SpamCop is Blocking Emails from my Securities Platform, NinjaTrader

[DayByDay]

According to the block report from my email hosting provider, SpamCop is blocking emails from my brokerage securities platform, NinjaTrader.  How do I get SpamCop to allow those emails through?

Here's a copy of the report from the latest email that was blocked earlier today:

mailgun reject spam reports, they allow spammers to use their email server you are using, or you have a dirty email list.

You perhaps need to learn about double opt-in to create a clean email list.

Looks like when I follow the links to https://www.spamcop.net/w3m?action=blcheck&ip=143.55.232.12, it says email has been sent to spam traps.  Either that IP is being shared with a spammer or else your list is not double-opt-in.  Double Opt-In means I would not be able to add any email address in retaliation, but that an email is sent to the address to with the link to be added.

 

143.55.232.12 listed in bl.spamcop.net (127.0.0.2)

If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 7 hours.

Causes of listing

• System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)
• SpamCop users have reported system as a source of spam less than 10 times in the past week

Looking at the reported email, subject, some may be from financial services, but Mailgun have the 90 day 5,000 emails a month free trial and a lot of subject refers to being of Chinese origin.
Mail gun not accepting SpamCop abuse reports seems stupid?
Again "Free" accounts IMO need at least a $1 credit-card charge would hinder spammers give them the $1 back if they wish to continue.
Would stop bots multiple sign-up

This was/is the reason for the blocking list.  When folks stopped accepting reports, they would be unable to send email.  (Meaning, deal with the reported spam issues....)
