Postpone email delivery with LMTP and Postfix
by Miloslav Hůla 01 May '15

01 May '15

Hi, is there any way, based on userdb/passwdb attribute, how to postpone an email delivery? The purpose is, I need to freeze an account (Maildir++) for a few minutes and new email must not be delivered. But emails must be delivered when account is unfrozen. I found few things about Postfix filters, but I'm not sure it's a good way. Thank you, Milo

A question about Configure time options, and base directories and Defaults?
by Robert Chalmers 30 Apr '15

30 Apr '15

I originally downloaded the sources a few weeks ago, dovecot-2.2.16, and simply did a ./configure make make install I'm running OSX 10.10.3 on a mac-mini. Not being too sure that I was going to go ahead with this whole idea... in any event, I did. BUT... most documentation I come across as I search for answers refers to the base directories being below /etc - as in postfix actually. ie; /etc/dovecot /etc/postfix Which seems logical to me - and appears to be a "default" or standard, at least in most documentation. However, my cavaliere installation put everything below /usr/local, as in /usr/local/etc/dovecot Which has caused me no end of fiddling as I try and remember where things are when I'm working on config files. There even appears to be a /private/etc/dovecot folder, which I seem to have somehow created about a month ago??? but is empty anyway. So, on my Mac I now have these folders/directories. These may have been created by a previous attempt, or by an installation to CutedgeSystems Mailserve. Now redundant. /private/etc/dovecot <---- empty /private/etc/pam.d/dovecot <--- contains login, pop3, ssh etc etc /private/var/spool/postfix/private/dovecot <-- this is a link to the one just above ??? or the other one is a link to this? /usr/libexec/dovecot <-- this contains a link to dovecot-lda [dovecot-lda -> /usr/local/libexec/dovecot/dovecot-lda] that I put in myself because that's where dovecot was looking for it. ========= everything below this line is as a result of the installation from source /usr/local/cutedge/dovecot /usr/local/etc/dovecot /usr/local/include/dovecot /usr/local/lib/dovecot /usr/local/libexec/dovecot /usr/local/sbin/dovecot /usr/local/share/doc/dovecot /usr/local/var/lib/dovecot /usr/local/var/run/dovecot I see from this list in someone else's post, that it's obviously possible - and I should have remembered - to put the files where ever I want them. i.e. /etc/dovecot If I read this list right, it will put the installation into /etc/dovecot - with some in other, appropriate directories. NOT all below /user/local as I have done. --prefix=/usr \ --sysconfdir=/etc \ --libexecdir=\${prefix}/lib \ --localstatedir=/var \ --mandir=\${prefix}/share/man \ --infodir=\${prefix}/share/info \ --with-moduledir=\${prefix}/lib/dovecot/modules \ --disable-rpath \ --disable-static Now for the burning question. Is it possible now to re-configure, then reinstall into the more appropriate directories, then copy the configuration files over. Make the appropriate weeks, and remove the original /usr/local/xxxx installation? Or is that just a step too far for the sake of what is essentially window dressing. The system I might add appears to be working as is? Thanks for any advice from the experts. (Sorry if the formatting in this post gets screwed up. It;s gmail;s web interface) Robert

doveadm -D and -v options

30 Apr '15

According to doveadm-dsync man page the above two options are valid, but they are rejected when used: tornado # doveadm backup -v -u testuser remote:pi.me.name:4814 backup: invalid option -- 'v' doveadm backup [-u <user>|-A] [-S <socket_path>] [-fPRU] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-g <mailbox_guid>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] -d|<dest> tornado # tornado # doveadm backup -D -u testuser remote:pi.me.name:4814 backup: invalid option -- 'D' doveadm backup [-u <user>|-A] [-S <socket_path>] [-fPRU] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-g <mailbox_guid>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] -d|<dest> tornado # This is with 2.2.16 (latest -hg). Looks to me like either a bug, or the documentation (man doveadm-sync) is incorrect...? Reuben

