I have a big problem, my hosting company block my port 25 every week becouse of spammers.
Users register and then start spamming. Is there any way to fix this ? Please gave me advice or plugin to deal with that ?
Was thinking first for reCAPTCHA when user try sent email but dont know if that is possible ?
If it is that maybe solve spam problems against bots.
Also i have Spam Assassin installed but not do any good.
Please any advice will be great.
