Re: qmail reliance on passwd file
Al Sparks wrote: Is there a way to get qmail to deliver email to an account that's not in /etc/passwd (or its shadow equivalent)? In other words, can I set up a separate database (e.g. MySQL) that qmail can access for account information? I note that qmail has /var/qmail/users/assign, but it references both UID's and GID's, which are maintained by /etc/passwd. I am setting up 2 clustered systems that will use shared storage (non NFS) to maintain each user's Maildir, and would rather not have to worry about keeping 2 separate system's passwd files in sync. qmail-ldap does this, and it contains native clustering code. www.nrg4u.com for details.

Instead I would like the branch mail server to realise that user4 is a local user and just deliver the mail to user4's local mail store. I suspect the easiest thing to do would be to get the qmail-ldap patches and install ldap. Keep the master LDAP database on the central server and run replica databases on each on the branch servers. I have a master LDAP server on it's own machine, because I use it for alot more than just email accounts. I have a replica LDAP server on all mail servers. LDAP replication is done real-time via SSL, only the master accepts modifications. Mail authentication is pointed to the local LDAP server on the mail server, so imap/pop passwords never fly in the clear. If you have failover LDAP and the local server dies for some reason, it will pick up a remote server and you will be in the clear unless you are on a vpn. I have asked Sam Varshavchik to implement SSL in Courier's authldap module. Each server would then be able to use LDAP to determine where the mail really belongs. The mail routing works very well to remote offices in US, Japan, and Germany. You also need Henning's dash-trick patch. This is required so that you can store aliases and pointers to ezmlm lists in LDAP, otherwise you have to use the same outgoing mail server for all offices and that is not too cool. I can provide details on how to do this if needed. I haven't used all the functionality that this would require, but I'm fairly certain that qmail-ldap has everything you'd need. And alot more.

I will put it into use if I get a requirement to send to at least 10,000 addresses. Using qmail-ldap and qmqp with a frontend master server and several slave servers, you can distribute the load among several servers very easily. For example, if you have 4 slave servers then use a unique mailhost attribute for each quarter of your subscriber base. The scalability of qmail-ldap is almost limitless, I think.

I have created three subdirectories with the same alias:qmail ownership: /var/qmail/alias/system - will contain system aliases such as postmaster, root, toor, manager, etc /var/qmail/alias/ezmlm - will contain ezmlm aliases /var/qmail/alias/normal - will contain everything else I want to use the users/assign file to assign the new locations to these .qmail-* files. The benefits of organizing my aliases into different directories are quite large to me, since I want to write some web apps for users to list and possibly manipulate aliases. Only certain users could change system aliases, and certain other users could change normal aliases. You get the point... My first test of just the system aliases got me into really big trouble on my test system. It took me about an hour to repair the damage caused. Read below to see what I did, and if you can tell me where I am going wrong. - copied the system aliases into their new location and made sure the permissions were correct. - wrote a users/assign file and ran qmail-newu. uid=7790(alias) gid=2107(qmail) /var/qmail/users/assign --- =bin:alias:7790:2107:/var/qmail/alias/system::: =daemon:alias:7790:2107:/var/qmail/alias/system::: =decode:alias:7790:2107:/var/qmail/alias/system::: =dumper:alias:7790:2107:/var/qmail/alias/system::: =games:alias:7790:2107:/var/qmail/alias/system::: =ingres:alias:7790:2107:/var/qmail/alias/system::: =mailer-daemon:alias:7790:2107:/var/qmail/alias/system::: =manager:alias:7790:2107:/var/qmail/alias/system::: =news:alias:7790:2107:/var/qmail/alias/system::: =nobody:alias:7790:2107:/var/qmail/alias/system::: =operator:alias:7790:2107:/var/qmail/alias/system::: =postmaster:alias:7790:2107:/var/qmail/alias/system::: =root:alias:7790:2107:/var/qmail/alias/system::: =system:alias:7790:2107:/var/qmail/alias/system::: =toor:alias:7790:2107:/var/qmail/alias/system::: =uucp:alias:7790:2107:/var/qmail/alias/system::: =uucp-default:alias:7790:2110:/var/qmail/alias/system::: . The result of this action what that file ownerships of my entire qmail install got changed to have an owner of alias, group of root. All of qmail/queue and qmail/bin were completely hosed. Qmail wouldn't even accept messages because it couldn't write to the queue. This took me about an hour of comparing between another functioning system to get all the file permissions and owners/groups correct again. How is qmail/bin/qmail-newu command changing the group/owner/permissions of my entire qmail installation? This is pretty unforgiving if a person new to this technique makes some mistake in the assign file, like I obviously have. I just couldn't believe that it could even do this. If somebody knows where I messed up, please reply to me and the list. Thanks, Mike

