Overview: Difference Between fml4 and fml8

Anyone Can Post

Users registered as members can post ML by default. This default behaviour is common between fml4 and fml8. To set "anyone can post", in the case of fml4,

$PERMIT_POST_FROM = "anyone";

article_post_restrictions = reject_system_special_accounts
                            permit_anyone
                            reject

Subject Tag

No subject tag defined by default. This is common between fml4 and fml8 To set the tag such as '[ML_NAME:00100]', in the case of fml4,

$SUBJECT_TAG_TYPE = '[:]';

article_header_rewrite_rules = rewrite_article_subject_tag

article_subject_tag           = [$ml_name:%05d]

Disable Specific Command In Command Mail

Commands such as "members" are prohibited in fml8 by default. fml4 needs the following configurations to disable dangerous commands:

&DENY_PROCEDURE('member');
&DENY_PROCEDURE('active');
&DENY_PROCEDURE('members');
&DENY_PROCEDURE('actives');
&DENY_PROCEDURE('status');
&DENY_PROCEDURE('stat');

Old fml4 use no filter by default but fml8 uses filter by default.

fml8 applies confirmation for subscribe, chaddr, unsubscribe commands by default. fml4 not. Currently fml8 always applies confirmation, which can not be disabled by configuration.
