Comment on Recommendation for outgoing-only SMTP server
hperrin@lemmy.world 8 months ago
You want an SMTP relay. You can use a free public SMTP relay, or make one yourself. If you make one yourself, don’t keep it open, or spammers will abuse it. If you’re sending mail properly, you’ll need to add it to your SPF entry in your DNS. If you’re just sending mail for yourself, you should be able to set up a filter in your email provider so that it doesn’t get rejected.

I have an SMTP server. I need a sendmail binary that does one thing well: send the message to the SMTP server.

Can’t you use sendmail? Also, check out my updated message above. You’ll need to make sure you can send outbound traffic on port 25.

Sendmail is a binary provided by a mail system and no mail system is installed by default on Fedora.
I’m looking for a solution that’s as simple as possible: provide a sendmail binary to pass the message to a third-party SMTP server.
I’ll connect to Mailgun via TLS— no port 25 involved.

Not sure if it’s in fedora, but I use nullmail as my mta. Simple to config and does just MTA

Sendmail is provided by the
sendmailpackage in Fedora. Here’s some instructions on installing and configuring it:tecadmin.net/install-sendmail-on-fedora/
