Title: qmail and load balancers

Does anybody have a qmail system setup in a farm behind a RadWare WSD Pro+ load balancer using NAT outbound? If so, have you had any issues with large concurrency from the qmail server disrupting service on the RadWare systems?

When I let my qmail server loose, and have it send as much mail as it possibly can, it brings the load balancer to it's knees. Tech support has no idea what's wrong, and are presently trying to "recreate" the issue in their test environment. I'm just hoping somebody else has seen this problem before, maybe not even with a radware load balancer, but some other one?

Any input is appreciated.

Thanks,

Mark 



Hi there,

Does anyone know what each qmail loglevel does?
I've tried loglevel 0 and loglevel 5 and know the different. But I can't
see the different of loglevel 1-4.

Thanks in advance.

Assuming you're talking about syslog priority codes, "man splogger"
will tell you how it determines which codes to use.

I am running linux - 2.2.16.  I wonder if it is a bug with linux or a bug 
with the way QMails popup program runs on Linux?

I can see about trying it on one of my dialup banks and see what happens.  
Did you adjust the MTU as well, or just the MRU?

Hi all,

I'm having trouble getting forwarding to work. I have a
virtual domain for which I want all mail to use the aliases
database.

versions:
    qmail-1.03
    fastforward-0.51

settings:
    qmail/control/rcpthosts:
        tmpsj.org
    qmail/control/virtualdomains
        tmpsj.org:alias-virtuals

    qmail/alias/.qmail-virtuals-default
        | fastforward -d /etc/aliases.cdb
        &postmaster

When I test fastforward using the aliases database from the
command line:
    env [EMAIL PROTECTED] fastforward -n
/etc/aliases.cdb
it returns:
    from <original envelope sender>
    to <[EMAIL PROTECTED]>
which is correct;

however, sending mail to that address:
    mail  [EMAIL PROTECTED]
bounces returning with an error:
  sorry, no mailbox here by that name  #5.1.1

log file:
    /var/log/qmail/send/current
        ...starting delivery 1 ... to local
[EMAIL PROTECTED]
        delivery 1 ... failure: Sorry, no mailbox ...

I think the logfile tells me that the rule in
qmail/control/virtualdomains works and that the message is
making it into qmail-local.

This seems like it should be simple but I've been on this
for a couple of days now. I've RTFMed and been through lwq,
the faqs and the mail archives and can't figure out what I'm
missing.

Any suggestions would be very welcome : -)

Thanks,
Mike Wright






Hello.

Real-world scenario--that happened to one of my friends: a malicious
user sent huge amount of spam using e-mail address database stored on
a machine. This resulted in that machine's IP and domain name being
rejected by some big free e-mail service providers. Nothing unusual.
So the owner of the company sent an explanation and apologies to
postmasters and roots, but almost all of them bounced. This is
unusual.

My suggestion is: when you configure MTA to not accept e-mail from a
source, it should allow that source to send mail to at least root,
postmaster and hostmaster, or some other configurable accounts.

Please CC me as I'm not subscribed at the moment.
