What are the contents of /var/qmail/control/concurrencyincoming? What is the ownership and the permissions on that file? If you replace "$MAXSMTPD" above with 40 (or whatever) and restart that service, it may start working for you. You might also want to use "-H -R -l hostname" options if you think there are any DNS issues involved. Your use of -H and -p together above doesn't seem to make sense to me. They're contradictory.

Please see my later message to the list -- I'm sending this direct to save some time. This script is definitely LWQ. I think maybe /bin is not in your PATH for the script, or /var/qmail/control/concurrencyincoming is empty or '0'. If concurrencyincoming has '40' in it, try fully qualifying the path to 'cat' in the script -- like '/bin/cat' or '/usr/bin/cat', whichever is appropriate for your machine. If I'm correct, please feel free to quote any or all of this message to the list... I checked your earlier message, and qmail-showctl and this script seem to agree that 'concurrencyincoming' is the right file -- I can't count the number of times I couldn't figure out what was up when I got zero connections with '40' in /var/qmail/control/concurencyincoming ;) (Look closely at that filename) ;) HTH, -- GW

I haven't gotten a handle on qmail logging yet. Where are the log files stored? I look at /var/log/qmail and the files that are there contain these lines:
from /var/log/qmail/current
@40003b1518da292b19c4 status: local 0/10 remote 0/20
from /var/log/qmail/smtpd/current
@40003b1518da3494b75c tcpserver: status: 0/0
I don't think there is a load balancer problem with SMTP, as there is another mail server running sendmail right beside this one. It's just that it was setup by somebody else, who no longer works here, and I'm much more a fan of qmail than I am of sendmail, so we're moving forward with qmail installs now.
If I can provide any further information to you, please let me know.
Thanks,
Mark

This looks good (thanks for including it). What would help would be a copy of
the script you're using to start qmail-smtpd. tcpserver may be trying a
reverse lookup on your IP address and timing out, as well as some other DNS
lookups which happen. They can all be fixed with changes to your qmail-smtpd
script.
Also, are any error messages ending up in the qmail-smtpd log? Does outgoi

If it's a problem with your qmail-smtpd script, there should be errors in the log from the tcpserver instance for it. Another possibility, I suppose, is that the load balancer is somehow broken in regards to SMTP?

SMTP doesn't respond
Title: SMTP doesn't respond Hi, I've read up a little on this, but couldn't search the archives (maybe the server is down?) for any more information. Anyway, from my understanding, if the qmail server can't resolve it's DNS entry, it will have problems with SMTP, and I believe that to be the problem. However, I haven't been able to find a resolution for my situation. Here's how things are configured in my environment: The server is using a private ip address (192.168.x.x) behind a load balancer. The load balancer runs NAT so the server can send data out. The load balancer also contains a routable ip address, for which, all traffic passes back to the private ip. There is a DNS entry for the routable ip, but not for the private ip. The qmail server is setup with the same name as the DNS entry for the routable ip. As qmail runs on DNS entries, I would assume this would make everything ok. It doesn't. When I telnet to the localhost on port 25, I get a connection and it just sits there. No response, ever.
