Turn off the attempts to notify the "biff" service.
Return a permanent error instead of a temporary error if a mailbox exceeds quota.
Specify this is a delivery (for backward compatibility). This option has no effect.
Specify the name of the mailbox database which is used to look up local recipient names. This option defaults to "pw", which means use getpwnam().
Specify the senders name.
Turn on LMTP mode.
Turn off the fsync(2) call that forces the mailbox to be committed to disk before returning a "success" status.
Specify the senders name (for backward compatibility). Same as -f.
Store incoming mail in filename in the users home directory instead of a system mail spool directory.
The next options are only available if mail.local has been compiled with -DHASHSPOOL.
Select hashed mail directories. Valid hash types are u for user name and m for MD5 (requires compilation with -DHASHSPOOLMD5). Example: -H" u2" selects user name hashing with a hash depth of 2. Note: there must be no space between the hash type and the depth.
Specify an alternate mail spool path.
Specify that the domain part of recipient addresses in LMTP mode should not be stripped.
Individual mail messages in the mailbox are delimited by an empty line followed by a line beginning with the string From . A line containing the string From , the senders name and a time stamp is prepended to each delivered mail message. A blank line is appended to each message. A greater-than character (>) is prepended to any line in the message which could be mistaken for a From delimiter line (that is, a line beginning with the five characters From following a blank line).
The mail files are exclusively locked with flock(2) while mail is appended, and a user.lock file also is created while the mailbox is locked for compatibility with older MUAs.
If the biff service is returned by getservbyname(3), the biff server is notified of delivered mail.
The mail.local utility exits 0 on success, and >0 if an error occurs.
