Unusual bounce increase

Hi Community,

 

Wonder if any of you encounter a higher bounce (both hard and soft) this month, such as double (5-6%) than in the previous months (2-3%)?

A couple of the bounce details for records that were not bounced in the past:

550 Unable to add --- because host ---- is listed on bl.spamcop.net

550 JunkMail rejected - ---.mktomail.com [---- is in an 550 RBL: Blocked - see http://www.spamcop.net/bl.shtml?---

550 spamcop.mimecast.org Blocked - see http://www.spamcop.net/bl.shtml?---

550 [internal] [oob] The response text could not be identified.

 

Is this related to Marketo's servers, or to the sender servers?

 

Thank you,

Emilia
