Re: [Dovecot] Switch from MySQL/CourierMail to MySQL/Dovecot
2012/12/7 Robert Moskowitz r...@htt-consult.com: Hello, new here. I am a Centos/Fedora user, and for the past 3 years have been running my mail server using Postfix/MySQL/CourierMail/Squirrelmail on Fedora. The current incantation of the tutorial is at: http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-mysql-and-squirrelmail-centos-6.2-x86_64 Well it is time to rebuild my mailserver; this time on Centos 6.3. My goal is to use supplied rpms, not to build my own (and rebuild everytime there is an important update). So I am pulling quotas which has been a pain anyway, and I am investigating using Dovecot in place of CourierMail.

There are a couple items that I have come to depend on in my current setup that are musts in anything new: Virtual user/domain That is, not only virtual domains, but also users defined by domain. So in the MySQL user table, the email value is set to user@domain. Thus a user can receive/send mail from multiple domains with the same addr and only those domains defined for the user in the user table. Obviously there is no coupling of Linux user accounts and email accounts. CourierMail is storing mail under /home/vmail/domain/user/... Encrypted passwords The passwords in the user table in MySQL are encrypted. This will be used to auth the user for POPing or IMAPing and sending their mail. I have encountered a few tutorials where it seems like passwords are stored in the clear? Anyway, not much else! Well as far as the user interface is concerned. Postfix with clamav and spamassassin and maybe one or two extras. And SquirrelMail for Webmail. A better gui than phpMyAdmin for maintaining the tables would be nice, but I don't have a lot of users, so it works well enough. Can someone point me to a tutorial best suited to my needs?

After I implemented it, a few weeks later, I noticed that some users were no longer getting their mail if they hadn't logged in during the past day. Postfix's mailq showed that hundreds of messages were backing up in the queue. I eventually tracked it down to leftover Kerberos credential cache files (/tmp/krb5cc_) sitting in /tmp on the mail server. The presence of expired credential files was preventing Postfix from delivering mail to those users' mail spools. If I delete the credential files manually, Postfix immediately delivers the queued emails. This is rather odd. Is krb5-authenticated NFS involved here, or does Postfix's delivery make any other use of Kerberos? The only other thing I can think of is that so many expired ccaches are accumulating that the user goes over their inode quota. Each user has one credential cache file in /tmp on the mail server after logging into Dovecot. We aren't using randomized names, so everything is in the standard format /tmp/krb5cc_uid. We do use KRB5 authenticated (and encrypted) NFS, but we don't deliver mail to home directories. Since all users are real users, and our office size is small, everyone has a mail spool directory on the mail server. Hmm. I don't have much experience with KrbNFS, and none at all on Linux, but the implementations I've seen seem to be terribly flaky about passing krb5 creds to the kernel. (What they ought to do is implement AFS' aklog and setpag; they're irritating, but at least they're well-understood...) In any case, it's likely that the delivery process looks in the user's home directory even if delivery is to a separate mail spool, unless you've taken steps to prevent this. For instance, Postfix's local(8) checks for ~/.forward by default, LDAs like procmail or maildrop look for similar per-user RC files, and Dovecot's LDA looks for (at least) ~/.dovecot.sieve. Is it possible that the NFS code returns a different error for 'no ccache present' vs 'ccache present but the creds have expired', such that Postfix will carry on delvering if it gets the first error but not the second? snip Well, I don't use RH (I use FreeBSD), but I use and would recommend Russ Allbery's pam_krb5.so, which may or may not be the same as the normal pam_krb5.so provided by your system. It has options to control whether and where ccaches are created; assuming Dovecot doesn't need krb5 creds (say, for NFS), you would probably be better off telling it not to create a permanent ccache at all. http://www.eyrie.org/~eagle/software/pam-krb5/ I haven't had to configure pam_krb5.so directly before (we use the Red Hat/Fedora configured default, pam_sss.so, which claims to be a one stop shop for LDAP/Kerberos/NIS,etc.), but it does seem to have more options. We certainly don't need credential caches to stick around for email users. All the mail spools are stored on locally mounted storage on the mail server. Where do users' private IMAP folders live? Are they in the mail spool as well, or are they in the user's home directory? Once a user has logged in Dovecot will change directory to their home directory (as returned by the userdb), so you may find you *do* need ccaches if they are on KrbNFS. This certainly does all sound related. What are the ccache files called: are they just /tmp/krb5cc_UID or is there a random portion as well? Are they being created with the correct permissions, and are there any security policies (SELinux or ACLs of some kind) set up which might interfere with their creation or destruction? No random portion (the only application we have configured with random ccache names is SSH), just the usual /tmp/krb5cc_uid. (I assume you're aware of the potential DoS here, given that /tmp is world-writable and sticky? I'm not sure if there's anything you can do about it if you're using KrbNFS, though.) Permissions appear correct, they belong to the appropriate user and group accounts. The SELinux permissions are set to: system_u:object_r:user_tmp_t:s0. This is different from the machine's credential cache (system_u:object_r:gssd_tmp_t:s0), but I've disabled and re-enabled SELinux during different parts of my testing and didn't notice any errors. I know nothing whatever about SELinux, but this might be relevant. gssd handles client-side credentials for NFS, so if it ends up unable to

It looks like I can change the forward_path, or set allow_mail_to_commands and allow_mail_to_files to disallow forwarding. As I said, we're a small office, so I doubt anyone will complain.

Re: [Dovecot] Maildir hardlinks with sieve
On 12/9/2012 10:12 PM, Benedetto Vassallo wrote: Def. Quota Benedetto Vassallo benedetto.vassa...@unipa.it: Hi all, As I had no response, I suppose there is no way to have maildir hardlinks work if I set up sieve. Is that correct? Apparently, not at this time. I think it should be fixable, but that will require some investigation. I won't have time for this until this weekend. Regards, Stephan.
Re: [Dovecot] Automatically Cleaning Kerberos Credential Cache Files
Ben Morrow writes:
In any case, it's likely that the delivery process looks in the user's
home directory even if delivery is to a separate mail spool, unless
you've taken steps to prevent this.
I can confirm this. I think the reason is that dovecot changes to the
user's home directory so that it has a place to dump core. This causes
problem for my setup since I user per-user NFS mounts, so a delivery to an
internal mailing list caused hundreds of NFS automounts.
I patched this behaviour out, but there is probably a more elegant solution
(unset MAIL_STORAGE_SERVICE_FLAG_ENABLE_CORE_DUMPS? How?).

[Dovecot] dovcot+offlineimap+gmail: INBOX empty, mail doubled
Hello
I have used for years
offlineimap-6.2.0
dovecot-imapd 1:1.2.9
in Kubuntu 10.04
Together with a imap server of my university. Yesterday we
switched to google, which I know, is not a real imap server.
I have 2 problems and the first I think has to do with
either an old version of offlineimap or a bad configuration file:
- All folders are downloaded+ Gmail[All Mail] so
doubling my mail.
- My INBOX folder is empty, however this is the only
folder for which offlinemap gives the following
warning:
Syncing INBOX: Gmail - MappedIMAP
WARNING: UID validity problem for folder INBOX (repo
UniLocal) (saved 1309334376; got 1355232397); skipping it
So maybe this is also a offlineimap fault.
In any case I have googled around and found out that I am not
the only person suffering this problem. I have attached my
configuration file in the hope that may be somebody could
give me a hint.
Thanks in advance
Uwe Brauer
