SURVEY OF FTP MAIL AND
Two surveys of Arpanet Server hosts were run between September 20, 1978
and December 11, 1978. The intent was to determine the response of
host's Server FTP program to
(a) An attempt to mail to an unknown recipient at that host.
purpose of this survey was two-fold. First, to determine whether
host accepts mail for unknown recipients at all, and second,
response the host gives if it does not accept such mail
(b) An attempt to mail to a known recipient using the MLFL
rather than the usual MAIL command. This survey was undertaken
determine the extent of support for the MLFL command among Server hosts
and the sort of reply received if the Server does not support MLFL.
is potentially a 'better' form of communication than mail as the
is sent over a data connection rather than the command connection
Using the data connection eliminates the 'end-of-mail' marker
'command reader' problems sometimes encountered over the
connection
The ground rules of the survey were that all sites listed as Servers
the MIT/SAIL Host table were surveyed. In many cases, a host listed
a Server would not respond to an ICP at any time during the period
the survey. Once a host responded with what seemed to me to be
'definitive' answer, I marked it as such and stopped surveying it
MLFL
The algorithm used was to ICP to socket 3 of the server (the
old-FTP socket). Once a 300 response was received, I sent the
command. Where I had the name of a real mailbox at a site (
Header-person, for example) I used that, otherwise the name "**". If
site asked for a password (response 504) after the MLFL command I
"USER NETML" "PASS NETML" and retried the MLFL. If the server
with a 255 SOCK command, I listened for the data-connection to
established. When it was, I transferred the mail file.
enough, most sites implement an RFC queueing algorithm that will
the user site to attempt to establish the data-connection from its end

Sites are grouped by the general result they gave
-site- -last ftp reply if lost- -when
1) Sites that lost for various reasons
BNL 530 NOT LOGGED IN. after
HARV-10 431 INVALID ENTRY - Try again after

Note: "when" describes the last action performed by the surveyer
the indicated anomalous response
after ICP -- surveyer had done ICP to socket 3
after MLFL -- surveyer had sent MLFL
after USER -- surveyer had sent USER NETML in response
"504 Login please
after SOCK -- surveyer had attempted to connect to
data

Survey of FTP MAIL and
MAIL
The mechanics of the MAIL survey were similar to those of the
survey. The command was "MAIL Fzorkness" (an account unlikely to
on any host). The responses are grouped into a few general categories

if you see any problems within the linking, don't worry be happy,
this is version 0.1 of the Relevance System and you gotta expect some crappy subroutines sometimes,
just be content we did not write this in Java, which would have made this "bigger and better" HAHAHHA.
