lda: Warning: Failed to parse return-path header: Invalid character in localpart
by Christian Authmann 01 Feb '18

01 Feb '18

Hello, Sometimes, when delivering mails, this warning appears in my syslog: > lda(...): Warning: Failed to parse return-path header: Invalid character in localpart dovecot-lda still exits with 0 and the mail is inserted into my inbox. Looking at the mails in question, I determined that the error is caused by a multiline Return-Path header. Here's a testcase: --- snip --- Return-Path: <nowhere(a)example.com> From: "Nowhere" <nowhere(a)example.com> To: redacted(a)example.com Subject: Testcase for lda warnings Date: Wed, 31 Jan 2018 12:00:00 +0000 This is a message body. --- snap --- Copy into a file, with \r\n line endings, then run something like this: > cat testcase.txt | /usr/lib/dovecot/dovecot-lda -e -d '<username>' with a username recognized by your running dovecot installation. The header is 'Return-Path:', \r\n, two spaces, '<...>', \r\n According to rfc2822 folding rules, that should be valid - the Return-Path header allows CFWS at that location. The error message originates in lib-lda/mail-deliver.c in mail_deliver_get_return_address(), while the invalid character message seems to originate from one of several places in lib-lda/mail-deliver.c Ciao, Christian Authmann

send specific NDR message for users in certain OU
by lists 30 Jan '18

30 Jan '18

Hi, The question can perhaps be made more generic like this: Can dovecot generate a *specific* NDR (or an autoreply) for accounts that meet a specific criterium, such as: - user account was found under OU=to-delete,CN=company... contrary to the regular location CN=Users,CN=company... We would like to move to-be-deleted users to this container, before actually deleting them. That gives us an easy way to revert, if the deletion turns out to be erroneous. We could do that with via a sieve config for those accounts, but if dovecot could send a "delivery failure"-type specific for those accounts (with instructions who to contact to revert the situation) it would be very easy: only move the user to the specific OU, and have the system do the rest. Can this be done? (dovecot 2.1.17 on wheezy, yes we know we should upgrade, and we also will, but it runs rock solid...) MJ

2 panics, 1 segmentation fault in dovecot 2.3.0 (fts)
by Infoomatic 30 Jan '18

30 Jan '18

Hi, While testing our migration to dovecot 2.3.0, we encountered 2 panics, 1 segmentation fault while we wanted to rebuild the solr indizes. Problem [1] was encountered while rebuilding the indizes, and now I don't know how many mails/documents are indexed or where it got stuck. [2] and [3] encountered while just playing around, since I did not know of "tokenize" and did not find a lot of information about it. This is a ubuntu 16.04 machine, dovecot 2.3.0 compiled from source ( + the patch for the recent zlib problem). "doveadm index" runs on a ~ 4GB mdbox-zipped-mailbox for about 3-4 minutes before aborting with the message above, beforehand I did a "/opt/dovecot/bin/doveadm fts rescan -A". When I repeat "doveadm index" it aborts after about 4 seconds, after a "/opt/dovecot/bin/doveadm fts rescan -A" it runs again for 3-4 minutes. Apache tika logs, but those are probably not related to the problem, however, the devs might want investigate the last line: WARN Parse exception Expected ';', got "," determining content disposition javax.mail.internet.ParseException: Expected ';', got "," and org.apache.tika.exception.ZeroByteFileException: InputStream must have > 0 bytes I would be happy if you could have a look at this, please, and of course just tell me what further information you need.

Hi, I have the following command for retrieving mails from another IMAP mail server dsync -D -v backup -R -u jon.doe imapc: I't ok and works, but I'd want to copy messages outside of /var directory, is there a way to do that?
