I have received an email from MAILER-DAEMON@mailchannels.net stating that my latest email to my nine fellow trustees of the charity has been rejected by just three recipients as "spam".:
host mx.avasin.plus.net[212.159.8.200]
said: 552 Spam Message Rejected (in reply to end of DATA command)
Hundreds of other similar emails concerned with the administration of the charity have been delivered to these addresses over the years without problem. I have no idea why this message has suddenly been classed as "spam". We are a small charity with about 150 members, run by 10 overworked trustees without any real expertise in IT.
Please could you let me know how do I remedy this situation?
