Hello Zimbra Customers, Partners & Friends,
Zimbra’s Barry de Graaff and Randy Leiker from Skyway Networks team up for a new webinar series focused on Email Security. These hands-on webinars will include practical how-to information and best practices to help you maximize Zimbra.
Learn how to fine-tune key security standards like SPF, DKIM, DMARC, MTA-STS, TLS, DNSSEC, DANE and TLSA to create a nearly unbreakable chain of trust from email sender to email recipient, ensuring maximum integrity and confidentiality. The webinars will include best practices and how to avoid common roll-out pitfalls for each security standard.
This first webinar focuses on email security and using SPF and DKIM.
If you’re interested, here is the slide deck from the webinar.
Thanks,
Your Zimbra Team
Any chance you guys are planning to fix the Zimbra out-of-office replies that are missing DKIM headers?
Hello Toby,
Zimbra can already send out-of-office replies that are DMARC passing, even on strict settings. To make this work you need to make sure to pass either SPF or DKIM. Please check if zimbraAutoSubmittedNullReturnPath is set to false zimbraAutoSubmittedNullReturnPath:
