Mailfromd version 4.4 is available for download from ftp://download.gnu.org.ua/pub/release/mailfromd.

New in this release:

• The --domain option is withdrawn.

This option was declared as deprecated in version 4.0. Now it is withdrawn and its short version (-D) is reused for another purpose (see -D option, below).

• New command line options -D and -U

Both options work like their m4 counterparts: the `-D' command line option defines a preprocessor symbol, the `-U' option undefines it.

• Constant vs. variable shadowing

In previous versions of mailfromd name clashes between constants and variables went unnoticed, which sometimes lead to hard-to-diagnose errors. This bug is fixed in this version. If a constant is defined which has the same name as a previously defined variable (the constant "shadows" the variable), the compiler prints the following diagnostic message:

<file>:<line>: Warning: Constant name `name' clashes with a variable name
<file>:<line>: Warning: This is the location of the previous definition

A similar diagnostics is issued if a variable is defined whose name coincides with a previously defined constant (the variable "shadows" the constant).

In any case, the %NAME notation refers to the last defined symbol, be it variable or constant.

If a variable shadows a constant, the scope of the shadowing depends on the storage class of the variable. For automatic variables and function parameters, it ends with the final `done' closing the function. For global variables, it lasts up to the end of input.

• Exception names.

To minimize chances of name clashes, all symbolic exception codes has been renamed by prefixing them with the `e_', thus, e.g. `divzero' became `e_divzero', etc. The `ioerr' exception code is renamed to `e_io'.

For consistency, the following most often used codes are available without the `e_' previx: success, not_found, failure, temp_failure.

The use of old exception codes is still possible by defining a preprocessor symbol OLD_EXCEPTION_CODES, for example:

mailfromd -DOLD_EXCEPTION_CODES

• match_dnsbl and match_rhsbl

Both functions malfunctioned in versions from 4.0 up to 4.3.1 due to a name clash between the exception code `range' and their third argument. This is fixed.

Additionally, previous versions of match_dnsbl silently ignored invalid first argument. Now, the e_invip exception is signalled in this case.
