Re: [SLUG] Email Server
First, lets verify with the maths: a 56K modem's uplink is 33.6Kbps, 10 bits per byte [due to Async framing]. thats a maximum transfer speed of 3.3KB/sec. your 12K message would take approximately 3 seconds (actually, a little over) to transmit. Next, let's re-verify the maths. Async framing went out with the loaves and fishes. Ever since MNP4, modem links have been synchronous, clocking in at 8 + epsilon bits to transfer each byte of data. But wait, there's more! Ever since MNP5, modem links have been compressed. Modem compression isn't really worth all that much, except in the very limited realm of repetitive plain text. Like email, to pick a random example. And what better way to make it repetitive than to send the same thing to n destinations? The point is still valid regardless of the transfer method. Yes. Aliases are most easily managed via the older aliases style. They're more space efficent. And I'm sure sendmail's alias hashes are faster to read too. By one person, for one person, yes. The thing about virtual domains, see, is that they're usually for the benefit of multiple owners. And these multiple owners, pesky and arrogant individuals that they are, want to make changes to delivery rules at odd hours of the morning with depressing regularity. There's something very, very appealing about putting all the control for any given domain in the hands of a separate user, and then washing your hands of the matter. But then, I'm an anti-control freak. black vs white. choose whats appropriate, thus the value of opensource. And the qualitative difference between monitoring disk space alone or disk space and inode count is what, exactly? The median mail message weighs in at 3-4k in size. The average big ext2 filesystem comes formatted with one inode per 4k of disk space. Good match, wouldn't you say? If your running big mail servers lots of disk is important anyway, but saving it is still good. mbox isnt great, i like maildir and most apps have been adapted or writen for maildir support. qmail can run as mbox anyway, and if your really desperate you could just pop into your local machine. Also, most POP3 and IMAP daemons work with mbox, not mailfolder. Same with mailreaders. Boggle. How many POP3 daemons do you want to run? They don't exactly vary a huge amount in terms of featureset. As for IMAP - I can think of three major open source contenders off the top of my head. Of those, one may or may not be mbox only, but shouldn't be touched by a ten foot pole (as a security expert, I'm sure you know which one I'm talking about), one is maildir only, and one uses it's own entirely funky storage subsystem and glares daggers at any foreign software. There are pop / imap servers for both. what does it matter how many there are? And *NO* high performance system should ever run out of a inetd/tcpserver style system. You're introducing unnecessary overhead, and this *WILL* force your load up every time. Somebody go and count the cycles involved in half a dozen fork/execs - /especially/ under Linux - and compare it to the cost of fsyncing one block of data to disk. Reality check? depends on how things are implemented. No doubt some poor coding would make an inetd/tcpserver solution higher performance. and lazyiness is not an excuse. I don't care how much "more complicated" it would make qmail to do multiple envelope delivery, its is irresponsible to waste bandwidth when you could be saving it. Especially here. You've said a lot about mailing lists, and, with all due respect, grossly misrepresented dib's view on them (which directly relates to how and why qmail does what it does).

This is the CGI vs persistant application server argument. The Persistant application server won last time I looked. Like I said, I'm not arguing just for linux, but as it has been pointed out, there is a standalone mode for the smtpd - so this arguement isn't that valid anyway. Also Reinvoking applications rapidly is guaranteed to push your load averages up, even if its not a performance hit. If you're running load average monitoring as part of a network management system, and you're not careful with your trigger thresholds, those alarm bells are going to sound a little prematurely as a result.

