"deny" using an ACL which reads $message_body_size. http://www.exim.org/exim-html-current/doc/html/spec_html/ch40.html http://www.exim.org/exim-html-current/doc/html/spec_html/ch11.html#SECTexpvar You might also like to use a router which redirects to :fail: with an appropriate message. > 2). Special Characters are not allowed in message_body i.e. `,#,+,& > I created one ACL but it isn't working i.e. > > deny message = Restricted characters in the message body > domains = +relay_to_domains > condition = ${if match{${lc:$message_body}} \ > {\N( \`|\#|\+|\&)$\N} \ > {yes}{no}} Firstly, I suggest you negate that - have the condition check that the body only contains allowable characters. Secondly, your condition will be more readable if you use [...] in the regex instead of (...|...|...). For example, something based on: ${if match{$message_body}{\N\A[A-Za-z0-9 ,.-]\z\N} ...} but you'll probably want to allow more characters than that, and maybe you'll also want to automatically fold NL/CR/TAB to spaces. In which case, look for "${sg" in the documentation. > 3). Sender's local_part should not exceed 10 characters. And, let me guess, should contain only 0-9 ? Add something like "local_parts = \N^[0-9]{1,10}$\N" to your router. All untested. Testing, and fixing my errors, I leave as an exercise for you. -- Dave Evans http://djce.org.uk/ http://djce.org.uk/pgpkey
