Toastmastersclubs.org Blacklisted?

Some of our users, who have Optonline.net email addresses, are no longer receiving the group emails using the officer or member distribution lists that use the toastmastersclubs.org SMTP addresses. I checked with Optonline tech support and they referred me to several blacklisted websites. I can see that using mxtoolbox.com and dnsstuff.com that there are some issues that need to be addressed for the toastmastersclubs.org domain. Can someone look into this and let me know.

Also, this issue started sometime in January.

Thank You.

The chile black list is run for mail servers in chile.

The issue with optonline.net that some of optonline.net have been labeled as spammers. I need to know exactly who is not able to receive mail and who is not able to send mail to the server.

Any mail bounce messages would be very helpful.

we are delivering email to optonline.net and it is being accepted, what optonline.net does with it after we do not know. As you see below all your active members have received email this week and it was accepted by oponline.net

I spoke with optonline tech support, and they told me there is a mailbox setting that can be modified, but before I make any changes can you try to send an email to my optonline account, cwardrop@optonline.net?

Let me know when you send it. If it fails, I'll make the change and have you resend.

Let me know.

You will have to make that your club email address and then send an email from the club to it. Do not send an email from cwardrop@optonline.net and expect it to be sent back to you.

I wasn't going to send an email from cwardrop@optonline.net.

I will test with an existing club member who has their optonline.net as the club email address and let you know.
