Mail forwarding loop while restoring old mails

[Sachin Acharya]

Hi,

I imported some old mails using pilerimport command and accessed the mails on mail piler. But when I try to restore an old mail, I get the following error in /var/log/mail/log :

Jun 13 16:16:38 mail postfix/pipe[3828]: 90E194271: to=[e-mail], relay=dovecot, delay=1.1, delays=1.1/0.01/0/0.04, dsn=5.4.6, status=bounced (mail forwarding loop for [e-mail])

piler -V is as follows:

piler 0.1.24-master-branch, build 836, Janos SUTO [e-mail]

Build Date: Fri May 30 16:16:00 IST 2014 ldd version: ldd (Debian EGLIBC 2.13-38+deb7u1) 2.13 gcc version: gcc version 4.7.2 (Debian 4.7.2-5) Configure command: ./configure --localstatedir=/var --with-database=mysql --enable-starttls --enable-tcpwrappers

What is your setup like? Do you have postfix and piler on the same host?

[Sachin Acharya]

Yes I have piler and postfix on the same host. I am able to restore new mails without any problem. Only the mails that were imported are the ones that are giving that error message.

[Sachin Acharya]

In all the mails that are giving status=bounced, I noticed that the message header contains "Delivered-to: [e-mail]" line. I don't know if that might be of any help. But just making you aware of it.

[Janos SUTO]

Try the following: edit config-site.php, and set SMARTHOST to point to your mail server where your mailboxes are.

[Sachin Acharya]

It was already set to point to the mail server which is the localhost itself.

Many online resources told me that it is due to the Delivered-to: [e-mail] line in the message header that this forwarding loop occurs. Could you please help on how to resolve this issue?

[Sachin Acharya]

Just FYI, I tried to restore a mail to an address that was not mentioned in the Delivered-To: line. That mail was restored with a status= sent. Its happening only to those id's that are mentioned in the Delivered-To line.

[Janos SUTO]

Try to set the following in config-site.php:

$config['RESTORE_EMAILS_AS_ATTACHMENT'] = 1;

This causes the gui to send the restored email as an attachment.

[Sachin Acharya]

It didn't help. I'm getting the same error message when I try to restore the mail.

[Janos SUTO]

Ehh, I was wrong: 0.1.24 doesn't have this feature. You need the master branch to try it.

Btw. how is it possible that some emails have and some don't have the "Delivered-to: " header?

[Sachin Acharya]

Isn't mine already master branch'd? If not can you give me the link to do so?

Well, I've been told that prior to 2010, they were using a different server and post 2010 they used a new server and only post-2010 are all the mails having the "Delivered-to:" header.

[Sachin Acharya]

Its working now. I did the following:

create /etc/postfix/header and add the following into the file: /^Delivered-To:.*/ REPLACE X-Bad-Delivered-To: removed

edit main.cf and add the following line: header_checks = regexp:/etc/postfix/header

then restart postfix.

This is working.