quota_over_flag examples?
by E.B. 30 Apr '15

30 Apr '15

I can't find any posts on this list for peoples using quota_over_flag http://wiki2.dovecot.org/Quota/Configuration#Overquota-flag_.28v2.2.16.2B-.… If my userdb is sql what would be best script to use in terms of performance? (I mean if over-quota-flag triggers script every time it changes and the script calls CLI mysql client isn't all this so expensive to spawn a new shell session which spawns a mysql client?) Anyone knows how to use this flag with postfix *making postfix send special reject* "user over quota" note instead of plain SMTP reject?? Is an additional database lookup (restriction class?) unavoidable? :( TIA1 PS Looks like it is tricky almost impossible to make postfix do rejects based on this flag for aliases. (Special query would be a little messy for our schema but i dunno at what point postfix resolves aliases?)

lda and lmtp error after upgrading dovecot
by giorgio paolucci 29 Apr '15

29 Apr '15

Hello everybody, after upgrading dovecot on a debian wheezy installation from the standard package version (dovecot 2.1.7) to dovecot 2.2.13-11 from wheezy-backports, i noticed some errors in my logs... Apr 28 22:00:13 lmtp(4879, xxxxxxxxx(a)unipd.it) Info: copy from <lmtp DATA>: box=INBOX, uid=error, msgid=<20150428200011.47D801F32(a)mydoom.unipd.it>, size=1523 They are not frequent but still coninuing since the upgrade. After the upgrade I found also errors coming fom lda: Apr 28 12:29:36 lda(userxxxxxx(a)unipd.it): Info: copy from stdin: box=INBOX, uid=error, msgid=, size=595 Apr 28 12:29:37 lda(userxxxxxx(a)unipd.it): Info: msgid=unspecified: saved mail to INBOX Strange thing as I use lmtp for local delivery. Is there some tuning I can do? My storage is accessed via NFS with a load blancer keeping sticky sessions "per user". Is there any risk to loose mails? Here is my dovecot -n Thanks in advance.

Trash Plugin bugs
by Alexei Gradinari 29 Apr '15

29 Apr '15

dovecot v2.2.16 I've found a few bugs in Trash plugin. 1. If Quota set only messages limit (without storage limit) then Trash plugin does not expunge any message because Quota plugin sets too_large_r=TRUE. It's because quota_default_test_alloc function does not check if bytes_limit is set. /* if size is bigger than any limit, then it is bigger than the lowest limit */ - if (size > bytes_limit) { + if (bytes_limit > 0 && size > bytes_limit) { *too_large_r = TRUE; break; } 2. Trash plugin does not use bytes_ceil/count_ceil to calculate size_needed/count_needed to expunge. Trash plugin may expunge more messages that nedeed. + if (ctx->bytes_ceil!=(uint64_t)-1 && ctx->bytes_ceil < size + ctx->bytes_over) { + size_needed = size + ctx->bytes_over - ctx->bytes_ceil; + } + if (ctx->count_ceil!=(uint64_t)-1 && ctx->count_ceil < 1 + ctx->count_over) { + count_needed = 1 + ctx->count_over - ctx->count_ceil; + } + /* not enough space. try deleting some from mailbox. */ - ret = trash_try_clean_mails(ctx, size + ctx->bytes_over, - 1 + ctx->count_over); + ret = trash_try_clean_mails(ctx, size_needed, count_needed); 3. Trash plugin does not check 'unlimited' values in bytes_ceil/count_ceil and may overflow them when add expunged size/messages - ctx->bytes_ceil += size_expunged; - ctx->count_ceil += expunged_count; + if (ctx->bytes_ceil!=(uint64_t)-1) { + ctx->bytes_ceil += size_expunged; + } + if (ctx->count_ceil!=(uint64_t)-1) { + ctx->count_ceil += expunged_count; + } See attached patch.
