All I know is that I YUM updated my FC4 system and the problem went away. I didn't care to look to see what component was actually at fault. I don't really care. For me it must have been a kernel or related package because when I down graded to an older kernel, the problem also went away. It was only with the most recent kernel at the time and possibly whatever it drags in that the problem manifested itself. After another kernel upgrade, the problem disappeared. Regardless, it seems like no user-facing tools should ever segfault. Agreed. But by the same logic, NOTHING should ever fail. If by user facing tools, you mean a vpopmail component, you must remember that vpopmail like most applications uses libraries of object modules for a good portion of its functionality. Those libraries sometimes evolve to contain a bug of some sort, and then vpopmail inherits the problem. -- Bill Gradwohl

[vchkpw] Segmentation Fault with new Kernel
I've got an older vpopmail (5.4.10) that now seg faults on vadduser.
This started after a kernel upgrade on Fedora Core 4. I recompiled the
application, thinking it was a library issue but that did not solve the
problem.
strace shows :
stat64(/home/vpopmail/domains/private.ycc/1/qqq, {st_mode=S_IFDIR|
0750, st_size=4096, ...}) = 0
open(/home/vpopmail/domains/private.ycc/1/qqq, O_RDONLY|O_NONBLOCK|
O_LARGEFILE|O_DIRECTORY) = 3
fstat64(3, {st_mode=S_IFDIR|0750, st_size=4096, ...}) = 0
fcntl64(3, F_SETFD, FD_CLOEXEC) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
Anyone know what changed?
The archives mention this problem, but I could see no resolution or
reasons given for the failure.

When I want a new box, its got a newer O/S, newer versions of vpopmail, newer qmail (patches), newer clamav, etc, and trying to tar dump an old environment into a new one isn't trivial. Therefore, I prefer to create the commands needed to recreate the environment from scratch which assumes I've had a catastrophic failure, and was forced to create a new box up to the point where I want to add domains and users. Then the info from the scripts above comes into play. We rsync the entire box to a spare drive in a different box every night. From that spare drive, we can extract whatever info we want even after the real box has died, got stolen (it happened), whatever.

[vchkpw] Archiving mail
I know this subject has been touched on several times on this and the qmail list, but I have yet to see a comprehensive resolution, so please bear with me. Texas courts are now moving legal documents via email between the respective attorney's offices, and attorneys are asking for a way to archive everything in and out of a virtual domain as a permanent record. The Subject: contains a case number. SEC regulations as well as Sarbanes-Oxley (SOX) require those affected by these rules to archive all inbound and outbound mail. qmail has a rudimentary facility to do this with a patch to the extra.h file. It doesn't archive a duplicate of the mail, but simply ads an artificial CC to it to force the rest of the system to send a modified copy of the email to a specific location. That may or may not satisfy SEC or SOX requirements - I don't know. One can argue that what the archive holds was never sent to the server due to the CC modification. When vpopmail is added to the mix, the promise of the extra.h patch looses its usefulness as what most sites want/need is an archive per virtual domain or even per user, not for the box as a whole. Its been mentioned that maildrop can archive mail, but I believe it can only do this for mail that eventually gets analyzed via a .qmail file. There is no mechanism for mail sent out to be archived via maildrop. Please correct me if I'm wrong. Is there a comprehensive way to archive mail EXACTLY AS IT WAS SENT, either in to the domain or out from the domain, IN A VPOPMAIL ENVIRONMENT, on at least a virtual domain level? If so, how? Note - recordio is not a solution. Adding extra delivery instructions in the .qmail file for a user is less than satisfactory especially since it will only archive a facsimile of the mail and then only for mail send to the domain, completely missing any mail originating on the domain destined for the outside world. -- Bill Gradwohl [EMAIL PROTECTED] http://www.ycc.com

[vchkpw] Where are your .qmail files
In a recent qmail list posting, as supplemental information for his real problem, a vpopmail user offered his observation that all his .qmail files were located under his userid directories. i.e. /home/vpopmail/domains/xyz.com/moe/.qmail, .../larry/.qmail, .../curly/.qmail. As this was on a qmail list, it was inappropriate for me to investigate this further there. My .qmail files are called .qmail-moe, .qmail-larry, and .qmail-curly and reside at the domain level (xyz.com in my example) - not below the individual user directories. I tried to put them under those user directories, but they appeared to be ignored. Where are your .qmail files located and what are they called?

