the mailbox.
On one or more PC’s, where this mailbox is/was active, is probably a trojan or something similar installed and spied out the password and username.
If the PC or similar has been cleaned and checked a new password can be set in the Server-Interface.
Please confirm this message.
Best regards.
