Topic: Trying To Send from MailChimp
Trying to send mail from mailchimp.com to recipients on iredmail server with the following error from mailchimp in the bounced email response:
500 No SMTP Service
I've added all their posted IP addresses to the whitelist and still nothing. I have the latest version of Iredmail. Any ideas?
