Delivering e-mails to verdigado.net mail servers

To avoid mail delivery problems to our mail servers, please make sure that

• all used IP addresses have a reverse DNS PTR record.
• your servers wait at least 3 minutes for a second delivery attempt in case the mail is temporarily deferred.
• From and Envelope From headers in sent mails are aligned.
• SPF, DKIM and DMARC are working correctly.
• your servers support TLSv1.2 or TLSv1.3.
• improve your spam rating by signing your mails with PGP or S/Mime.

• We only send e-mails to mail servers that support TLSv1.2 or TLSv1.3.
• We enforce DMARC sender alignment for all outgoing e-mails from our system and managed customer domains. We encourage other e-mail providers to fully support DKIM, SPF and DMARC.
• We support MTA-STS.
