Re: [Dovecot] piegonhole sieve prepending header lines with an extra space
Hi Stephen, I finally had a chance to re-test this and confirm that v4.1 of the plugin does fix the problem. Thanks for your assistance.

I'm not clear because you already have a release (v4.1) which does contain that patch; are you suggesting that an upgrade to that version might help? Oh, right, it is already released. So, yes, upgrade. Regards, Stephan.

Since your next-hop MTA is also Exim, this may have the same root cause. Please try to apply this change and see whether this problem persists. If this fixes it, I should make a new release soon. When the problem persists, try to capture the outgoing message before it enters the MTA, e.g. by pointing sendmail_path to a shell script that saves the message somewhere. That way we can see what mail is actually being sent to the MTA. Regards, Stephan.

Hi Stephan, Attached is the configuration and both the original message as received (sieve redirect test.eml) and what it was like at the location where the redirect was received (1373811315.24616_23.niflheim:2,S) Let me know if you need anything else to diagnose the problem.

Bizarre. I haven't seen this before, I cannot reproduce it and I don't see how Sieve could be introducing additional spaces. Anything is possible, but are you sure this is caused by Sieve? Is `sieve redirect test.eml' the same as what is saved by Sieve using fileinto? I'm wondering what exact message is being passed to Sieve, since this problem could also be caused by the LMTP transfer. Regards, Stephan.

The only sieve script in use is:
if anyof( address :is to akum...@acm.org, exists List-ID)
{
redirect wildf...@progsoc.org;
keep;
}
Is `sieve redirect test.eml' the same as what is saved by Sieve using
fileinto? I'm wondering what exact message is being passed to Sieve, since
this problem could also be caused by the LMTP transfer.
I'm not sure what you mean by your first question, but from what I
understand if there was no 'keep' in the above script I would not have a
local copy.
As I said, my suspicions are on 'mail_crlf_save = yes', since that *is*
specifically modifying the headers associated with the message.
Regards,
Anand

[Dovecot] piegonhole sieve prepending header lines with an extra space
Hi, I've noticed that the redirect sieve extension is placing an extra space before the headers of email when the 'redirect' command is used. Unfortunately this break gmail, yahoo, and most other email programs. I am using pigeonhole 0.4.0-14 with Dovecot 2.2.4.3; I see change 1781:e439789e3211 but it appears to only change how the X-Sieve header is generated. I only have the one dovecot instance but I will note that the setting 'mail_save_crlf = yes' is specified. Thanks, Anand
