The one problem with msmtp is that it doesn't rewrite headers, like "From: root / To: root". These are not required for SMTP, but they are required by some mail providers who will reject email that doesn't have an "@" sign in these headers. The author or msmtp has said he does not plan to add this feature.

I worked around the issue with my own sendmail wrapper that rewrites local addresses in From and To headers before passing the message to msmtp. Someone else posted such a script in this bug report:

LXC/LXD can be highly available (HA), stable, work and provide kernel isolation as well (real VMs): https://ubuntu.com/blog/lxd-virtual-machines-an-overview

It's convenient when it works, but with three different containerization technologies, it's harder to debug when Proxmox+LXC+Docker fails. Even running Docker in parallel to LXC rather than nested would be simpler.

In addition to "encryption at rest", also consider that your devices might be exploited over the internet, so attackers may be able to access the decrypted state that way. To guard against that, you may wish to encrypt certain documents with an additional password, even if they are sitting on an encrypted file system.

Recall that within a month, the widely SSH was exploited and a backdoor added to every machine. I had upgraded to that SSH version. I didn't run an SSH server on that box, but it goes to show that even those who take precautions can end up exploited!

How are you certain all your porn is legal?

Thanks. This is just for forwarding from mail and the like, so occasional loss of mail due to lack of spooling could be tolerated.

I need a sendmail binary that sends outgoing mail to an SMTP server with as few other features as possible.

markstos OP , 2 months ago to Selfhosted in Recommendation for outgoing-only SMTP server

Thanks. Turns out it's not in Fedora.

markstos OP , 2 months ago to Selfhosted in Recommendation for outgoing-only SMTP server

I found a nice Ansible role for nullmailer, but found that it is not packaged for Fedora, but msmtp and ssmtp are. I think I may try ssmtp next. Despite its unmaintained status, somewhow it's packaged and nullmailer isn't.

Sendmail is a full-blown MTA released 41 years ago that is notoriously difficult to manage. There are reasons that it's market share has declined from 80% to about 3%. I'm also not looking for a MUA, like mutt. I'm looking for a simple MTA that that only relays outbound mail, like msmtp, ssmtp or nullmailer.

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.

markstos OP , 2 months ago to Selfhosted in Recommendation for outgoing-only SMTP server

Tried that. Yes, it has the feature I need. But it has a rather complex feature set and documentation when I just need to to send my mail to an SMTP server. I ran into problems configuring it for this in the past which were difficult to diagnose due to the volume of config options and docs. That’s what led me to explore tools that had only the features I needed and no more, like msmtp or nullmailer.

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

markstos OP , 2 months ago to Selfhosted in Recommendation for outgoing-only SMTP server

I’m not trying to send mail directly from the host, only forward it to a host that’s prepared to send. I’m using Mailgun for that.
