I've got another problem on my Solaris machine
(5.7), and this time I get a "Aack child crashed" when I try to send to local
users. Below is the trace output (truss) of qmail-lspawn. Please can anyone
advice what this might be? There is no .qmail file so that can't be
it.

Hi all
I have downloaded the Autoresponder and seem to be having a spot of trouble
with it.
my Qmail lives in /var/qmail/
I compiled the autoresponder on a RedHat 6 server and then copied it to a
Jurix Server.
My alias file looks like this
|autorespond 1 5 /var/qmail/alias/AUTORESPOND/MAJORDOMO/majordomo
/var/qmail/alias/AUTORESPOND/MAJORDOMO
&[EMAIL PROTECTED]
When i attempt to send a message to the alias, i get the following.

Well, another advantage of using tcpserver for pop as well is, that you can rather easily implement things like smtp-after-pop-relaying using Russel's scripts and patch for checkpassword or the pam_exec.so.

qmail local-error test failed
Hi! I followed the instruction by install.xxx text. Everything's OK until local-error test. When I sent a mail to an nonexistent local user, I didn't have a bounce message in my maildir. I saw the syslog, there was an error message _Unable to chdir to Maildir_ instead of _No such address_. What's wrong. I hope someone can help me! Thanx: Ernyo

Thank you Soo Aun MediaManager Pte Ltd
Re: Pbl with control/locals
Is there an MX record in DNS for educast.com.sg? Where does it say the mail should be delivered. You should have a DNS entry like this: educast.com.sg. IN MX 10po.monja.com.sg. po.educast.com.sg. IN MX 10po.monja.com.sg. If there is no MX record, the SMTP protocol requires that the mail be delivered to the machine identified by the A record. This is NOT what you want in this case.

Re: Pbl with control/locals
My administrator had set DNS for educast.com.sg with this entry educast.com.sg.INMX10kids.monja.com.sg. INA203.127.238.161 kids is the host name of monja.com.sg. Is the problem lies on DNS setting. My understanding is qmail setting are entries in control/locals and control/rcpthosts. I have to convince him that. Soo Aun "Timothy L. Mayo" wrote: > Is there an MX record in DNS for educast.com.sg?

vdomains: forwarders/pop3 accts with quota + accounting possible ?
Hi, I am currently setting up a new machine for my Webhosting(forwarding)-Service. Since I have heard a lot about qmail I would like to use it as MTA on this machine. I did read some docs on www.qmail.org but since I need some non-standart stuff I don't exactly know where to start. It would be nice if you could give me some advice in what direction I should head. I promise, I'll rtfm, but it is always good if someone with a lot of knowledge of a program tells you where to start and what to look at. Here's a list of what I need: - virtual domains support. (I'm planning on hosting over 2000 Domains on this machine. Yes, the number is correct - most of the domains are simple forwarders without webspace) - an easy way to make email-forwarders (you'll probably hit me but I like the sendmail virtusertable a lot - is there some equivalent for this in qmail ? I'm not talking about local aliases). - pop3 boxes that do not require one unix-user per popbox - quota-support for the pop3-boxes (seperate for every box) - accounting. I need to know which domain causes how much traffic per day (I'll probably need to write a little script for this myself but where should I integrate it into qmail ?) I currently have all the customer-data in a SQL-Database (forwarders/pop3 account for all domains etc. etc.), directly interfacing with it would be the best solution but generating configuration/forwarding files from it periodically would be ok also. How can I make QMail do all of the things above ? Please point me into the right direction :-) Thanks for you help, Jochen Tuchbreiter

For all mail inbound (i.e., via SMTP), just put the number of bytes (as in 2048000 for basically 2 megabyte limit) into /var/qmail/control/databytesChmod the file 644. AND/OR, 2. If you want to have some people be able to send huge mails (like up to 8MB), you can set MAXSIZE="812" either in your tcpserver control file on the line that will match their IP/IP range, like: 10.55.66.:allow,MAXSIZE="812",RELAYCLIENT="" The setting of MAXSIZE in the environment by tcpserver will override the /var/qmail/control/databytes setting, so you can use the databytes control file number as a catchall. I actually use a line in tcpserver's control file like :allow,MAXSIZE="1024000" to act as a catchall. -M Michael Brian Scher (MS683/MS3213) Anthropologist, Attorney, Policy Analyst Mainlining Internet Connectivity for Fun and Profit [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] Give me a compiler and a box to run it, and I can move the mail.

