LDA input validation
by Stéphane Cottin 24 Jan '15

24 Jan '15

Hi, I'm using qmail + dspam + dovecot-lda. A typical .qmail file : | /usr/bin/dspam --client --deliver=stdout --user "$EXT@$USER" | /usr/bin/preline -f /usr/lib/dovecot/dovecot-lda -d "$EXT@$USER" -a "$EXT@$USER" -m "$EXT2" When dspam segfault or is killed, preline receive an empty content and only pass to dovecot-lda two headers ( Return-Path and Delivered-To ). Then dovecot-lda delivers successfully and the original message contents are lost. Should dovecot-lda returns an error in such conditions ( invalid contents ) ? Qmail will keep it in the queue and retry delivery later. Stéphane

Mailbox corruption (dovecot 2.2.13, Debian 8)
by Santiago Vila 23 Jan '15

23 Jan '15

Hello. The attached mbox folder becomes corrupted in the server when being retrieved by fetchmail using the --folder option. This happens on a system running Debian jessie (i.e. dovecot 2.2.13) using the default configuration. I've reported this to Debian here: https://bugs.debian.org/776094 but I thought it would be good to post it here as well in case it is still a bug in the latest version (well, if it's not anymore a bug in the latest version, a patch against 2.2.13 will surely help the Debian maintainer in either case). Thanks.

sieve filter not working
by Michael Williamson 23 Jan '15

23 Jan '15

Hi, I have a question. I have dovecot 2.0.9 running on a CentOS 6.6 email server for a small department, ~15 users. amavis and postfix are also enabled. It appears that amavis invokes spamassassin, which tags incoming spam email. All email is then put into users local inbox directory, regardless of spam tag X-Spam_Flag value of YES or NO. I want instead to redirect spam to a special directory. I put a sieve filter in users home directory, "/home/user/.dovecot.sieve": require ["fileinto"]; # Move spam to spam folder if header :contains "X-Spam-Flag" ["YES"] { fileinto "Maildir/.SPAM"; stop; } I try different target directory for fileinto, ".SPAM", "/home/user/Maildir/.SPAM/cur", etc.. I know that those directories exist. The configure file "/etc/dovecot/dovecot.conf" is in original state. I changed one line in configure file "/etc/dovecot/conf.d/15-lda.conf": protocol lda { # Space separated list of plugins to load (default is global mail_plugins). mail_plugins = sieve $mail_plugins } I changed one line in configure file "/etc/dovecot/conf.d/20-lmtp.conf": protocol lmtp { # Space separated list of plugins to load (default is global mail_plugins). mail_plugins = sieve $mail_plugins } The configure file "/etc/dovecot/conf.d/90-sieve.conf" is unchanged, the relevant part is: plugin { # The path to the user's main active script. sieve = ~/.dovecot.sieve ... I restarted dovecot. I checked that it is running. The configuration command # doveconf -a output is attached. It is not working. How do I diagnose the problem? Thanks, -Mike

