Detailed Description

Macro Definition Documentation

#define MAXRCPT   500

maximum number of recipients in a single mail

Function Documentation

int http_post

(

void

)

http_post - handle HTTP POST request

This has nothing to do with SMTP at all. But I have seen many proxy attempts trying to send spam and beginning the connection with a sequence like this:

POST / HTTP/1.0 Via: 1.0 SERVEUR Host: mail.sf-mail.de:25 Content-Length: 1255 Content-Type: text/plain Connection: Keep-Alive

RSET

This function is only there to handle this connections and drop them as early as possible to save our traffic.

Variable Documentation

unsigned int rcptcount

number of recipients in lists including rejected

char* rcpthosts

memory mapping of control/rcpthosts

off_t rcpthsize

sizeof("control/rcpthosts")
