Hi,I've noticed that I've started to receive lots of "Mail delivery failed: returning message to sender" messages. All of them coming from email addresses I dont even recognize. One typical gmail.com message starts with:
host gmail-smtp-in.l.google.com [64.233.180.26]
SMTP error from remote mail server after end of data:
550-5.7.1 [199.217.112.118 12] Our system has detected that this message is
550-5.7.1 likely unsolicited mail. To reduce the amount of spam sent to Gmail,
550-5.7.1 this message has been blocked. Please visit "
What should I do?
