No, turns out it was gpatch vs patch (SUN C Compiler patch came first in path). By tweak I meant where I was or where I put the patch. I had made a change to my .profile for something else and mispeeeeled local in the PATH so it found the /usr/bin/patch first. Thx guys. Back to lurk mode. :)

Sorry about making people dig for the URL; I pointed to the wrong message in that thread by accident. The actual patch URL is http://pyropus.ca./software/misc/qmail-1.03-domainbindings-1.2.patch . If you get "what file?" errors from `patch`, you probably gave it the wrong -p option. My patches should apply with `-p1` if you're in the qmail source directory. Charles

Re: Spam Handling

Michael Puckett — 2008-11-28T07:26:16

Already done. I installed the RCPTCHECK which allows me to call an external program to verify the RCPT during the SMTP conversation. I have a file which contains the addresses that I want to reject which is checked against. Actually, this patch is quite powerful and can be as complex as you like for determining what you wish to do on a per recipient basis. The good thing is that I am able to terminate the SMTP connection prior to the transfer of the message body which conserves bandwidth on my (slow) ISP link. So far, it is working great. It doesn't deal with SPAM which comes directly to my own mailbox, but for those who are trolling the other "standard" users that you may (or may not) wish to have enabled it works great. -mikep

Make sure that you have enough RAM to handle X concurrent qmail-smtpd without crashing your server. Andy

Re: MX retry

Andy Bradford — 2008-11-28T03:08:05

Thus said Mark Walker on Sun, 23 Nov 2008 03:36:40 PST: This is absurd. Why would they announce an MX with highest priority that isn't responding correctly? They have some serious issues. The point of an MX record and ``distance'' is to provide to the remote MTA the preferred server. Only if that preferred server is down will qmail attempt delivery to a lower priority, so they should really fix their primary server. If they want MTAs to send email to their lower priority servers, then they should adjust the priorities appropriately. This is not an epidemic. The problem is not qmail's (although some will argue that qmail should behave more like X MTA). Andy

Hi, Does it exists an alternative to control/badmailfrom that would be in some hash format. Preferably that would avoid patching the source. I'll have a look at that. Thanks, Olivier

Re: Multiple virtual domains with different IP address

Kyle Wheeler — 2008-11-27T20:55:48

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I understand what you're aiming for, but you're misunderstanding the "solutions". Normally, you cannot specify what IP address qmail will use for its outbound email, no matter how many installations you have. Patch 1 (you're quoting *my* website to describe it) allows you to specify ONE address for all outgoing emails. If you want different (virtual) domains to use different addresses, each domain will need its own installation of qmail. Patch 2 allows you to use a single qmail installation, but has the problem that in many cases it cannot figure out which IP address to use (as it says, this happens when "qmail-remote is not able to determine the domain name or the domain name is not a local domain which can happen in case of forwarding the default is being used." In other words, if foo< at >notyours.com sends a message to bar< at >yourdomain.com and if bar< at >yourdomain.com is forwarded to another address (e.g. bar< at >somewhereelse.com), then that patch cannot

Jose — 2008-11-27T17:59:58

Thank you for the assistance. I am including below links and text from the two patches (to help others encountering the same problem) and what I think is the best solution for low volume virtual domains. The requirement is: - virtual domains, each with a separate outgoing ip. Option 2 (patch 1) seems the best solution as it doesn't require multiple installs and it seems a simple patch. Patch2 handles any domain that may be relayed rather than restricting the solution to a set of domains defined in a configuration file (like in patch 1). My main argument against multiple installs is that increases installation and maintenance work when all the domains are low volume please let me know if I misunderstood the different options. thanks and regards jose .............................................................................................................. 1.

Hi, I don't know whether it is in partitcular useful to suck in 500k addresses per qmail-smptd call (i doubt it; and it is certainly neither effective nor efficient) but there is no artificial limit in qmail. However, if you use softlimits, that needs tuneing and may be the reason for this behavior. regards. --eh. --On Donnerstag, 27. November 2008 10:35 +0700 on< at >cs.ait.ac.th wrote:

Hi, I am very new to qmail and trying to help a friend debug his server. We tried to implement the black list from http://www.sa-blacklist.stearns.org/sa-blacklist/, that consists of over 500,000 entries to be added to /var/qmail/control/badmailfrom. 1) I am using the full list of 500,000 enties and restart qmail. If I try to connect to TCP port 25, qmail responds with a "421 unable to read controls" error. qmail-showctl will display the full list of 500,000 rejected mail from addresses. 2) If I use any sublist of about 40,000 entries, qmail works fine, so I assume that the entries are valid. 3) If I use any sublist of about 80,000 entries, same error 421. Is there a limitation in the size of the badmailfrom control file? Is there a way to tune that limit?
