Bug#441465: exim4-config: CHECK_RCPT_REMOTE_LOCALPARTS is not RFC 2822 compliant

[Keith Kennedy]

Package: exim4-config
Version: 4.63-17
Severity: normal


The variables CHECK_RCPT_REMOTE_LOCALPARTS and
CHECK_RCPT_LOCAL_LOCALPARTS have a specification that is not entirely
RFC 2822 compliant.

They prohibit the use of meta characters such as '&%#' in the email 
address which is correct but does not allow them to be included when
the local part is quoted. For example:

	tom&jerry at debian.org <- not RFC 2822 compliant
	"tom&jerry"@debian.org <- is RFC 2822 compliant

The included regular expression blocks both.