Client shows null Sender & date
by John Hendrich 23 Jan '15

23 Jan '15

I'm using Postfix and Dovecot 2.0.19 and Virtual domains & users (mysql). Incoming mail is handled by Postfix and then handed off to Dovecot LMTP for delivery. However, the Sender and Date are essentially null when viewing the email with either the POP3 or IMAP client. The logs (below) show this. I changed the sender and recipient addresses for privacy. Jan 23 08:41:48 klsrv postfix/smtpd[10836]: 1F907F00276: client=unknown[10.0.0.19] Jan 23 08:42:07 klsrv postfix/cleanup[10842]: 1F907F00276: message-id=<> Jan 23 08:42:07 klsrv postfix/qmgr[4889]: 1F907F00276: from=<sender(a)example.com>, size=217, nrcpt=1 (queue active) Jan 23 08:42:07 klsrv dovecot: lmtp(10845): Connect from local Jan 23 08:42:07 klsrv dovecot: lmtp(10845, recipient(a)example.net) wvU2Gq9PwlRdKgAAjuDoqw: subject=test to client: from=: msgid=unspecified: status=saved mail to INBOX: Jan 23 08:42:07 klsrv postfix/lmtp[10844]: 1F907F00276: to=<recipient(a)example.net>, relay=klsrv.airhop.net[private/dovecot-lmtp], delay=28, delays=28/0.01/0.01/0.01, dsn=2.0.0, status=sent (250 2.0.0 <recipient(a)example.net> wvU2Gq9PwlRdKgAAjuDoqw Saved) Jan 23 08:42:07 klsrv dovecot: lmtp(10845): Disconnect from local: Client quit (in reset) Jan 23 08:42:07 klsrv postfix/qmgr[4889]: 1F907F00276: removed You can see that Postfix accepts the incoming mail (from sender(a)example.com) and then the message is handed to Dovecot LMTP. But the from=: should be "from=sender(a)example.com:". Postfix / qmgr has the sender listed (from=<sender(a)example.com>) but no sender (from=) is seen in LMTP log output. My LMTP is setup to use UNIX sockets, not the INET socket. Any help is appreciated.

Postfix Dovecot LDAP setup
by Leander Schäfer 22 Jan '15

22 Jan '15

[EDIT]: Sorry about the second mail. ignore the first one - it had try & and error mistakes in. Problem is still the very same as explaned below. Thanks a lot. Hi, since days I'm trying to substitude my SQL based Postfix/Dovecot mail server by a LDAP based setup. Everything seems to go smooth so far - thanks to the many how to and Dovecot wiki. Unfortunately I'm struggeling, since I have to create individual a LDAP schema which suits the currently used LDAP structure. The current tructure looks like this: => dc=MyDomain,dc=TLD ==> ou=People ===> uid=User-1 ====> ou=mail ===> uid=User-2 ====> ou=mail ... and so on ... Within ou=mail should be the individual mail account(s) information of a user. So in the end I want to add a(nother) mail account by something like this: cat << EOF > ./newUser.ldif dn: mailAddress=Test(a)Domain.TLD,ou=mail,uid=User-1,ou=people,dc=MyDomain,dc=TLD objectclass: top objectclass: mailAccount mailAddress: Test(a)Domain.TLD MailPassword: {SSHA}SomePassword MailAccountStatus: active [...] EOF Therefore I setup a LDAP schema like the following, but it seems to ignore the attributes "MailPassword" and "noMailAccountStatus". Why? I don't understand what I'm missing here on my objectclass? ;/ # ====================== LDAP schema ======================= # # # OID Macros (10001 should be IANA-registered) # objectidentifier nameSpace 1.3.6.1.4.1.10001 objectidentifier mail nameSpace:1 objectidentifier objectClassAccount mail:1 objectidentifier objectClassAccountInfo mail:2 # # Attributes: objectClass[NAME]:1.[SERIAL] # attributetype ( objectClassAccount:1.1 NAME 'mailAddress' DESC 'The hosted mail addresses' EQUALITY caseIgnoreIA5Match SUBSTR caseIgnoreIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26{256} SINGLE-VALUE ) attributetype ( objectClassAccount:1.2 NAME 'MailPassword' DESC 'The hosted mail password' EQUALITY octetStringMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.40{128} ) attributetype ( objectClassAccount:1.3 NAME 'MailAccountStatus' DESC 'The status of a user account: active, noaccess, disabled, deleted' EQUALITY caseIgnoreIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE ) [...] # # Objects: objectClass[NAME]:2.[SERIAL] # objectclass ( objectClassAccount:2.1 NAME 'mailAccount' SUP ( top ) STRUCTURAL DESC 'Mail account' MUST ( mailAddress ) MAY ( MailPassword $ MailAccountStatus ) ) # ====================================================== # Thanks Best Regards, Leander
