Yes, you all want me to open ports. I'm sorry guys, but I won't budge:
- Opening a port means reconfiguring the firewall. You may find it funny, but some non-profits have no firewall, just a standard ADSL router. The ones that the telecom company provides often has no IP filtering abilities.
Read your router manual, you can easily only port forward from a single or multiple ips to your local
- I will not expose an SMTP server to the outside word. I will not install in, or advise to, a small business a piece of software that craves for attention
The problem is your knowledge is limited, and therefore draw incorrect conclusions. So maybe try and find someone that has more knowledge in your group, or ask around in your charity.
- Of course I can ask the current ISP. And they may comply. But how about the next one?
What next one? You should stick with your ISP for years, I have.
- Of course I can filter my provider's IP in some Linux firewall. But then the provider will change its setup and won't tell me. Or I will not have time to modify the configuration. Or the next person will not have time just this week.
These things do not change. I did not change my mail ip's the last 10 years or so. I guess only 'hillbillies' that hop around from supplier to supplier to cut a few dollars a month do this.