Re: Need Arguments for qmail
Jason Radford wrote: Recently switching from sendmail to qmail I have observed the difference in architecture between the two. The modularization of qmail appeals to me in both simplicity and elegance, and it's superiority was evident in my smtp benchmarking between the two MTAs. The only thing I miss from an admin standpoint is the readability of sendmail's logs vs. qmail/multilog. While I fully understand the justification of qmail's logging structure because of it's modularization, I am still left somewhat longing for a more readable logfile. Possibly over time I will develop a better skill for reading these logs, but for now that's my only concern since switching. There may be tools to aid in this, however out of the box this doesnt seem to be the cause. Hi, One thing that makes the logfile a bit easier to read is to change the time to human readable format like this: tail -f /var/log/qmail/current | tai64nlocal or this cat /var/log/qmail/current | tai64nlocal | less If you've installed the daemontools? package, then you should have tai64nlocal in /usr/local/bin. It would be nice to have a script that you could look at log files with, that would put the delivery in subsequent lines and strip out some of the garbage. That shouldn't be too hard to write for a good perl coder... Regards, Mike

Can someone please enlighten me, PLEASE !! svscan ``scans'' the directory that you give it for other directories. For each directory it finds, it spawns a supervise process that monitors the service defined in the run file found in that directory. If a supervise process (which monitors a service) dies for some odd reason it will restart another supervise process on that directory to keep the service running. That's all it does, plain and simple. Hi, I tried to use svscan for something other than qmail and couldn't get it to work. The process in question, slapd, wasn't producing specific log files, and svscan refused to start. It works just fine for me with qmail when I specify the log files for qmail. Mike

I am trying to find the similar functionality in qmail, if a patch or other method is available. The + symbol is needed, because this is what users have given out over time. Regards, Mike

Re: Backup Qmail Server
Michael Hornby wrote: I am running qmail on a server which will be going down shortly for upgrades. I have a unix machine running at my house (static IP address) that I would like to use as a "backup" server. I plan on changing the MX record for my domain to point to my home machine, and to have all the mail delivered there while the main server is down. Instead of having mail being sent to me bounce, it will go through via the backup server. My ultimate goal is to have my home server accept any mail that is being sent to any e-mail address being hosted on the main server, and to indefinitely try to forward it to the main server. This way, when the main server returns, it will receive all the mail it missed while it was down. All the e-mail will then continue to be stored on the main server, and users can login there to retrieve it. Does anyone have any ideas as to how I might implement this? Any help is greatly appreciated. Thanks in advance. The best way to upgrade your mail server is to install a forwarding sendmail on your firewall, then queue mail at the firewall until your new server is complete. Set the bounce timeout on the firewall to something like 5 days. I did this a week ago, and it took me about 30 hours for a large migration plus many mailing lists and domains... When you are happy, open the floodgates... I had about 4000 messages queued. Mike
Virtual Domain equivalent problem
Hi,
This is a very confusing thing I am trying to accomplish, but for
reasons outside of my control it must be done. I have a main domain name
of company..com in locals. I have a company.fi:alias-companyfi line in
virtualdomains. The alias file looks like this:
| forward ${DEFAULT}@company.com
All mail coming to company.fi should be a full equivalent to all
[EMAIL PROTECTED] addresses and mailalternateaddress in the ldap entries.
It is currently working fine, with one problem. One person needs to not
have his incoming mail rewritten to [EMAIL PROTECTED] I am controlling
the setting of his outgoing address to [EMAIL PROTECTED] with sendmail at
the firewall, but to not change the incoming address is what I need help
with. I tried to make an alias called .alias-companyfi-user and put
[EMAIL PROTECTED], then put mailalternateaddress: [EMAIL PROTECTED] in his
ldap entry, but the message looped and died.
Any ideas??
Thanks,
Mike

This exists on the old server. The new server will be laid out as follows: /var/qmail/maildirs/username/Maildir I would like to copy the inbox and all imap folders for each user to a staging area on the new server with a single directory for each user, such as: /var/qmail/staging/user1 that would contain files such as user1 (inbox from /var/spool/mail), and folders such as folder1 folder2 folder3 (from ~username/mail/). The conversion script would ideally go through every directory in /var/qmail/staging and create the maildir directory in /var/qmail/maildirs for each user. It would also take every file in mbox format in the users staging directory and put it into his maildir with the appropriate read or unread flag, as well as converting all files in the staging directory other than the inbox file into the same named folders in their maildirs. I would appreciate any advice from administrators who have sucessfully performed this same type of conversion. Please copy me personally if you reply. Thanks, Mike
