Is sendmail command available for 12.1 protocol version? According to me it is available for 14.0+ version. So i am wondering is there any other alternate command for the same?
According to the documentation, it is available.
"For protocol versions 2.5, 12.0, and 12.1, the body of the SendMail request is the MIME representation of the message to be sent. In this case, the client sets the Content-Type header to "message/rfc822"."

I'm trying to create a table in the migration file database, but I'm getting the error above, I've researched it, but I haven't been able to get a meaningful opinion.Can anyone answer the question who knows the answer?
I have written a simple "Get" request in Delphi7 using the Indy10 TIdSNMP component but it returns an empty reply.
The target device's Agent doesn't support v1 SNMP so I have configured it for SNMP version 2c.
I know that the OID I am requestin is correct as I used a MIB Browser to obtain it from the same device using its MIB.
I vaguely recall seeing a comment on the forums that Indy 9 only supported SNMP version 1, so I am wondering that's still the case for Indy 10?
At this time, Indy 10 still does not support SNMP versions above v1. It is on the TODO list:
#56: Update TIdSNMP to support newer SNMP versions

As of a few days ago it stopped working, right after security update 2017-0001.

I saw SOCKS protocol have the version 4 and version 5, which can be referenced from:
https://www.rfc-editor.org/rfc/rfc1928
http://www.openssh.com/txt/socks4.protocol
My question is:
Does SOCKS exist version 1 , version 2 or version 3 prior to version 4(SOCKS4)?
Yes, there were earlier versions of SOCKS prior to version 4, as evident by the following comment in the SOCKS v4 protocol spec:
http://ftp.icm.edu.pl/packages/socks/socks4/SOCKS4.protocol
SOCKS was originally developed by David Koblas and subsequently modified
and extended by me to its current running version -- version 4.
This is also mentioned in QNX's SOCKS reference:
http://www.qnx.com/developers/docs/6.5.0/topic/com.qnx.doc.neutrino_lib_ref/socksappendix.html
The original SOCKS was written by David Koblas (koblas#netcom.com). The SOCKS protocol has changed over time. The client library shipped as of printing corresponds to SOCKS v4.2. Since the server and the clients must use the same SOCKS protocol, this library doesn't work with servers of previous releases; clients compiled with these libraries won't work with older servers.
And no, you don't need to bother worrying about those earlier versions, as nobody actually uses them anymore. SOCKS4 is the minimum version still in use, though SOCKS4A and SOCKS5 are preferred.
Can I configure trap/notification targets by setting some OID values by sending SNMP SetRequest PDU's ?
If the agent implements it, the standard mechanisms are provided by SNMP-TARGET-MIB (RFC 3413), SNMP-NOTIFICATION-MIB (also RFC 3413), and (if SNMPv1 or SNMPv2c) SNMP-COMMUNITY-MIB (RFC 3584).
