How to limit Apple Mail (desktop)?
by Rupert Gallagher 02 Nov '17

02 Nov '17

By default, Apple Mail downloads all e-mails from server's account. Previous versions of this client allowed to opt-out. The latest two versions? however, only allow to opt-out from downloading the attachments. The stress on the server is unbearable. We cannot ask users to be considerate: this is the default behaviour of Apple Mail. We need a server-side solution to the problem. Please share your ideas.

LDAP authentication and shadowExpire
by Mantas Gegužis 02 Nov '17

02 Nov '17

Hi, I am trying to configure Dovecot (2.2.27) with LDAP passdb, specifically with authentication binds (https://wiki.dovecot.org/AuthDatabase/LDAP/AuthBinds). Atribute shadowExpire has a unix time stamp value. Is there a way to write pass_filter like shadowExpire<ToDay? Or maybe there is better way to implement password expiration in Dovecot? -- Pagarbiai Mantas Gegužis VU Informacinių technologijų taikymo centras

We cannot ask users to be > considerate: this is the default behaviour of Apple Mail. (I'm coming into this thread late.) I'm having a hard time visualizing the cause of your problem. Most big messages have the bulk of their data as attachments (which you state the mail reader can defer downloading). Also, readers usually cache local copies, so they're downloaded once. So what the composition of all this traffic? Are you saying the mail client is ultra dumb and repeatedly downloading entire messages, read and unread, attachment and all (i.e. you're truly bandwidth limited?) Do your users typically have many concurrent readers for the same mailbox? What kind of session numbers are you supporting? 100s? 1000s? 10K+? Your data outflow has an incoming counterpart: if you're having a hard time serving it out, is your MTA also having a hard time with the incoming volume? Can it simply be the case you've underscaled your remote mail service? Joseph Tam <jtam.home(a)gmail.com>

All over sudden dovecot thinks FS is read only

Hi list I have to dovecot instances running which host my mailboxes on Centos7 dovecot.x86_64 1:2.2.26.0-2.el7.centos installed dovecot-debuginfo.x86_64 1:2.2.26.0-2.el7.centos installed dovecot-mysql.x86_64 1:2.2.26.0-2.el7.centos installed dovecot-pigeonhole.x86_64 1:2.2.26.0-2.el7.centos installed all over sudden both dovecot "think" that the mailbox filesystem is read only and fill the logs with Oct 28 11:39:50 mbox1 dovecot: lmtp(tobster(a)brain-force.ch): Error: ssY/MGZQ9FnoLgAAC4IaJw:2: sieve: failed to open logfile (LOGGING TO STDERR): open(/home/vmail/brain-force.ch/tobster/.dovecot.sieve.log) failed: Read-only file system But a test at cli shows that I can write to the location $ echo "test" >/home/vmail/brain-force.ch/tobster/.dovecot.test $ cat /home/vmail/brain-force.ch/tobster/.dovecot.test test $ echo "test1" >/home/vmail/brain-force.ch/tobster/.dovecot.test $ cat /home/vmail/brain-force.ch/tobster/.dovecot.test test1 Mounts show that the FS should be rw /dev/vda2 / ext4 rw,relatime,data=ordered 0 0 I restarted dovecot several time already.

Pigeonhole vacation and envelope extension recipient addresses
by David Zambonini 31 Oct '17

31 Oct '17

I have a situation where my LMTP RCPT TO: goes to a mailbox user account that does not reflect either the final (through aliasing) or envelope email address. SMTP RCPT TO: (envelope-local-part@envelope-domain) Final Recipient: (final-local-part@final-domain) LMTP RCPT TO: (mailbox-local-part@mailbox-domain) I'd like to use the final recipient as the vacation address, but also have the envelope recipient address used in place of the LTMP RCPT TO for the envelope extension. At the moment it looks like I can set one or the other? Let's say I add an x-final-to and x-envelope-to header to the email headers before delivering via LMTP. Then, setting: sieve_vacation_use_original_recipient = yes lda_original_recipient_header = x-final-to will get the vacation replies coming from where I'd like, but the envelope extension will not reflect the original SMTP envelope to. Conversely, setting: lda_original_recipient_header = x-envelope-to might get the envelope extension working correctly, but will not give vacation replies from where I'd like. Is there some way anyone is aware of to configure both final and envelope senders based on email headers (that doesn't involve lda flags, these are on different systems), or am I currently out of luck? I've tried playing with DSN ORCPT but it seems like a non-starter trying to get it passed through (exim) -- David Zambonini

Yes, your understanding is basically correct. However, history gives lots of examples of broken systems that explicitly or implicitly relied on one critical system not failing -- they lacked defense in depth or resilience. Examples are "this system has no bugs", "my system does not leak hashes", "this algorithm is unbreakable", "we'll never see a CAT5 hurricane", etc. If these critical assumption ever becomes untrue, the foundation of your defense crumbles. If you narrow your attack definition to only include in-protocol remote brute forcing, then any decent password will take far too long to break that way (esp. with throttling controls that are built-in). Your log files will overflow recording the attempts long before you can expect a password to be cracked. However, you're still susceptable to the qwerty passwords. If this is your *only* line of defense, it is brittle. A robustly secure system will overlap protection: strong hashes, password compliance systems, brute force countermeasures, file permissions/OS hardening, network origins vetting, anti-DoS measures, etc. Keep this picture in mind that I found on CLCERT https://www.clcert.cl/humor/img/weakest-link-road.jpg Joseph Tam <jtam.home(a)gmail.com>

Dovecot and the Maildir path
by Will Merkens 30 Oct '17

30 Oct '17

System basics Centos 7.3 Dovecot 2.2.32 (dfbe293d4) I am working on a replacement mail server for work and one of the features I wanted was ldap authentication After much fiddling I got it to work. But I encountered a issue where two different methods of testing a mail account resulted in the mail_location being different I set mail_location = maildir:/var/spool/maildir/%d/%n/Maildir in dovecot.conf when I test the authentication and to see if the folders are created correctly on first use I have two results depending on how I test. First test was from openssl openssl s_client -connect mail2:993 I have no problem connecting, I issue the following commands * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. a login testuser(a)userful.com ******** a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE] Logged in a list "" * * LIST (\HasNoChildren) "." INBOX a OK List completed (0.001 + 0.000 secs). * BYE Disconnected for inactivity. closed But when I look in the mail server at /var/spool/maildir the testuser is not created inside of userful.com but at the same level as userful.com contrary to the %d in mail_location settings.
