This is what an RFC822 address looks like in a certificate:

  rfc822Name     IA5String

This is what an X.400 address looks like  in a certificate:

	ITU-Braindamge ::= SEQUENCE {
		built-in-standard-attributes		SEQUENCE {
			country-name  [ APPLICATION 1 ]	CHOICE {
				x121-dcc-code				NumericString,
				iso-3166-alpha2-code		PrintableString
				},
			administration-domain-name
						  [ APPLICATION 2 ]	CHOICE {
				numeric						NumericString,
				printable					PrintableString
				},
			network-address			  [ 0 ]	NumericString OPTIONAL,
			terminal-identifier		  [ 1 ]	PrintableString OPTIONAL,
			private-domain-name		  [ 2 ]	CHOICE {
				numeric						NumericString,
				printable					PrintableString
				} OPTIONAL,
			organization-name		  [ 3 ]	PrintableString OPTIONAL,
			numeric-use-identifier	  [ 4 ]	NumericString OPTIONAL,
			personal-name			  [ 5 ]	SET {
				surname				  [ 0 ]	PrintableString,
				given-name			  [ 1 ]	PrintableString,
				initials			  [ 2 ]	PrintableString,
				generation-qualifier  [ 3 ]	PrintableString
				} OPTIONAL,
			organizational-unit-name  [ 6 ]	PrintableString OPTIONAL,
			}
		built-in-domain-defined-attributes	SEQUENCE OF {
			type							PrintableString SIZE(1..64),
			value							PrintableString SIZE(1..64)
			} OPTIONAL
		extensionAttributes					SET OF SEQUENCE {
			extension-attribute-type  [ 0 ]	INTEGER,
			extension-attribute-value [ 1 ]	ANY DEFINED BY extension-attribute-type
			} OPTIONAL
		}

Given that, I would hope that X.400 not only includes a recipient deceased
non-delivery notification but also a detailed record of what the cause of
death was, a complete autopsy report, and an address to send flowers to.
