[Dovecot] dsync replication errors
by Oli Schacher 09 Sep '15

09 Sep '15

Hi I'm trying to build a cluster of two servers with dsync replication (based on http://wiki2.dovecot.org/Replication). My test setup works fine for very simple tests, I can log in to both servers, copy a message to one of the servers and it successfully apperars in the other account. But, if I try to copy a large amount of messages at once to one of the accounts, my maillogs get flodded with errors(see below) and the mailboxes seem to get out of sync and messages are duplicated over and over again (I originally copied 100 messages and ended up with thousands in both mailboxes until I killed dovecot) I'd appreciate if someone could have a look at my config and tell me what I did wrong. dovecot.conf of both servers, they are identical except for the target ip in mail_replica: dovecot -n # 2.2.beta1 (070ca24e5846+): /etc/dovecot/dovecot.conf # OS: Linux

Different behavior of ACLs in MUA and doveadm
by Thomas Leuxner 08 Sep '15

08 Sep '15

I have noticed a difference in the behavior of ACLs. When used in a MUA the following global ACL works fine and has the desired effect - new mailboxes can be created by a user being part of the 'PublicMailboxAdmins' group: [ global-acl: ] INBOX owner lrwstiekxap Public/* group=PublicMailboxAdmins lrwsipk Public/* anyone lr Public/* authenticated lrws Creating the same mailbox via doveadm however fails with a permission problem: doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/dovecot-acl not found doveadm(tlx(a)leuxner.net): Error: Can't create mailbox Public/Archive/Newsletters/heise-security/2014: Permission denied Interestingly, doveadm succeeds when dovecot-acl is present in the namespace root - which of course is not desirable in the light of the global ACL: [ dovecot-acl: ] group=PublicMailboxAdmins lrwsipk doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: reading file /var/vmail/public/mailboxes/dovecot-acl doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014 doesn't exist yet, using default permissions doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: Using permissions from /var/vmail/public: mode=0700 gid=default doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found # 2.2.15 (6078354e6238): /etc/dovecot/dovecot.conf I know there have been some changes in Mercurial as to how global ACLs are interpreted. Is doveadm probably behind on them? Regards Thomas

Hello folks, Any plans on implementing the PROXY protocol to allow Dovecot being behind a TCP proxy, and still logging the real IP address of the users ? See : http://blog.haproxy.com/haproxy/proxy-protocol/ Thanks !

Hi, I have noticed that during auth cache hits usernames are not updated. (We use ldap backend and change username with user_attrs = uid=user, mailMessageStore=home, mailQuotaSize=quota_rule=*:bytes=%$ cold cache lmtp(14414): Debug: auth input: testmon_testmon home=/vmail/te/testmon_testmon quota_rule=*:bytes=104857600 lmtp(14414): Debug: changed username to testmon_testmon lmtp(14414): Debug: Added userdb setting: plugin/quota_rule=*:bytes=104857600 hot cache lmtp(14715): Debug: auth input: iqmon(a)mon.test.pl home=/vmail/iq/testmon_testmon quota_rule=*:bytes=104857600 lmtp(14715): Debug: Added userdb setting: plugin/quota_rule=*:bytes=104857600 this kills our dictionary based quota (users have multiple quota instances depending on timing and alias the email was delivered to. Is there a way to force addition of user to the auth cache ? -- Michal Grzedzicki

[PATCH] increase fd_limit to max_client_limit automatically
by Lauri Tirkkonen 23 Mar '15

23 Mar '15

Hi, with a low soft limit on file descriptors, dovecot 2.2.15 warns on startup: Warning: fd limit (ulimit -n) is lower than required under max. load (256 < 1000), because of default_client_limit It could try increasing the limit first, and only report the warning if that fails. I'm attaching a patch that does just this. Without the patch, the soft fd limit is kept at whatever it was on dovecot startup: % pfexec plimit $(pgrep dovecot) 18737: /opt/niksula/sbin/dovecot resource current maximum time(seconds) unlimited unlimited file(blocks) unlimited unlimited data(kbytes) unlimited unlimited stack(kbytes) 10240 unlimited coredump(blocks) unlimited unlimited nofiles(descriptors) 256 65536 vmemory(kbytes) unlimited unlimited and with patch applied, it's increased to max_client_limit: % pfexec plimit $(pgrep dovecot) 18775: /opt/niksula/sbin/dovecot resource current maximum time(seconds) unlimited unlimited file(blocks) unlimited unlimited data(kbytes) unlimited unlimited stack(kbytes) 10240 unlimited coredump(blocks) unlimited unlimited nofiles(descriptors) 1000 65536 vmemory(kbytes) unlimited unlimited It should probably be increased to higher than that to account for fds other than client sockets, but I don't have insights into that. -- Lauri Tirkkonen Niksula systems specialist

