Subject: SMTP server: Routing outbound mail through my ISP

17/07/2007 03:26 jeebs98:
SMTP mail sent from my system to Hotmail (as an example) gets rejected. I am guessing that this is because I have a dynamic IP address. I have another program that lets me route outbound SMTP mail through my ISP, but it is not the all-in-one product that shttps is. How do I set shttps up to route my outbound SMTP mail to my ISP`s server? My ISP requires authentication. Thanks!

Sorry, server don`t support authentication for higher level SMTP server.
In any case for mail server, static IP address is need. Otherwise you can`t receive income messages from external servers.

Thank you for your speedy reply. I am using NO-IP ( to route my DNS name to my current dynamic IP address, so I am able to receive Inbound mail just fine. Is there any plan to allow your product to send outbound mail via an ISP which requires authentication?

I don`t sure. Probably not. First think, -- send messages through intermediate server it isn`t very well, no reason to developing this direction.

Okay - thanks, anyway.

What can I do if my isp blocks port # 25,2525,587,225 and all know smtp ports.

You can send mail with help an external SMTP of your provider. But no way to receive.

You may try to get IPv6 address, create IPv4-IPv6 tunnel, create DNS AAAA record for your MX host and this IPv6 address, and may be you will be receive some messages, but if remote server doesn`t support IPv6 the messages from that server will be lost.

I was thinking did you know of any free smtp relays out there that
I could use but wouldn`t be blocked as spam.

I was trying to setup the hosts file to get it to work with Hotmail with no luck... I added a PTR record, and the SPF record as well, but mails still bounce saying my IP is dynamic... I think there is no solution for this so we must stick with the ISP`s SMTP :(
To lmartin92: the solution to ISP blocking standard SMTP ports is - I use it myself and it works like a charm :)

Probably nobody ask PTR record from your server because your DNS server doesn`t directed as NS server for reverse zone
DNS resolving system ask record from root server, if root server haven`t this record, it say down level authoritative NS server for this zone, the system ask them, if it haven`t record it say down level NS server, etc... The resolving system will never ask your DNS server about record, if up level DNS server for zone of this record know nothing about your DNS server.

ISP provider must add PTR or NS record on his DNS

DNS server in Small HTTP server is full. It is not required another DNS software.
Internal software can`t help with this problem. The problem on the servers of providers that put you IP address. Main DNS servers know next level DNS for each IP area, that servers must know DNS servers for each sub areas in his area, etc., and at the last on DNS server of your provider must be NS record for your IP or PTR record of your IP. Nobody will not ask your DNS server, until up level DNS don`t say that your server is NS server that may know reply for request.
