Problems with quoted email addresses.
If incoming mail is addressed to <" username"@localdomain.net>,
and username (without the leading space) is a valid ID, the
message passes through and ends up in a file
called '/var/mail/ username'.
It ends up that we have about 10-15 files in our /var/mail
that all begin with space characters. Any quick ideas on how
to prevent this?
With the quotes, <" username"@localdomain.net> should not be
a valid mailbox.
example follows. I'm running a very stock version of .cf files.
Also note the errors after the RCPT TO: line in the example.
/var/mail> telnet localhost smtp
Connected to localhost.
Escape character is '^]'.
