emails to group emails not going through for club 3972.

A few months ago, my ISP had an email outage and no emails could be sent or received.
Ever since then, when I send emails to the group emails (members, officers), the emails don't go through.  I do receive emails that other send thru the group emails.
I assume it is because my email was flagged as invalid during the outage.
How do I get my email address off of the naughty list so that I can use the group email lists?

We are not blocking your email server at IP129.159.88.32 for monivan@astound.net
Please provide the full email header with the error you are receiving

There is no error message.  The emails just don't get to anyone.
I'm not sure if this is why our new members are not getting their opt-in emails (which I asked about in a separate thread).

what is the email address you are sending to?
