Spamer ? (for literal router:you are not permittermitted...)

can anyone please tell me what error is this:
probably this is a spamer problem...
What is "literal"? looking on server i found a doc. "imapproxy_literal_dos.nasl" with inside the following:
-------
C^@^@^@í=^@^@d2bef1e0a1405bed8391d8af39579bfa^@/usr/local/lib/nessus/lugins/imapproxy_literal_dos.nasl^@^@^@^@^@^@^@^@^@^@^$
The remote host is running at least one instance of up-imapproxy that does
not properly handle IMAP literals. This flaw allows a remote attacker
to crash the proxy, killing existing connections as well as preventing
new ones, by using literals at unexpected times.

Solution : Upgrade to up-imapproxy 1.2.3rc2 or later.
Risk factor : Low^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^$

the errors i see are:
