Re: [Dovecot] mdbox-files not approximately 2 MB

[Hardy Flor]

Depending on a defined mail extent a new file should be created. 
However, I am not clear what is used as this Mail extent.
Does the application use the entire contents of a mail (including 
attachments), or only the mail contents without the actual attachment?

BUG: segfault in auth when user listed multiple times in LDAP

[Laszlo Toth]

Hi,

I think I found a bug in the auth module. It can be triggered when the 
userdb is in LDAP and an user is found multiple times in LDAP.


Dovecot version 2.2.10 (from ATrpms Testing) running on CentOS 6.5 x64.

Jun 27 10:34:34 server dovecot: auth: Debug: ldap(USER): user search: 
base=dc=linguamatics,dc=com scope=subtree filter=(  (uid=user) (|

If more information is needed just let me know. I have the core dump but 
I was not able to find the debuginfo package for the installed Dovecot 
packages to extract the trace.


Thanks,
Laszlo

mail_attachment_dir backup was  not from the same time.

Procmail to Sieve translation

[Gerhard Wiesinger]

Hello,

I'm trying to move from procmail to dovecot sieve.

I found the translation script at 
http://www.dovecot.org/tools/procmail2sieve.pl

It works well except the following use cases:

* ^From:.*myem...@mydomain.com.*
| formail -IX-Priority: 2 (high) -IX-mydomain-com-seen: yes | 
$SENDMAIL -oi \

  myem...@mydomain2.com  \
  myem...@mydomain3.com

:0c
* ^From:.*myem...@mydomain.com.*
! +1123456...@mysmsprovider.com

:0c
* ^(To|Cc|Bcc):.*myem...@mydomain.com.*
!   myem...@mydomain2.com myem...@mydomain3.com

Is there a possibility to support these use cases (can be done manually)?

How does forwarding to another domain work at the deliver process?

:copy seems not to be supported, right?

Thank you.

Ciao,
Gerhard
