Software(s) to send e-mail from outdated e-mail client?
 

I've made a post about this a few weeks ago. But it was a bit vauge. So I'm reiterating and making a new post

I have an outdated e-mail client, that does not support TLS and uses a very old form of SSL. Is there a server software solution to allow me to send mail using this internet client again? I'd like to do this by inputting the server address as the outgoing SMTP address and send/relay the e-mail to Gmail

I'd also like others to be able to use this solution, again, by only having to input the server address as the SMTP address. For minimal setup and hassle. This e-mail client is for an old game console

There is one solution using CMailServer on Windows. Which does exactly what I'm asking. But it's a hassle for many people to setup and each mail user/password must be defined. I'm looking to send the e-mail from the old client, and the server will relay the e-mail to gmail without needing to define or store user information

Thanks for any help, I've been trying to figure this out for awhile

am i understanding correctly that you need to send email to an address that allows sending unencrypted mail? because the email client can't provide that?
so why don't you just open an account with a provider that allows that?

also, it would really help to know more about this mysterious outdated client.

With first time reading I did not get anything. However, as I read twice you need to setup mail server which will allow email clients to send email (Out dated email clients) which does not support TLS? Like CMailServer on Windows which setup the email server. by the way most email software used SMTP on port 25 to submit messages in plaintext.

Which outdated email client you are using? Can you give more information as requested?

In my reply to your previous I never saw how you setup stunnel. BTW relay has a distinct meaning when speaking of email and your use of that word is not the email specific meaning. Use stunnel as a proxy between the old email client and gmail.

You may be able to use other tools but I think stunnel is the simplest to solve this problem.

Hey apologies for still being vague

I'm using an e-mail client(s) for Sega Dreamcast. All of these clients are from 1998-2001. Many games have the ability to use these clients on the game disc. There's a few ideas I have to make use of this if I can figure out an easy/minimal setup for others

None of these clients support TLS. The latest client might support SSL, but for compatibility with the oldest versions, we'll just say that none of them support SSL either

As stated I've done this successfully on CMailServer on Windows. But the issue with that is your PC and the CMailServer must be running to use it. So even after you setup and config, this can be a pain for other "casual" users

I need the e-mail client to send mail to an alternate server, which will then forward/relay/send the mail received by the server to Gmail (or AOL because Gmail recently seems to have changed where the Dreamcast clients no longer support Gmails IMAP, fetches mail infinitely. It has worked in the past)

There is two approaches I've been looking into but can't find anything that suits what i'm looking to do. Or I don't understand

Approach #1) The main way everyone plays Dreamcast Online is with Raspberry Pi software called DreamPi. Which with a USB modem can automate a RAS dial-in internet connection. I can SSH and install whatever GNU/Linux software

So in this approach I could send mail from Dreamcast e-mail client at 1.2.3.4, to Raspberry Pi adapter at 5.6.7.8, and forward this e-mail to another e-mail provider. This would require a bit of setting up for the user, but then they can forget about it. I'm also going to be making a very detailed how-to if I can figure this out

So:
E-mail sent from 1.2.3.4 --> Local SMTP server at 5.6.7.8 ---> E-mail provider's SMTP server --> E-mail recipient

Approach #2) This would have the most minimal setup for other users, but I'm worried about security and using the SMTP server as a host for spammers. The e-mail sent from the client would be sent to an external SMTP server hosted by me on the internet, and would be relayed/forwarded/sent to the proper e-mail provider SMTP server. The user would just have to set the outgoing mail server to my server address

So:
E-mail sent from 1.2.3.4 --> External SMTP server on interet --> E-mail provider's SMTP server --> E-mail recipient


Anyone have any advice as to how I'd go about doing that? I hope that is enough info. And thanks for the replies

I had a similar problem and solved it a few years ago by installing my own mail server using sendmail and dovecot. The instructions were easy to find and there wasn't any rocket science to the installation and configuration. My client is part of a database application written way back in the early 2000's. It's used to send invoices and statements to customers. I'm currently working on an updated version using PHP/MySQL a new server using Postfix/Dovecot with SSL support.

Most people do not do this and rightly so. I learned the hard way about spaming and dealing with block lists from various outfits including Barracuda Central and Spamhaus. But we do not do these things because they are easy. ;)

I settled on iredmail. A minor changed in its configuration file allowed to it to support port 110 and 25.
