Using "imtest -m PLAIN -u u...@example.ca -a ad...@example.ca

Executing ". list *.*" produces the expected list of u...@example.ca's

Using "imtest -u u...@example.ca -a ad...@example.ca" (Note: no

PLAIN, and I'm successfully able to log in.

However, the ". list *.*" command now produces a list of every folder
in the example.ca subdomain, not just the specified user's mailbox.

Anyone know what's going on here?


The LOGIN mech does not support proxy authentication:

Ok. Thanks you.

Still one question, I see in the configuration file

  conversations_expire_days : 90

why do I need to keep those information during 90 days ?  For example what
would be the impact if I say

  conversations_expire_days : 7

Thanks for you help

Regards.

Virtual domain admin login behaviour

I have a mail server still running an older version of Cyrus IMAPD
(version 2.3.16) on CentOS 6 with virtual domains, using OpenLDAP as
an authentication backend with saslauthd for LOGIN/PLAIN when SSL/TLS
is used.

I recently set up a domain admin account for one of the virtual
domains in order to facilitate transfer of mail from that domain to a
different mail host, and while I was testing the setup I noticed some
inconsistent behaviour.

Using "imtest -m PLAIN -u u...@example.ca -a ad...@example.ca
mail.example.ca", I'm successfully able to login.

INBOX and subfolders.

conversations.db initially was used to keep an index of email conversations 
(e.g. the threaded views typically found in most email readers nowadays). But 
today it also helps for most use-cases where we need to keep track of messages 
across mailboxes (e.g. if you have two copies of an email in two mailboxes, 
you'll see that reflected in conversations.db). It confusingly is still named 
conversations.db for historic reasons. But for any recent (v3) Cyrus IMAP 
installation, including Xapian and JMAP, it's a very critical piece in the 
puzzle.

Cheers,
Robert
