Assumpte: [Exim] smtp_max_unrecognized patch for 4.12
Hello,

I noticed the smtp_accept_max_nonmail setting in Exim 4.12. Here is my
trivial patch for unrecognized commands for Exim 4.12. I recommend
a lower default value, e.g. 3.

I looked at the quote_ldap_dn function. It uses backslashs for quoting,
but I can not find the relation to RFC 1485 (A String Representation of
Distinguished Names). Is that RFC outdated?

Michael
