SCP-####

SCP-#### (Safe) is an otherwise-ordinary IBM Thinkpad running Windows 95 with a copy of Outlook 97 installed

the email client appears normal, but the Scheduled Send option in the Compose window will accept dates in the past

if the Send button is clicked with a past date entered, the email will be sent and arrive at that past date and time

messages are sent via a period-appropriate system and cannot be transmitted before the availability of commercial electronic communications in 1844

the general pattern of methods is as follows:

-1844-1933: telegraph

-1933-1971: teleprinter

-1971-1981: SNDMSG over Arpanet

-1981-present: SMTP

some messages are sent using prior methods, seemingly due to receiver availability