Just don't run a version with known vunerabilities, and keep an eye open for advisories [like any good sysadmin should]. And which version would that be? IIRC, 8.9.2 is fairly good. I'm sure others will be able to tell you which versions of sendmail are "safe". Bwargh. If I hear another "qmail is good" rant, I'm gonna barf. I'm not going to dispute smail, postfix or exim, or any other mailer I have no experience with. qmail is not good. qmail is disgusting. Why? I think you're wrong. The way it is setup takes getting used too, but it works, amd works well. qmail is incrediably network inefficent[1]. No, it isn't. It can hardly be called inefficent when it delivered a 12K message to 5 recipiets on 5 different mail servers in just under 7 seconds. I had to pick my jaw up (my 56K link is flaky at the best of times.) First, lets verify with the maths: a 56K modem's uplink is 33.6Kbps, 10 bits per byte [due to Async framing]. thats a maximum transfer speed of 3.3KB/sec. your 12K message would take approximately 3 seconds (actually, a little over) to transmit. The fact you sent it to 5 distinct hosts, in under 7 seconds immediately indicates that you are mistaken about either the time to deliver to all 5 recipiants, or of the size of your message. If sendmail was transmitting to a smart-hub on the other side of the modem link, it would take the 4 or 5 seconds - the message would be sent as a single envelope to the smart-hub for further processing. Otherwise, you'd be looking at a minimum of 5*3 = 15 seconds to send it to each distinct host. Qmail, however, doesn't support multiple recipients for envelopes, so those 5 recipients become 5 distinct envelopes. All 5 envelopes must be delivered seperately. You automatically take a minimum of 5*3 = 15 seconds to transmit that 12K message. This also affects smart-hosts under qmail IIRC. qmail does address aliases in a truely disgusting manner (whatever happened to just using /etc/mail/aliases and ~/.forward, hmm?). Having to create 'users' just to contain mail alias folders is just plain stupid. "echo 'username' /var/qmail/alias/.qmail-alias" is plain stupid? Apart from the fact its actually ~alias/.qmail-alias, or if you're running virtual domains, ~vhostaliasuser/.qmail-alias, yes - it is. More uncessary inode and disk space wastage - each of those files is a minimum of one block, and use one inode. Yes. Aliases are most easily managed via the older aliases style. They're more space efficent. And I'm sure sendmail's alias hashes are faster to read too. The `mailfolders' message storage scheme is just plain filesystem unfriendly[2]. Only because it uses one inode (or more) per message, but it's _fast_, and works well. Hence why its bad. For large sites, you constantly have to watch the inode free count on the mail volume. With sendmail or mbox systems, one inode per spool, just watch your free disk space. Also, most POP3 and IMAP daemons work with mbox, not mailfolder.

Pure and utter FUD. My mate's cable box runs qmail, and when cable went down for 4 hours, and he had a outgoing queue of 150 messages, when the connection went up, it delievered them all faultlessly, and gave the system a 0.4 load average (Pentium 120, too) We run a host with multiple (read 3) spools, tuned for *very* large spools and queues.

Re: [SLUG] Email Server
If you are at all concerned about security, then you really only have two choices qmail or postfix. I am told that the setup and operation of postfix is quite similar to that of sendmail... Qmail is very different, but I like it. The licence it is under, makes binary distribution basically impossible, but if you follow one of the howtos its pretty straight forward. There are addons if you would like /etc/aliases support and the like. I would suggest courier-imap for imap, imaps, pop and pops. vpopmail can automate virtual domains for you, and qmail-admin provides a web admin interface. sqwebmail gives you web-mail. (And if you are feeling particularly keen, wrap your Maildir directories up in a Resierfs, for some excelent performance) Check out www.inter7.com and www.qmail.org for links to most of this stuff. -Colin Dean Hamstead wrote: sendmail is installed on most systems by default.

