We have a client who is battling with their ISP's SMTP daily email limit and we have suggested they set-up their own SMTP server (Theres the problem).
Our client currently has around 825 customers and due to the volatility of their raw materials they regularly notify their customers of price changes - this is essential to their ordering process.
The problem they are facing is that their ISP only allows around 300 emails per day to be sent through their smarthost and normally this is not an issue as these clients can be emailled over 2 or 3 days but this is their busiest last 1/4 of the year and as such raw marterial prices can change daily sometimes which means by the time the customer receives their updated price its out of date and they struggle to send more as they hit their daily limit.
I have suggested they set-up their own SMTP server in-house and use this for sending their email however I have one issue and two questions.
Firstly the Issue: Can anyone please advise me how to set this up - preferably with Server 2008R2 or Windows 7.
The Questions: -
Will this allow our client to send more emails each day without being hit by their ISP's daily limit of 300
If it does - how does this work - does the email still go out on port 25.
Thanks and Regards
