We are having an issue where some emails that are sent are getting a bounce back with several different errors. Two of those include
"Your access to this mail system has been rejected due to the sending MTA's poor reputation", and
"temporarily deferred due to user complaints"
I have verified on MXtoolbox that we are not blacklisted. We did have two blacklists but I have already removed us from these lists so as of right now we are not listed on any blacklists, however emails are still not going through.
Inside smartermail I see under the admin management >spool > a list of the number of emails sent per user/ip and number of emails received per user/ip. The server ip looks like it has sent almost 10,000 emails in the last 24 hours. However, if I add how many emails each user has sent in the last 24 hours its only about 600 or so. The numbers dont add up and I am not sure if I am on a wild goose chase or if I am near the problem.
On a side note, I have limited experience with smarter mail but one of our clients uses it. Any help is appreciated!