OK, First of all - this reflects my *personal* views, because I know people are going to jump and and down, and complain about what I'm going to say. Sendmail should be your first choice for an MTA. Sendmail is moderately efficent [especially when compared to qmail], keeps on working, is easy to install, supports Virutal Domains, etc - and is easy enough to configure once you know how (Yes, there is a "secret" that would be better known if people bothered to read manuals). 1) Installation. Use whatever package you have for sendmail with your system. If you can't use that, download a recent release, and compile it following the build instructions - they've worked on everything I've thrown it at in the past. If you are building, be sure to build (or install) Berkeley DB *first*, since hash map support is a Good Thing(tm). 2) Configuration. look at sendmail.cf, release that its the most disgusting format ever, then ignore it. Use the m4 scripts instead. (The m4 scripts are the secret to an easy configuration process). The m4 scripts are also very well documented - and you should definately read their manual. Fortunately, if you get things right, you only ever need to do the sendmail.mc and cf files once ever - and configure everything else elsewhere. You probably want to enable the cw file (local hostnames), virtusertable, mailertable, and accessdb (relay/block control) features at least. 3) Virtual hosting. Sendmail has two features for this. Virtual Domain handling for inbound messages is handled via the virtusertable. Virtual Domain handling for outbound messages is handled via the mailertable. Read the quick overview at sendmail.org. The sendmail system is quite simple and powerful. The main thing to remember is to run makemap to rebuild the tables after editing them. 4) Web Admin Interface Are you nuts? What would you want such a beast for? It should be trivial to write a CGI/PHP/Mason system to edit virtuserhosts, mailertable, access table, etc though. Sendmail, once its running, is incrediably easy to look after though.

Just don't run a version with known vunerabilities, and keep an eye open for advisories [like any good sysadmin should]. Qmail is very different, but I like it. The licence it is under, makes binary distribution basically impossible, but if you follow one of the howtos its pretty straight forward. There are addons if you would like /etc/aliases support and the like. I would suggest courier-imap for imap, imaps, pop and pops. vpopmail can automate virtual domains for you, and qmail-admin provides a web admin interface. sqwebmail gives you web-mail. (And if you are feeling particularly keen, wrap your Maildir directories up in a Resierfs, for some excelent performance) Bwargh. If I hear another "qmail is good" rant, I'm gonna barf. I'm not going to dispute smail, postfix or exim, or any other mailer I have no experience with. qmail is not good. qmail is disgusting. Why? qmail is incrediably network inefficent[1]. qmail does address aliases in a truely disgusting manner (whatever happened to just using /etc/mail/aliases and ~/.forward, hmm?). Having to create 'users' just to contain mail alias folders is just plain stupid. The `mailfolders' message storage scheme is just plain filesystem unfriendly[2]. qmail's smtpd via inetd is inefficent, making you use the author's silly tcpserver thing (which is just as bad IMO). More cruft to install. :/ When under heavy mail loads, qmail will happily blow a single processor PIII system load up to 60+. This basically renders loadaverage monitoring useless. All this said and done, qmail's only redeeming feature is that it flushes its spools moderately quickly. Mind you, in my eyes - thats its only redeeming feature. [1] The "Lets send out multiple recipiants as individual envelopes" idea is just plain stupid. [2] unless you're running your mail spool on reiserfs, which is NOT recommended given that reiser is still not "stable". -- --==-- Crossfire | This email was brought to you [EMAIL PROTECTED] | on 100% Recycled Electrons --==-- -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://slug.org.au/lists/listinfo/slug
Re: [SLUG] Email Server Questions
As I understand it, you don't. You just set it up as a mail server that collects the mail and passes it onto the main later, or have your clients poll it as well. However, it still relies on bigpond, or whoever provides your MX records listing your secondary mail server in their nameserver and if the problem is their nameserving, then you are still stuffed. Thanks terry, thats what i wanted to know. Funny how quickly this went around after i got off the phone bitching to tech support and being told nothing was wrong.

You just set it up as a mail server that collects the mail and passes it onto the main later, or have your clients poll it as well. That is how I saw it; you set your secondary server exactly the same as the primary one, but perhaps with a cron job that polls the primary server, and sends the spool off to it, so your users need have only one place to collect their mail from. -- jamesw Usenet is essentially a HUGE group of people passing notes in class. -- R.
