Can someone explain what is the purpose of "Postfix3"? It's just the latest version of Postfix, the reasin it's called "postfix3" is historical: Back before the release of Postfix 3.0 GhettoForge used to ship the package as postfix, the problem was that postfix prior to 3.0 did not have loadable dictionary types, so in order to provide support for every dictionary type the package had to compile it in, and have requirements of every lib under the sun for it. When 3.0 added loadable dictionary types I was able to package them under separate binary packages such as postfix-mysql, postfix-pgsql, postfix-pcre, etc. This allowed me to remove those from the base postfix package. The problem with this is that there were a number of people who already used postfix from GhettoForge and if they ran a "yum update" command they would have found their email servers breaking very quickly because the postfix package lacked the dictionaries that used to be compiled in. The solution was to release future postfix packages as postfix3, so that people in this situation would not have the above mentioned surprise breakage and when they updated they could install the individual dictionary packages that they needed. After that EL8 was released and for efficiency sake it is easier to build the same package names from the same source rpm rather than have a package named "postfix" for EL8 and "postfix3" for EL7. So that's the story of why it's called "postfix3" now. Are there other options (repos) for getting current versions of Postfix using dnf on a RHEL system? I have heard of the odd repo having it, but I would not recommend them over GhettoForge. Of course I'm biased. Also I believe that Red Hat intends to release newer postfix versions as module streams in later EL8 point releases, but they will not be as current as GhettoForge is.

EL7 uses yum, EL8 uses dnf, but it comes symbolic linked to yum, so the same yum commands that work in el7 also work in el8, even though you are, in fact, using dnf. The commands on the page use yum because they work in both major releases and so it avoids having to put separate commands for EL7 vs EL8 examples. post...@ptld.com Wrote: Wait, so its a fork of Postfix?

To my knowledge, it is the same code, unpatched. It's whatever the maintainer of that code wants, intends, etc. Why not ask the maintainer? The maintainer is on this list, but due to time zones and perhaps personal circumstances has not been able to reply yet. You can also find him in irc.libera.chat/#postfix as "pj". -- http://rob0.nodns4.us/

All the patches are included, the .spec file is included and postfix source is included (it's official postfix source, i verified the checksums). I use the repo on some installations and I am very happy with it. I do not know about the name, but if I had to GUESS, it's called postfix3 because rhel7 has postfix 2.10 (or something) by default. So the name indicates a major version bump. It's pretty common in rhel world. And it remained named this way rhel 8 for convenience? Just ask the maintainers. They include a contacts and mailing list, irc channel. There is also email in specfile changelog. Please don't speculate. J.

[snip] likely at least a minimal attempt to avoid naming conflicts. renaming forked the code (hopefully) helps avoid blaming Wietse for whatever gets broken in that fork. renaming forks should reasonably be a common practice. -- jd
Re: GhettoForge Postfix3
It's "postfix3" so it does not conflict with the RHEL/CentOS system "postfix" package.

If it's a repo providing the same Postfix as every other repo why does it have a 3 as part of the name? People usually rename a product to distinguish its different. Why would one (using their yum examples) have to remove Postfix and install Postfix3? Why wouldn't you just update postfix and be done with it. This is what causes me to wonder.

Re: GhettoForge Postfix3
Are there other options (repos) for getting current versions of Postfix using dnf on a RHEL system? fwiw, use existing pkgs from https://src.fedoraproject.org/rpms/postfix for 'Fedora ELN, if that fits your needs or rebuild & package from those sources, or your own tweaked/modified .spec, on your own COPR (https://docs.fedoraproject.org/en-US/infra/sysadmin_guide/copr/), specifically for your chroot of choice Fedora COPR certainly a variety of EPEL chroots, including 9, https://communityblog.fedoraproject.org/epel-9-is-now-available/ i regularly rebuild the rawhide sources, which only slightly/ocassionaly lag new Postfix releases, for F35 for production use; works a charm.