[Dovecot] imapc - different settings for different namespaces
by Timo Sirainen 20 Mar '15

20 Mar '15

Originally I was planning on allowing all kinds of mail settings inside namespace {}, including imapc_* settings. But that's a bit difficult to implement (although I think it will happen some day). So for now I was thinking: imapc foo { host = imap.foo.com master_user = foomaster password = foopass } imapc bar { host = imap.bar.com ... } namespace { prefix = foo/ location = imapc:foo } namespace { prefix = bar/ location = imapc:bar } So basically if the path after imapc isn't absolute (/path or ~/path), then treat the path as the imapc section name and use its settings. Anyone have any improvement suggestions? I was planning on adding this to v2.2.3. I'm not sure if the section names should be "imapc" or something else (e.g. imap_remote {}).

[Dovecot] Sieve vacation not working
by Phill Edwards 24 Feb '15

24 Feb '15

I've been trying all night to get vacation working in my .dovecot.sieve file. The way our email works is we have one account on dovecot which serves my mail and my wife's and we use procmail and sieve to put the emails in different folders depending on who it's for. I'm trying to set up a vacation reply on my wife's email address (aaaaaaaa@optus* below) so people can update to her new address. Here's my file with the email addresses masked: require ["fileinto", "vacation"]; if address :is "to" "xxxxxxxxxxxxxxx(a)ozemail.com.au" { fileinto "Phill_OzEmail_Folder"; stop; } elsif address :is "to" "yyyyyyyyyyyyyyyyy(a)optusnet.com.au" { fileinto "Phill_Optus_Folder"; stop; } elsif address :matches "to" "aaaaaaaa@optus*" { vacation "Please update my email address to bbbbbbbbb(a)exemail.com.au"; fileinto "Sarah_Optus_Folder"; stop; } else { keep; stop; } The problem I'm having is that no auto-replies are sent. I removed .dovecot.lda-dupes and that didn't help; so then I touched it and now it's a 0 byte file and that didn't help. There is no dovecot.sieve.err file and I can't see anything in /var/log/dovecot.log which gives any message about why this wouldn't work. The emails to aaaaaaa@optus* get filed into the right folder so I know the matching is working. I've also tried a reject recipe and that worked fine, so I know that it can send an email if it chooses to. So it's a complete black box mystery as to why it just won't send a reply. Regards, Phill

Permissions for shared mail don't work
by Damien Desfontaines 17 Feb '15

17 Feb '15

Hello, (Sorry if you already received this mail. I sent it without having subscribed to the list, but I never got any confirmation; so I assumed it has been filtered by the anti-spam or something.) I'm using dovecot v.2.1.7 on Debian Sid, and the output of dovecot -n is available here: http://paste.fulltxt.net/C-O I'm trying to make the mailbox of (system) user "spam" available to user "ted". I followed these instructions: http://wiki2.dovecot.org/SharedMailboxes/Permissions and it doesn't seem to work. To be more precise: - I manually (and recursively) changed the permissions of all files in ~spam/Mail to 660 (and 770 for the directories); - I manually (and recursively) changed the group owner of everything in ~spam/Mail to "mailperso", where "mailperso" is a group whose users are spam and ted; - I added « mail_access_groups=mailperso » into my dovecot config; - and I restarted dovecot. But still, when I send a new email to spam, it appears as being owned by group "spam" and having permissions set to 600, so I can't access it with user "ted". I also tried to set the setgid bit for ~spam/Mail, it didn't change anything, and when I recursively set the setgid for all subdirectories of ~spam/Mail, it gives new mails the correct group (mailperso) but not the correct permissions. Have I missed something, or is this a bug? Thanks in advance and best regards, Damien
