    I have an internet server that uses I.P. address **************. Proofpoint has listed it as a spam generator so all its customers block our ********* server is regularly tested both by automated systems and by manual tests by personnel at the ********* service provider. There are no viruses or other exploits. Analysis of log messages show there has been no unusual email activity for the entire period of time that this server has been in operation, since November of 2024.Many of the people, organizations and companies that I communicate with regularly subscribe to Proofpoint. They feel that gives them better control of spam and unwanted email.But my experience with Proofpoint has been that they have only blocked legitimate communications attempts with no good reason.

    ** We have been delisted from ****************** and delisted from TalosIntelligence who took over senderbase. We do not spam, we do not host spammers and we have been in business since 1998. It is unfortunate that these groups are not as attentive to the removal as they are to the addition of these servers. This is affecting our business but more importantly the businesses of our clients. Many of our clients are BBB members. Thank you for your time.

    I am rejecting this response because: This issue has not been cleared and it has been 2 weeks now getting this IP address unblocked. It is making it incredibly difficult to email with one of our customers that we do a large portion of our business with. Here is what I got as a bounce back which has been the same thing for the last 2 weeks.

    We would like to request the removal of our email system from the blacklist.I made a lot of ticket but have not received any response from Proofpoint, and the situation remains unresolved.Having our email system listed on the blacklist has caused significant disruptions in communication with our customers and partners. This issue not only affects our daily operations but also results in information loss and damages the reputation of our business.We kindly request your support in resolving this matter as soon as possible to ensure that critical transactions and communications are not delayed. We look forward to receiving a response from your team at the earliest convenience.Thank you and we hope to collaborate with you soon!My ISP IP mail server is **************
