I'm setting up a Postfix and Dovecot combination. What I want to do is have a user database that (1) is not running from some engine (so not LDAP or SQL or such) ... and (2) is completely disassociated from system users (e.g. most email users are not in /etc/passwd and most /etc/passwd users are not email users). Ideal would be a one-file solution, which can be managed by text editing or

Is there a tool equivalent to the system "passwd" command (or maybe "adduser" or "useradd") that can support a passwd-file by setting a password, encrypting it with the salted MD5 scheme? The system "passwd" command doesn't have an option to "do it to this alternate file instead of /etc/shadow".

I see no documents in the Dovecot documents wiki on how Dovecot features can be used in the fight against spam. One hit came up in a search, and it was about how to fight spam in the MoinMoin Wiki itself (e.g. TextCHAs and such). I already asked in another thread about removing message files at the search from a designated "learn-spam" folder. My next question would be how to

I have recipient_delimiter = + in main.cf (Postfix). But deliveries to dovecot/deliver are still being rejected. It appears that the full email is still in the envelope (e.g. phil+howard at example.com which I want to be delivered to phil at example.com). Is that how it's supposed to work and Dovecot just doesn't support this?

I suspect this is a user agent issue, given that Evolution is flaky in so many areas. When I deliver mail to a subfolder/subbox (e.g. the -m option in the deliver command), and Evolution doesn't know of it, yet, creating it fails, and Evolution still can't get to it. Doing things the other way around (create it in Evolution first, then deliver to it) works fine. Seems to be silliness to

I'm looking for an IMAP testing tool, suitable to use with Dovecot IMAP. It needs to support TLS, STARTTLS, and login/authentication. It needs to be able run from command line, shell scripts, and even do so under cron jobs (e.g. a way to supply the password to use w/o a terminal prompt). Typical interactive mail clients just don't cut it (even the text mode ones). One reason is I need

I have this in dovecot-postfix.conf: mail_location = maildir:/home/mail/dnamesum=%12MLd/dname=%Ld/unamesum=%12MLn/uname=%Ln/mail Yes, it is excessive, but that's just for testing. The pattern I really want is less clear for debugging. In postfix/main.cf I have: mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/dovecot-postfix.conf -a "${RECIPIENT}" I verified through

I'd like to have a variable substitute take the domain name part, lower case it, MD5 it, and take a 2-character substring of that. Would that be like %2MLd ? The documentation on the H hash modifier described reversing with R, but expresses it at %3RHu which seems to me like it would be reversing the hash result rather than the user string. I'm undecided about MD5 vs. hash, and could go

The Ubuntu package didn't create the directory for these. What ownership/permissions are needed for it? Does it need to be owned by the dovecot user?

I'd like to disable plaintext authentication (e.g. only allow authentication that does STARTTLS or connects on SSL/TLS only ports) only for certain (most) IP addresses. I want to exempt a few addresses (users coming over known VPNs). Fortunately, all this is coming in over a firewall (Sonicwall) in which I can NAT traffic by IP address to go to specific port numbers. So, if I can establish

Where can I find documentation on how to use the "dovecotpw" program that I was referred to? No man page. No wiki. Very little from "dovecotpw -h". What I need to do is generate the "passwd-file" contents with an MD5 scheme (the one equivalent to /etc/shadow is preferred).

The sample config file has: # User to use for the process. This user needs access to only user and # password databases, nothing else. Only shadow and pam authentication # requires roots, so use something else if possible. Note that passwd # authentication with BSDs internally accesses shadow files, which also # requires roots. Note that this user is NOT used to access mails. # That

I'm getting this message, which looks like Postfix is the one logging it, but I don't know where it comes from or which configuration it needs to be placed in. Anyone know what this means? May 26 13:13:28 eth0 postfix/pipe[13821]: warning: pipe flag `D' requires dovecot_destination_recipient_limit = 1

I have some emails that I think are in the Postfix delivery queue going to Dovecot, but didn't get mapped to their alias (because I didn't have all the alias entries in when they were queued). I'm wondering if this trick would work. I have the mail being delivered to /home/mail/%Ld/%Ln/mail and am wondering if I could make a symlink at /home/mail/example.com/foo -> bar and add a

I'm now putting together tools/documentation to manage/administer the mail server, including, of course, managing users. Round one will be command line tools. In order to avoid re-invention, I was looking around for existing tools. I really cannot find any. So it seems I will be developing them. The first will be the one to manage users in the passwd-file format. So I'm just asking

Is it possible with a simple config change to make address extensions, e.g. alice+sales at example.com, go into a folder, e.g. .INBOX.sales, and do so ONLY if that folder already exists (and just go into INBOX if it does not exist)?

Is there a feature or plugin to restrict access to IMAP/POP service by the domain name in reverse lookup? It would be even better if this restriction can exclude certain users (e.g. some users can access IMAP from certain networks but other users cannot). -- sHiFt HaPpEnS!

I'd like to run a script from cron that will scan certain mailboxes and move selected mail from one folder (usually INBOX) to another folder. The basic idea is to move previously detected spam based on headers prepended to the mail. Since I am not able to figure out how to get Postfix to invoke deliver with the -m option in these cases, and not in others, this is one idea I have come up with

I have a huge block of email that was misdelivered into the wrong folder. Moving it where it should be is not just all from one folder to being all of another folder. Basically, the index files need to be rebuilt. Looking in the wiki I cannot find how to do this. It all seems to be about installation, and no administrative tools. Or would it be just as simple as delete certain index files and

The sample provided config file (the one I started with by editing it) included the following text: # ------------------------------ WARNING ------------------------------- > > # If there's a file /etc/dovecot/dovecot-postfix.conf, which is part of > # dovecot-postfix package, it will be used instead of dovecot.conf. > > # Keep in mind that, if that file exist, none of the
