[gentoo-user] Postfix to relay mail even if acting as primary MX host?
Okay, I'm still scratching my head here. Scenario: Having a Postfix server in the cloud to act as the primary MX, but actually forwarding the emails to my company's email server behind the firewall. For the purposes of my scenario, here are the relevant (but mangled) settings: *) Domain is example.com *) Postfix server is mailer.example.com with the IP 55.66.77.88 *) Company email server is accessible via 11.22.33.44:5225 *) Firewall only allows incoming traffic to 11.22.33.44:5225 from 55.66.77.88 *) I want to set MX for example.com to mailer.example.com I saw the relay_domains and relayhost settings, oh good. But then I ran smack-drab to the following NOTE: # NOTE: Postfix will not automatically forward mail for domains that # list this system as their primary or backup MX host. See the # permit_mx_backup restriction description in postconf(5). So, if I set relay_domains = example.com and relayhost = [11.22.33.44]:5225, yet have mailer.example.com as the primary MX for the domain example.com, the emails won't be relayed to 11.22.33.44:5225, right? Can anyone help me configure Postfix to actually do what I want, e.g., to *still* relay emails destined to @example.com to the address 11.22.33.44:5225? TIA.

Re: [gentoo-user] /usr/bin/[ and coreutils
Yes, it's a different binary, and it's perfectly usual to find it in a Linux system. But note that, at least in bash, you rarely will be using /usr/bin/[ unless you reference it using the full path (either in a relative or absolute way). This is because bash has a builtin that takes over that binary file. You can check that (or any other command) by using the type instruction (again, this is for bash). # LC_ALL=C type [ [ is a shell builtin The same goes for 'test'. Those binaries are probably there just in case that some init or system script written for a standard bourne shell (like the busybox one) needs it. But don't take my word for it.

Up to you; slot conflicts are outside my area of knowledge for Gentoo.
The dmesg error you had suggests to me that the problem may be in
libmozjs. It could also be in a badly-built data structure passed
*into* libmozjs, though, so I was looking for some differential to see
which had the problem.

hmm, for sure your problem is not video-related then.
gjs is the javascript-bindings for gnome...
You could try keeping spidermonkey at 1.8.5 and (re-)build the latest version
of gjs.
google-ing your problem clearly shows: you are not alone. Sadly I was not able
to find a solution for your problem yet as most others use ancient versions and

I only report what I read. No tests done so far. Shouldn't discard be set to make TRIM work anyway, even with fstrim? man mount says for discard: Controls whether ext4 should issue discard/TRIM commands to the underlying block device when blocks are freed. Sounds like TRIM-commands wouldn't get through to the SSD when discard is not set. Still wondering. Stefan

Apologies if you receive this twice: In addition to the dog ate my homework, now we have a new excuse, the server are my document :-D Ah, progress ;-) I use it on my laptop (4GB RAM, typically 1-2GB swap used). It works pretty well but I can't give you any hard figures. I wrote my own init script for this. I can share it if you want. Otherwise the sunrise, betagarden and mv overlays offer ebuilds for it. I think the mv version is closest to mine. What makes the proliferation of ebuilds? What has been pretty confusing is that there are two versions: The original one from Google(?) and the one in the mainline kernel. They have different APIs (hint: if you have a userland tool instead of manipulating /sys, it is the original version) and only the original version can use a swap device as an additional backend for uncompressable pages. With the mainline version (which I use), you can only use zram as an additional swap device and give it a higher priority than your normal swap. In the kernel? What .config knob should I twiddle? I do prefer having zram support in the kernel. /etc/fstab: /dev/zram0 none swap sw,pri=1,discard 0 0 /dev/sda7 none swap sw,pri=0 0 0 Only drawback so far: When zram is full, putting the laptop into standby takes longer, maybe 15s compared to 3s without. Sometimes this can lead to timeouts and the kernel aborts the suspend operation with an error on dmesg. Reattempting it then succeeds. Point taken. Do you think it's worth the slight annoyance? Rgds,
