Expiration Notice Email Module

[auspex0]

Is it possible to create a module that we could load to send an email to the email address registered with a nickname, informing them when their account is due to expire in X days (e.g., 10 days before expiration)? The email would remind them to log in with their nickname and password to prevent the account from expiring.

i wonder, would something like this work:

/*

• This file contains code for the NickServ due to expire function.
  */

#include <atheme.h>

static unsigned int ratelimit_count = 0;
static time_t ratelimit_firsttime = 0;

static void send_expiration_email(struct myuser *mu);
static void check_nickname_expiration(void);

void send_expiration_email(struct myuser *mu) {
char *key = random_string(16);

const char *email_content = _("Dear %s,\n\n"
                              "Your nickname \2%s\2 is set to expire in 10 days. "
                              "Please make sure to log in and verify your account to avoid losing your nickname.\n\n"
                              "Thank you,\n"
                              "The Team")
                              % mu->name % entity(mu)->name;

if (!sendemail(NULL, mu, EMAIL_REGISTER, mu->email, key, email_content)) {
    slog(LG_INFO, "Failed to send expiration email to \2%s\2", mu->email);
} else {
    command_success_nodata(NULL, _("An email has been sent to \2%s\2 regarding their nickname expiration."), mu->email);
}

sfree(key);

}

void check_nickname_expiration(void) {
mowgli_node_t *n;
struct myuser *mu;

MOWGLI_ITER_FOREACH(n, myuser_list.head) {
    mu = n->data;

    if (mu->registered + (10 * 86400) > CURRTIME && mu->registered + (11 * 86400) <= CURRTIME) {
        send_expiration_email(mu);
    }
}

}