Re: [vchkpw] Log all email per domain antivirus that notifies recipients
Thank you to all that replied. I'll take a look at qmail-scanner, simscan and QMVC as suggested. In case someone follows this thread in the future, I want to mention that I used the technique referenced via http://cr.yp.to/qmail/faq/admin.html#copies successfully for years. Then I decided to implement virtual domains via vpopmail, and couldn't make it work in the virtual environment, even to a single log for all domains. I don't recall all the tests I ran, but I eventually gave up trying to make it work. There's no logic that I can find to make it support a log per virtual domain in any case. Because the sender of the infected mails is the Texas Court system, normal logic rules don't apply. If the courts have a record of sending a particular email, they record it as successfully contacting the attorneys for the case. If the receiving MTA trashes that email due to a virus, and some court date is missed or document isn't filed as a result, the courts are blameless. Therefore, only something that warns the recipient (clerk @ attorney's office) is of any value, and that warning MUST at a minimum contain the Subject: line as that's the only identifier for what case is involved. If there were a way of eliminating only that portion of the email payload that was infected, and allowing the remainder to hit the recipients inbox, that would be the best solution. Rebuilding an email of only the clean portions isn't something that exists as far as I'm aware. As an aside, how would you like being on the receiving end of this set up? Your case is before the courts, and a virus or anything else disrupts the flow of email. You are, in effect, guilty because something didn't happen as it should have because the courts have declared that email is a guaranteed delivery mechanism. This system is coming to your state, as Texas was used as the test site. This idea is so bad that foreign governments are also likely to pick it up. -- Bill Gradwohl [EMAIL PROTECTED] http://www.ycc.com SPAMstomper Protected email
[vchkpw] Log all email per domain antivirus that notifies recipients
Two issues: 1) Using qmail vpopmail, what methods are available to log all inbound and outbound email PER VIRTUAL DOMAIN? 2) We also need a way to notify the recipient of an email that contained a virus that the infected email was destroyed, and that it came from [EMAIL PROTECTED] with a subject line of whatever it was. We have a law firm that wants to record all their communications in both directions. We are capturing inbound emails by appending [EMAIL PROTECTED] to the end of everyones .qmail file. What's missing is a way to capture the outbound emails. Texas courts are currently in the process of requiring attorneys to use email to file and update their cases. They are using email as though it was a guaranteed delivery mechanism even though we all know it isn't. This pilot project is expected to go nationwide soon. When the courts send out an email containing a virus (they use Windows boxes), the normal thing for a receiving MTA's virus checker to do is silently throw that email away and not notify anyone. In this case however, that email has legal ramifications so that either we have to let the infected email pass thru the server, extract only the infected portion of the email leaving the rest intact (no idea how to do that), or throw it away but notify the recipient of what was done. The subject line of these emails contains a case number that could be used as follow up by the receiving clerk at the law firm. We currently use qscanq to call clamav for the heavy lifting, but that approach doesn't offer a way to notify anyone of what happened to an infected email - at least not any way I know of. We'd like solutions that have per virtual domain granularity so other domains on the box don't have to do things the same way. Suggestions? -- Bill Gradwohl [EMAIL PROTECTED] http://www.ycc.com
[vchkpw] Archive all emails
I've checked the archives, but searching on archive or log is fruitless. Generic qmail offers a way to archive all emails to a specific user via a fix to the extra.h file prior to compiling. For years, I've patched it to route mail to user qmaillog and its worked well. Every time I try to implement this along with vpopmail, I get hundreds of vdelivermail processes launched and nothing ends up in domains/whatever.com/qmaillog's Maildir. When I recompile qmail with a default extra.h everything works as expected, but there's no archiving. What I'm really after is an archive per virtual domain, not an archive for qmail as a whole. At this point however, since I can't get any form of archiving to work, I'd implement whatever I can get to function. Is there a known technique for archiving per virtual domain? Any help would be appreciated. Thank You. -- Bill Gradwohl YCC (817) 224-9400 x211 www.ycc.com

What files were left behind, and where did they come from? I created a testuser for testdomain.com and noted that the user ended up in /home/vpopmail/domains/testdomain.com/testuser as expected. I then manually created a .qmail-testuser file at the domain level /home/vpopmail/domains/mydomain.com, and ran some tests and that .qmail file did get used. I put it at the domain location instead of inside the users directory because that's what a script I saw did. Then I vdeluser deleted the testuser and the .qmail-testuser file was still there. Maybe I've got the .qmail file in the wrong place. ??? Should a user specific .qmail file be inside the domain directory or inside the users directory? If it's inside the users directory, then vdeluser will nuke it. If it has to be at the domain level, then it would be nice for vdeluser to nuke it since there isn't any other possible use for that file. -- Bill Gradwohl YCC (817) 224-9400 x211 www.ycc.com