OT: Average Internet e-mail size
Hello List, I'm curious as to the average size of an Internet mail. I know this is very subjective, but would like to hear what people think is the average size. My calculations based on qmailanalog over a long run give me 64K, and that seems big. Looking at my inbox, the average seems more like 4K. Anyone?
Re: OT: Average Internet e-mail size
Found what seems to be an answer at http://www.groupcomputing.com/Issues/1998/98SeptOct/98SOp32_EmailCrisis/98sop32_emailcrisis.html Looks like around 25K is the average. - Eric Eric Dahnke escribió: > > Hello List, > > I'm curious as to the average size of an Internet mail.

OT: saturating a T1 with e-mail
Someone will scold me for this post, but would appreciate any thoughts: A T1 would be ~ 80% utilized passing 22,000msgs/hr if the average msg size was 23K. Thx

I would not bet on it. The average message size is not an indicator of network traffic. For example, if you pushed two messages over the line, one that's 2 gig and one that's 1 meg, the average would mean very little.

(average message size) * (number of messages per hour) - = peak seconds 1544 So, assuming your numbers are accurate, you could clear 22,000 queued messages of that size is 327.72 seconds of maximum throughput. That's only an average sustained throughput of about 9.2%. -- Todd A. Jacobs Network Systems Engineer

Rumor has it that Todd A.

That's only >an average sustained throughput of about 9.2%. Aahhh... not by my math. Remember, the 23K is *bytes*, whereas the 1544000 is *bits* per second. Assuming 8-bit bytes, the thruput would be 2621.76 seconds, or ~73% utilization, and if we were lucky enough to swing 7-bit bytes thru, it would give 2294.04 seconds, or 64% utilization. (I'm not sure how a T-1 router/gateway encodes bytes-to-bits...)

RE: OT: saturating a T1 with e-mail
Forgive me if the two posts from Eric were not related: saturating a T1: Todd presents a good formula, but this is not taking into account anything but the message size. As Stan mentions, email size is not a good indicator of total network traffic - even if you are only in the email business. Average email size: --- One of my systems sends out a text-only message twice a week. It is usually around 20k in size, and is (this week) 566 lines long, not including headers. This email is over four times our average message size. 64k average seems very large - of course when you factor in attachments, HTML- or RTF-formatted messages, the size can get up there. Looking at my inbox, however, which contains over 1200 emails, I have only 90 with attachments, and just ten or so that are not plain text. Unfortunately, the average size of an email is going to vary widely based on a number of factors which we can only begin to discuss before we realize that this thread gets out of control ;) <:) Lyndon
problem sending remote mail with tcpserver running
I've having problems with the local-remote delivery. There are no problems with local-local delivery, and I can do remote-local delivery (using fetchmail).

User masquerading on a server with multiple virtual domains
Does a user masquerading solution exist in which it is not necessary to add MAILHOST and MAILUSER environment variables for every user on a system hosting a half dozen virtual domains with hundreds of users? I have read FAQ sections 1.1 and 1.2: - 1.1. How do I set up host masquerading? All the users on this host, zippy.af.mil, are users on af.mil. When joe sends a message to fred, the message should say ``From: [EMAIL PROTECTED]'' and ``To: [EMAIL PROTECTED]'', without ``zippy'' anywhere. Answer: echo af.mil > /var/qmail/control/defaulthost; chmod 644 /var/qmail/control/defaulthost. 1.2. How do I set up user masquerading? I'd like my own From lines to show [EMAIL PROTECTED] rather than [EMAIL PROTECTED] Answer: Add MAILHOST=af.mil and MAILUSER=boss to your environment. To override From lines supplied by your MUA, add QMAILINJECT=f to your environment. - Neither FAQ offers a workable solution. 1.1 addresses the problem of masquerading when virtual domains are NOT being used. 1.2 addresses the problem at a microscopic level. However, the solution is not workable in an environment of hundreds of users and a half dozen virtual domains. It requires MAILHOST and MAILUSER environment variables for EVERY user. I am looking for a solution, similar in simplicity to 1.1, that works for virtual domains. - Bernie
