Viktor, sorry.. and thank you. another dumb question: so if I have 25 clients on a NATed LAN, that's my connection count limit, isn't it ? and I think I've found my problem: when they changed IP on the site, I forgot to add IP to: smtpd_client_event_limit_exceptions = 147.50.1.226 if I have it here I don;t need to worry about the other limits, isn't it? thanks again V
