I did increase the value of
concurrencyremote so that it won't stay in the server too long, because the
default value is 60.
What are others opinions
on changing the value of concurrency??

Help! Cannot send email outside my own server!
Thank you to all for your guidance,
I started out
yesterday with 40,000+ in queue.
Now I am down to 542.
For the
benefit of other qmailtoaster fans...
This is my analysis of the
problem:
- I got a call from a customer that emails are not being sent to
yahoo, but within their company it works.
- I checked and indeed confirmed
this using another email server I also operate.
- I asked help here on the
qmail toaster mailing list
- I turned off the firewall, nope, that's not
it.
- Email receiving is fine.
- Clue from the Gabriel Lai Yong
Shern: qmailctl queue
- Found out I've got 40,000+ in the queue
-
They are mostle from a very large message board I host which holds 60,000+
members. The admin just sent a party invitation to everyone in the
board.
- Analysis from Jake Vickers regarding SPAM, I also checked with
the RBL evidence that I have an old insecure feedback form in php.
What
I did to help solve this problem:
- I fixed the feedback forms by updating
them to the latest ones with anti-spam
- I increased the
/var/qmail/control/concurrencyremote setting from 60 to 120
- I did:
qmailctl doqueue to speed up delivery
- I coordinated with the large
messageboard admin to fix his part and not send mail for a while
- Now
after more than 24 hours, I tweaked queuelifetime from 24 hours to 4 hours
just to help empty the queue.
- Now I am down to 500+ in the queue, I will
reset back the queuelifetime maybe to 12 hours.
What do you think
guys? Anything I missed?
Will update you on final resolution of this
problem.

Let's see. If I follow this, your main mail server got black
listed,
right? I did a check at DNSStuff.com, and see that you were
listed here:
http://psbl.surriel.com/listing?ip=209.11.243.202
http://www.spamcop.net/bl.shtml?209.11.243.202
Which
means that you are listed as a spammer. Since the second link is
SpamCop
(one that almost every one uses) that would explain why your
mail cannot
make it out of your domain. You need to find out who was
spamming, remove
them from your server, and on the SpamCop link I sent
they have
instructions on how to remove yourself from their list. This
is one of
the risks of hosting other people's websites/email. Hope you
charge them
enough to make up for the aggravation!
You could always swing all of your
email accounts to another server with
a different IP in the meantime.
But you will still need to investigate
why you were listed as a spammer,
or your new IP will just get
blacklisted, and on and on.
That will
also be why you have 3000+ emails in your queue. Most servers
will check
against SpamCop (or one of the many others), and since you're
listed as a
spammer, they drop connection on you. So your email sits in
the queue,
until your /var/qmail/control/queuelifetime is exceeded.
Sorry about
your bad luck, and hopefully that helps
some.
