Hi everyone!
I want to manage mail server resource part (like it can CGP) and with it I have one question. Is any way to limit overall max simultaneous connections to imap/pop3 server from one(each) host, except use iptables/ipfw and so on? Like a patch to dovecot or, maybe, it can be released in future versions?
Probably in future versions.
I know about mail_max_userip_connections in dovecot 1.1
It should be pretty easy to patch this code to ignore the user and just limit IPs. You could basically just remove "user" from struct mail_process_group and fix the code to compile. Or even easier:
static struct mail_process_group * mail_process_group_lookup(enum process_type type, const char *user, const struct ip_addr *ip) { user = ""; // use the same empty user for everyone
// ...
static struct mail_process_group * mail_process_group_create(enum process_type type, const char *user, const struct ip_addr *ip) { struct mail_process_group *group;
user = ""; // use the same empty user for everyone
