Gordon,
Thx much, yes I have been through the CentOS-new-server dance a 3-4 times over the last 10 years or so.�� It is somewhat painful, but doable.
��
Interestingly enough I just installed a FreeBSD VM this morning and have been ���playing��� with setting it up for exim4u.�� I was almost lost at first, started some googling, etc. and it all started coming back from my Unix days (Sequent, HP and then SPARC). Getting along well with it now, and your recipes help a lot.
��
I will probably just stick with this if it all works well without too much jumping through hoops.
��
Thanks for creating/maintaining the exim4u tool, even though I have not quite gotten to using it yet (maybe tomorrow!).
��
Helmut

Hi Helmut,
Exim4u should run successively on FreeBSD or any of the leading Linux distros.�� Personally, my preference among the Linux distros would be Debian and I like FreeBSD Unix very much too.�� I currently am running several Debian installations along with a FreeBSD installation.
These days CentOS, or any of the Red Hat derivatives, are probably the most stable operating systems around. After all, Red Hat is now doing a multi-billion dollar business annually selling Linux services and support to large enterprises world wide. Fortune 500 companies can not afford buggy software and/or updates and that is the quality of the software that you will get with any Red Hat derivative including CentOS.
I ran CentOS on alot of installs up until a couple of years ago when I started migrating away from that.�� The great thing about the Red Hat derivatives, such as CentOS, is that it is supported for 10 years (without upgrade) and it is ultra stable in that you will never get an update that includes a hiccup, which is not the case with most other Linux distros such as debian and FreeBSD as well.�� The bad thing about CentOS is that all of the software is seldom upgraded beyond the initial release except for security updates and bug fixes.�� For example, if you were to start with Exim 4.82 on a given CentOS install then that is what you will have for the entire 10 year life of the OS. There are other repositories, such as epel, which offer current software versions for CentOS but that can introduce other problems as well.�� Also, with CentOS, you can not upgrade from a major version of CentOS to another.�� For instance, you cannot upgrade from CentOS 6 to CentOS 7, etc.
On the other hand, with FreeBSD or Debian, a major upgrade is offered every two years to the then current OS version and which provides current versions for all included software packages too.�� Don't get me wrong, there can be problems with these biennial upgrades as well, however, the whole idea is for the upgrades to be successful with minimal problems and disruptions.
So, if your primary objective is stability then you cannot beat CentOS.�� However, if you go with CentOS and want to keep fairly up-to-date with your software, then you will need to build a new CentOS install from scratch every three to five years or so since you can't upgrade it and most of the software that you have is whatever you started out with (except for security updates and bug fixes).
FreeBSD is a really cool operating system and fun to work with.�� WIth FreeBSD, you will get current releases of most software, including exim, within days or a few weeks of release. Its also very easy to customize FreeBSD software packages any way that you want with the FreeBSD ports collection.�� So, if you want to run the most current software available and be able to customize the source and easily recompile any application package then you cannot beat FreeBSD.
For me, I have come to the conclusion that Debian provides the best blend of current software and stability. Nevertheless, I would never want to be without a FreeBSD installation for experimentation, testing and to just have fun with.
Good luck!
Gordon

Personally, I am running all mail servers with exim4u on FreeBSD.

Maybe you should just give it a shot and install it as trying exim4u gives you more information and ���feeling��� than all discussion��� installing is not that much work.

Odhiambo,
You brought up an interesting thought/question.
��
I have been a CentOS fan for many years, essentially since I moved off of SCO Linux and Solaris(for SPARC).�� But now with the implementation of system and its pervasity, I have been looking at/condsidering other OS���es.�� BSD and Gentoo are the primary two.
��
For systemd, most if not all of the mainstream linuxi are already on systemd.�� Here are a couple of links for some systemd background:

��
Probably best to not bring up opinions on system.�� It has and can cause irate comments.
��
What OS are most people running for vexim and exim4u?

Hello,
First message here.�� I am looking to get off of qmailtoaster (been running it for many, many years) since even it is not well maintained any more.
��
I am looking at either postfix or exim, and an easy tool to manage them (limited free time=hobby business).�� I ran across exim4u and it looks like it might fit the bill.�� Other platforms I am looking at are ISPConfig and BlueOnyx (yes, I know, sendmail), Xeams, Virtualmin.�� I know all of those are not email only, but I hope I can just ignore the other portions of those application stacks.�� I do like that exim4U is first for email, exactly what I want/need.�� I do have a couple questions:
��
1.������������ Is it maintained and being further developed?�� I am not concerned if it is slow development, but what exists should be relatively solid.
2.������������ Will it run on CentOS7 or other systemd platforms?�� Seems they are all pretty much going that way unfortunately.
��
I don't know what systemd is, but I will google. I use FreeBSD mostly. Exim runs on Ubuntu. However, Exim4U requires just php+apache+mysql IIRC. If those are installable on a systemd OS, then it will run. Exim as an MTA should run on all *nix OS IIRC. So I guess you have no problem ahead with Exim4U.��
