I have a postfix-mailserver, which works for incoming and outgoing mail. Everything was fine until I created a Mailchimp-Account. The Activation-Mail wasn't recieved by my postfix-Server. Several other activation-mails from Amazon/Paypal/... worked fine.
My mail.log:
Dec 20 10:17:30 *** postfix/smtpd[23774]: connect from systemalerts8.mailchimp.com[198.2.140.10]
Dec 20 10:17:30 *** postfix/smtpd[24052]: connect from systemalerts8.mailchimp.com[198.2.140.10]
