[Dovecot] 2.0: deliver run from multiple uids and configuration files
I'm trying to run deliver from exim transport in a way that it doesn't need to query userdb AND doesn't need to read configuration files. The problem is that config files are readable for root only and if I run deliver with multiple UIDs then I would have to allow reading config files for everyone. Of course that's not a option because configs contain database passwords and such stuff. I wonder if it is possible to avoid reading config files by deliver? The only solution I see it to run deliver via sudo which doesn't look nice. -- Arkadiusz MiśkiewiczPLD/Linux Team arekm / maven.plhttp://ftp.pld-linux.org/
[Dovecot] permission recomendation for dovecot configuration files and binaries
I'm trying to figure out which permissions will be the best to handle most of tasks (for use in rpm package) for configuration files. Basically /etc/dovecot/ dir /etc/dovecot/* files /etc/dovecot/conf.d/ dir /etc/dovecot/conf.d/files dovecot binaries, deliver mainly For example deliver needs to read configuration files and needs to write into destination. Doesn't seem to be sane to allow MTA user read dovecot configs but that is requires for deliver to work etc. Are there any sane/tested recommendations that would fit most situations (remember, that's going to be rpm package default config) ? -- Arkadiusz MiśkiewiczPLD/Linux Team arekm / maven.plhttp://ftp.pld-linux.org/

[Dovecot] 1.2.10 and questions
Hi, 1) Why dovecot -n doesn't display default values? At least it didn't display mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 10 if I had set ONLY mail_max_userip_connections (to be =10) 2) Maximum number of connections from user+IP exceeded (mail_max_userip_connections): Could it be enhanced to actually log what the limit was at that time? -- Arkadiusz MiśkiewiczPLD/Linux Team arekm / maven.plhttp://ftp.pld-linux.org/

[Dovecot] crypt() failure is possible
dovecot 1.1.15 in src/auth/password-scheme.c
contains:
static bool
crypt_verify(const char *plaintext, const char *user ATTR_UNUSED,
const unsigned char *raw_password, size_t size)
{
const char *password;
if (size == 0) {
/* the default mycrypt() handler would return match */
return FALSE;
}
password = t_strndup(raw_password, size);
return strcmp(mycrypt(plaintext, password), password) == 0;
}
but according to man page crypt() can fail and NULL is returned then. On other
hand glibc info page is silent about such failure.
The thing is that I'm seeing crypt() failure here with new glibc 2.10.1 built
with nss backend for crypt(), so it would be good to handle such case.
(crypt failure was due to improper nss packaging but it could also happen if
somehow nss file becomes corrupted)

You can configure Exim to write ,W=vsize even without use_crlf. Configuring

within maildir_tag setting of exim works especially well for me.

I have mails delivered via exim with this rule:

cat new/1225046769.H367740P9241.mbox2.agnat.pl,S=1377,W=1413 | wc -l

I'm also wondering that.

cat new/1225046769.H367740P9241.mbox2,S=1377,W=1413 | wc -l
37
so 1377 + 37 + 3 = 1417 which doesn't match 1413.
But this doesn't seem correct either. File size + linecount should be
the same as W. Is the file size really 1377 bytes?
It is:
-rw-rw 1 mail mail 1377 2008-10-26 19:46
new/1225046769.H367740P9241.mbox2,S=1377,W=1413
Also adding 3 is weird. Exim documentation says The blank line that separates
the message header from the body is not counted. so it's only 1 line, not 3.
For example a file that Dovecot has created:
% wc -cl 1224418671.M66880P13668.hurina,W=2087
56 2031 1224418671.M66880P13668.hurina,W=2087

Ok, it also says that $message_linecount can be incremented when exim adds
some headers. That's probably what +3 was trying to do (1+ some 2 headers?).
Unfortunately it looks that W=${eval:$message_size + $message_linecount + 3}

You're most likely using dirsize quota backend.

Hm, http://wiki.dovecot.org/POP3Server doesn't mention anything about cache not being created. It even says that dovecot.index.cache is actually used and updated. Is it used (including updates) when and only when if it's created earlier by imap? -- Arkadiusz MiśkiewiczPLD/Linux Team arekm / maven.plhttp://ftp.pld-linux.org/
[Dovecot] delivery and quota question
Hi,
I'm considering using delivery for delivering emails. The question is about
quota. Does delivery check quota for single maildir or for entire collection
of user folders?
Example:
/var/mail/user/{new,cur,tmp}
/var/mail/user/.Some_Folder/{new,cur,tmp}
/var/mail/user/.Some_Other_Folder/{new,cur,tmp}
Can I somehow get deliver checking size for all these folders? I need quota
per user not per folder.

Does it merge all of them into one virtual POP3 INBOX? tpop3d has a option maildir-recursion: yes that makes it merge all subfolders in one virtual inbox. Very nice and usefull thing. With additional maildir-ignore-folders: Spam Trash trash Sent sent-mail POP3-Invisible and proper MTA settings spams goes to POP3-Spam subfolder but user can change things and MTA will start deliver to Spam folder (which is invisible via pop3) so user simply chooses whether he wants or not to see spam emails etc. User can still use imap based webmail or connect to imap and see other, pop3-ignored folders. With Dovecot the POP3 shows only the one real INBOX's contents. Some day in future there will be support for virtual folders, and if you need POP3 to show more than just the real INBOX then you can create a virtual INBOX. Uh, recursive subfolders is basic functionality that I unfortunately need :-\ I'll look into sources to see how much work is needed then. -- Arkadiusz MiśkiewiczPLD/Linux Team arekm / maven.plhttp://ftp.pld-linux.org/
