RESTAPI:Mails can not be sent with enabled SPF

Applies to:

All mail servers with enabled SPF

Symptom:

If SPF (Sender Policy Framework) is enabled on your mail server, mails cannot be sent via Cryptshare.

Cause:

As soon as SPF has been activated, mails will only be sent by mail servers that are explicitly enabled by the entry. If not, mails will be blocked. Because a mail sent via Cryptshare has several senders by default, the mail will be blocked.

Solution:

Disable the setting Allow using individual sender addresses

Log in to Cryptshare administrator menu:
# Navigate to System-Settings → Mail Server Settings
# Disable the box Allow using individual sender addresses
