(Main)Electronic Signatures and Infrastructures (ESI) - Registered Electronic Mail (REM) Services - Part 4: Interoperability profiles
Electronic Signatures and Infrastructures (ESI) - Registered Electronic Mail (REM) Services - Part 4: Interoperability profiles
The present document specifies the interoperability profiles of the Registered Electronic Mail (REM) messages
according to the formats defined in ETSI EN 319 532-3 [6] and the concepts and semantics defined in ETSI
EN 319 532-1 [4] and ETSI EN 319 532-2 [5]. It deals with issues relating to authentication, authenticity and integrity
of the information, with the purpose to address the achievement of interoperability across REM service providers,
implemented according to the aforementioned specifications.
The present document covers all the options to profile REM services for both styles of operation: S&N and S&F.
The mandatory requirements defined in the aforementioned referenced REM services specifications are not normally
repeated here, but, when necessary, the present document contains some references to them.
More specifically, the present document:
a) Defines generalities on profiling.
b) Defines constraints for SMTP profile.
The present document also specifies a REM baseline supporting the technical interoperability amongst service providers
in different regulatory frameworks.
NOTE: Specifically but not exclusively, REM baseline specified in the present document aims at supporting
implementations of interoperable REM services by use of Trusted List Frameworks to constitute Trusted
domains and qualified REM services (instances of electronic registered delivery services) by use of EU
Trusted List system as per Regulation (EU) No 910/2014 [i.1].
Elektronski podpisi in infrastruktura (ESI) - Storitve priporočene elektronske pošte (REM) - 4. del: Profili medobratovalnosti
Ta dokument določa profile medobratovalnosti za sporočila storitve priporočene elektronske pošte (REM) v skladu s formati, opredeljenimi v standardu ETSI EN 319 532-3 [6], ter s koncepti in semantičnimi vsebinami, opredeljenimi v standardih ETSI EN 319 532-1 [4] in ETSI EN 319 532-2 [5]. Obravnava zadeve v zvezi s preverjanjem pristnosti, verodostojnostjo in celovitostjo informacij z namenom zagotavljanja medobratovalnosti med ponudniki storitev priporočene elektronske pošte, ki se izvaja v skladu z zgoraj navedenimi specifikacijami.
Ta dokument zajema vse možnosti profiliranja storitev REM za oba načina obratovanja: S in N ter S in F.
Obvezne zahteve, opredeljene v zgoraj navedenih referenčnih specifikacijah storitev priporočene elektronske pošte, se na tem mestu običajno ne ponavljajo, vendar ta dokument vsebuje nekaj sklicev nanje, kjer je to potrebno.
Ta dokument natančneje določa:
a) splošnosti o profiliranju;
b) omejitve za profil SMTP.
Ta dokument določa tudi osnovna načela priporočene elektronske pošte, ki podpirajo tehnično medobratovalnost med ponudniki storitev v različnih regulativnih okvirjih.
OPOMBA: Namen osnovnih načel priporočene elektronske pošte, določenih v tem dokumentu, je med drugim zagotavljanje podpore za izvedbo medobratovalnih storitev priporočene elektronske pošte z uporabo okvirjev zanesljivih seznamov, ki predstavljajo zaupanja vredne domene in kvalificirane storitve priporočene elektronske pošte (primere storitev elektronske priporočene dostave), pri čemer se uporablja sistem zanesljivih seznamov EU, skladen z Uredbo (EU) št. 910/2014 [i.1].

Introduction
Registered Electronic Mail (REM) is a particular instance of An Electronic Registered Delivery Service (ERDS).
Standard email, used as a backbone, makes interoperability smooth and increases usability. At the same time, the
application of additional security mechanisms ensures integrity, confidentiality and non-repudiation (of submission,
consignment, handover, etc.). It protects against the risk of loss, theft, damage and any illegitimate modification.
The present document covers the common and worldwide-recognized requirements to address electronic registered
delivery securely and reliably. Particular attention is paid to the Regulation (EU) No 910/2014 [i.1]. However, the legal
effects are outside the scope of the present document.

Introduction
Registered Electronic Mail (REM) is a particular instance of An Electronic Registered Delivery Service (ERDS).
Standard email, used as a backbone, makes interoperability smooth and increases usability. At the same time, the
application of additional security mechanisms ensures integrity, confidentiality and non-repudiation (of submission,
consignment, handover, etc.). It protects against the risk of loss, theft, damage and any illegitimate modification.
The present document covers the common and worldwide-recognized requirements to address electronic registered
delivery securely and reliably. Particular attention is paid to the Regulation (EU) No 910/2014 [i.1]. However, the legal
effects are outside the scope of the present document.

1 Scope
The present document specifies the interoperability profiles of the Registered Electronic Mail (REM) messages
according to the formats defined in ETSI EN 319 532-3 [6] and the concepts and semantics defined in ETSI
EN 319 532-1 [4] and ETSI EN 319 532-2 [5]. It deals with issues relating to authentication, authenticity and integrity
of the information, with the purpose to address the achievement of interoperability across REM service providers,
implemented according to the aforementioned specifications.
The present document covers all the options to profile REM services for both styles of operation: S&N and S&F.
The mandatory requirements defined in the aforementioned referenced REM services specifications are not normally
repeated here, but, when necessary, the present document contains some references to them.
More specifically, the present document:
a) Defines generalities on profiling.
b) Defines constraints for SMTP profile.
The present document also specifies a REM baseline supporting the technical interoperability amongst service providers
in different regulatory frameworks.
NOTE: Specifically but not exclusively, REM baseline specified in the present document aims at supporting
implementations of interoperable REM services by use of Trusted List Frameworks to constitute Trusted
domains and qualified REM services (instances of electronic registered delivery services) by use of EU
Trusted List system as per Regulation (EU) No 910/2014 [i.1].

7 Draft ETSI EN 319 532-4 V1.1.7 (2022-01)
Introduction
Registered Electronic Mail (REM) is a particular instance of An Electronic Registered Delivery Service (ERDS).
Standard email, used as a backbone, makes interoperability smooth and increases usability. At the same time, the
application of additional security mechanisms ensures integrity, confidentiality and non-repudiation (of submission,
consignment, handover, etc.). It protects against the risk of loss, theft, damage and any illegitimate modification.
The present document covers the common and worldwide-recognized requirements to address electronic registered
delivery securely and reliably. Particular attention is paid to the Regulation (EU) No 910/2014 [i.1]. However, the legal
effects are outside the scope of the present document.

1 Scope
The present document specifies the interoperability profiles of the Registered Electronic Mail (REM) messages
according to the formats defined in ETSI EN 319 532-3 [6] and the concepts and semantics defined in ETSI
EN 319 532-1 [4] and ETSI EN 319 532-2 [5]. It deals with issues relating to authentication, authenticity and integrity
of the information, with the purpose to address the achievement of interoperability across REM service providers,
implemented according to the aforementioned specifications.
The present document covers all the options to profile REM services for both styles of operation: S&N and S&F.
The mandatory requirements defined in the aforementioned referenced REM services specifications are not normally
repeated here, but, when necessary, the present document contains some references to them.
More specifically, the present document:
a) Defines generalities on profiling.
b) Defines constraints for SMTP profile.
The present document also specifies a REM baseline supporting the technical interoperability amongst service providers
in different regulatory frameworks.
NOTE: Specifically but not exclusively, REM baseline specified in the present document aims at supporting
implementations of interoperable REM services by use of Trusted List Frameworks to constitute Trusted
domains and qualified REM services (instances of electronic registered delivery services) by use of EU
Trusted List system as per Regulation (EU) No 910/2014 [i.1].
