mail-not-delivered

Sorry to bother you again with this subject but again, I find very strange that I’m receiving so many « Undelivered Mail Returned to Sender”

Messages since Tuesday (Nov 12th) in total there’s been 11 emails returned in only two days.



Some addresses I could believe they are fake but some others appear to be reliable.



Since ever, I receive this type of messages when sending emails from my normal email account jvl@joesnyder.com

But this is the first time that it’s being so regular in the last couple of days and I just want to make sure is not the server of

O2switch that has an issue and doesn’t allow customers to subscribe to the newsletter.



Or is it a kind of SPAM that is used to target some websites?



Or does it has to do with the configuration of Mailchimp?



Please let me know.



Thanks,



José
