The goal is pretty simple. The situation is probably pretty common. I have multiple email accounts configured in my email client. Each is configured to use the SMTP server for the corresponding domain. Depending on the location of me and my laptop, I can send through some SMTP servers and not others. At work, I can send through work SMTP, at home I can send through my ISP SMTP server, etc...
If I'm at a random public wifi access point, I generally can't use any of my SMTP servers.
Naturally, I'd like to send mail from any location without having to go through and change my SMTP servers each time I go somewhere new.
I set up a local mail server on my laptop, and it works fine. But about 20% of the time, my mail is rejected as many servers block incoming mail from large ISP IP blocks.
Does anyone know how to configure a sendmail server to allow relaying from a specific domain/ip address/email address?
I have my own dedicated server, and I've tried to configure sendmail to relay messages from my laptop. I've configured rules in /etc/mail/access like:
Code:
Connect:12.34.56.78 RELAY
Connect:mydomain.com RELAY
From:me@mydomain.com RELAY
Connect:12.34.56.78 OK
Connect:mydomain.com OK
From:me@mydomain.com OK
None of this works.
From all the docs that I've read, sendmail really only wants to deliver mail to domains hosted on the server itself. I appreciate this anti-spam approach, but I want to send mail!
I'm sure there's someone as ignorant about sendmail as I am who has solved this very same problem in a simple way.
On a side note, are there SMTP service providers for users like me that someone would whole-heartedly recommend? If I can't get sendmail to do what I want, I'd happily pay a modest fee for someone else to provide the functionality I'm looking for. But it would have to be a very reputable company as I know this type of service would be a natural haven for spammers.
