Postfix can not fetch mail.

I can't? The original design of 'sendmail' deemed that it was more efficient to do a turn-around to lush queues in both directions once a link was established. That was then! This is **NOT** a requirement, it is an option. It is one I don't use but have configured in 'sendmail' in the past. (*sigh*) These days I use fetchmail. I find it more flexible an can deal with sites that SMTP is a hassle for. The original sendmail used the TURN command,,later versions, like Postfix, use ETRN, based on RFC1985, "SMTP Service Extension for Remote Message Queue Starting", DeWinter J., 1996/08/14. This discuses the TURN and ETRN commands. <quote> This command uses the mechanism defined in [4] to define extensions to the SMTP service whereby a client ("sender-SMTP") may request that the server ("receiver-SMTP") start the processing of its mail queues for messages that are waiting at the server for the client machine. If any messages are at the server for the client, then the server should create a new SMTP session and send the messages at that time. </quote> There seem to be some different interpretation of this. Since ETRN was intended to address security concerns with TURN, and since the later did only weak (read none) authentication, some implementations have chosen to ask the server to call back and then drop the connection. Sadly, this is not something that works with the kind of dial-up connections that this service was intended for. Rather than say "it can't" I prefer to say that it is not part of the normal configuration and not a good idea for a number of reasons, unless you have specific requirements. Unless you are a backbone gateway between, say AOL and HOTMAIL and GMAIL, I wouldn't bother. There are going to be simpler, more easily understood, configured and maintained way of working. Fetchmail is good! Really Good. As I've discussed here before, I still think that Postfix (or exim for that matter) is a big and complex footprint or someone running a workstation and using Thunderbird or Evolution as their MTA. All Postfix is doing is handling the system generated messages, and it is a HUGE overhead or that. If you're running a server or a gateway, its a different matter. -- Our country is now geared to an arms economy bred in an artificially induced psychosis of war hysteria and an incessant propaganda of fear. -- Douglas MacArthur -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

And? What's the problem with a tiny bit of overhead? 20 years ago it might have been an issue worth dealing with, but today it's just not of any relevance. IMHO.

Its nothing on the 2G/160G of my 17" desktop replacement laptop or even bigger machines that people have on their desks. It does matter to the 1G/16GSSD 7" netbook. The solution seems to be to not run openSUSE. That may also be a solution for some people frustrated with 11.1 and Novell's attitude towards KDE. I can see a lot that bubbling beneath the surface in postings here. One size doesn't fit all. Bigger is not always better. And as this thread shows, there is the complexity issue quite separately from the size of the footprint. Even if Postfix were a fraction its size, all the config files, their interactions ... are heady stuff for someone who isn't dealing with that kind of thing every day. There's a subtext of arrogance towards the plain users by sysadmins. Most users - even Linux users - don't want to spend their days hacking away at config files. Many of us had good working KDE configuration and now we have to hack away at new configurations for KDE4. And so it goes. -- "Current economics is merely refining the obsolete.

I run postfix on a 16 year old 486DX2 with 24Mb RAM. Postfix does not present any significant overhead - uses hardly any CPU, about 6M of virtual memory and 10Mb diskspace. Surely a modern netbook can handle that too.

I have it running on a Intel P3 (1GHz) machine and there is no problems with overhead, but to get this back on topic I just needed help fixing a late night mistake, and if disabling fetchmail is all I need to do then this problem is solved I didn't expect this thread to get this far off topic where people would try and work KDE4 into it (which I am happy with both my desktop and laptop run it). -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAklaUFoACgkQRMKiLy/EUZSkFQCgmquXBPXHqDCKuAQ7d+AyJk/3 ODcAoKPWBHkxEelb+KsBaDqAeZl4gM6W =Lmf2 -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
