Hello I just started to use some IP addressess to send emails toward clients, but I received back a lot of emails referencing IronPort Poor Reputation.
From this email addressess we never sent any emails before and is really annoying that a lot of emails get rejecetd because of this. Our IP's are not listed in any blacklists.
Also our main mail server IP (91.201.80.3) is on the same IP class as this new servers but that server has a Neutral classification.
I already sent email's to support@senderbase.org without any answer.
The new IP's used to send emails are:
91.201.80.25
91.201.80.26
91.201.80.27 - not yet sending emails
91.201.80.28 - not yet sending emails
91.201.80.29 - not yet sending emails
91.201.80.30 - not yet sending emails
Just a side note, we are not sending any SPAM messages, all the DNS forward/reverse settings are correct, the SPF records are configured correctly, also we are signing any outgoing email with DKIM signature.
