Email Filters

ServieNowの System Mailbox - Filters にEmail Filtersというものがあり

Ignore Headerは受信したメールのヘッダーに特定の文字列が含まれるときに受信を拒否しているようで

Ignore Subjectは受信したメールのSubjectに特定の文字列が含まれるときに受信を拒否しているようです

先日見た他のインスタンスと自分のPDIで存在するFilterの種類と内容が違うような…バージョン違いかな…?

同じようにボディに特定の~でも受信拒否を設定することが出来るはずです

ServiceNowのインスタンスから送信されるメールには X-ServiceNowなんちゃらというヘッダが付いてFilterで受信拒否されるようです これはServiceNowインスタンスが自動配信するメールが複数のインスタンス内でループしてしまうことを防ぐ仕組みのようです

2024-04 DefaultのEmail Filterはドキュメントによると

以下のようです

Filter Descrioption
Ignore VCAL Ignores all email containing vCalendar requests. This filter prevents inbound email actions from creating unnecessary incident records when the instance receives a response to sent email. vCalendar requests in email responses are identified by the EmailUtils script include.
Ignore header Ignores email that contains specific headers. This filter overrides the glide.pop3.ignore_headers property.
Ignore sender Ignores email from specific senders. This filter overrides the glide.pop3.ignore_senders property. Tip: To ignore emails from untrusted domains and addresses, consider setting up a system address filter instead. For more information, see System address filters.
Ignore subject Ignores email with specific terms or phrases in the subject line. This filter overrides the glide.pop3.ignore_subjects property. This filter might not apply to emails arriving from unknown users. Unknown users can be locked out.
Move spam to junk folder Moves email identified as spam to the Junk folder. This filter checks for the value of the ServiceNow spam header. If the header is X-ServiceNow-Spam-Status:Yes, the filter moves the email to the Junk folder

自分のPDIにはIgnore snderが無いようです気にしないことにします
