I’m looking for a simple sendmail replacement to receive local mail, such as from cron and service failures and forward it to on to a real SMTP server.
I have used msmtpd successfully but thought I’d ask if folks have other solutions they like.
You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: !selfhosted@lemmy.world
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don’t control.
Rules:
Be civil: we’re here to support and learn from one another. Insults won’t be tolerated. Flame wars are frowned upon.
No spam posting.
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it’s not obvious why your post topic revolves around selfhosting, please include details to make it clear.
Don’t duplicate the full text of your blog or github here. Just post the link for folks to click.
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
Postfix.
I use proxmox mail gateway (PMG) for my homelab, configured to relay through my Gmail domain using smtp auth.
I’ve also used PMG at the enterprise level. Never had an issue with it.
It’s postfix underneath.
I run Mailcow-dockerized for my mail server and internal relay, and it’s a postfix based system. Never have any issues with it.
