Move old dovecot IMAP messages to another account

Thanks fosiul01 but I want to move anly the massages received more than 3 months ago :-)

if you want to move from last 3 month : you will have to write some bash script i guess, which i am nto that expert.

but i will have a look if i can get any work way round

in the mean time, other EE might be helpfull

Thanks Redimido!

The imapsplit utility is fine but how do I set the regexp expression ('match_regexp') to match the messages that have been received more than 3 months ago?

imap_servers = [
    # IMAPS server at somewhere.com
    {'type': 'imaps',
     'host': 'somewhere.com',
     'user': 'chochko',
     'password': 'mochko',
     'split_rules': [{'target': 'ros-dev',
                      'match': 'header',
                      'match_regexp': r"^List-Id:  *ReactOS Development List  *<ros-dev\.reactos\.com>$"
                      },
                     {'target': 'miscellaneous',
                      'match': 'always'
                      }
                     ]
     },


Many thanks in advance :-)

Could finally someone give me an appropriate suggestion? WHERE ARE THE EXPERTS?

hmmm nobody knows.... ????? strange.....

I'm sorry because I am not an expert, but I will still try to help:

just looking at the packages suggested, I see this page
http://imap-agent.sourceforge.net/IMAP-Agent.htm

Looks like imap-agent is a good tool for mails that are X days old (I read imapsplit and cannot think of a good regular expression that matchs old emails since there is no actual date variable to use. sorry it took to much for me but I understand my advise is what you were looking for and not me doing the actual job for you)

well, to the point:
check "ADDITIONAL].XML Sample File" and the information for age="XXX" where you can state the age of emails you want that rule to match.

here we can match emails older than 90 days, so it works for what you need.

  <user name="cat" logon="cat"  >
    <rules Note="folder tags are processed in the same order you see here">
      <folder name="INBOX">
        <rule testtype="custom" to="Keep" searchscope="message">G:\\cvs\\plugins\\CustomRule\\custom_rule_plugin\\bin\\release\\plugin_custom_rule.exe</rule>
      </folder>
      <folder name="Keep">
        <rule  to="Keep2" searchscope="from" smwa="0"><![CDATA[^lister@domain1.net$]]></rule>
      </folder>
    </rules>
    <aging>
      <folder name="Keep" age="3" maxcount="15"/>
      <folder run="n" name="Keep2" age="5" maxcount="5"/>
    </aging>
  </user>
 
just check the manual and try

Many many thanks Redimido !
I will try if it works... :-)))

ehhh.... nothing to do.... because, as I read (maybe I misunderstood it), the Age attribute in the imap agent is used for definitively deleting emails older than (Age) days and not for moving them to a different folder and (what is my goal) for moving them to another  namespace (dovecot user).... anyways many thanks Redimido for the help

Age:
Meaning number of days old.
All email older than (Age) days is deleted.  The MIME Date: header is where the email date is taken from.!
Note: Deleted messages are not moved to the mailbox Trash folder, but are immediately expunged from the mailbox.  There is no ability to retrieve deleted messages.  

please recheck the web page. this Age attribute you read was for the <Aging> tag. the Age attribute I mean is for the <folder> tag.

To avoid any issue, delete the <Aging> tag and all its content. just use the Folder tag.

aha... :-) ok my error :-)) many thanks... I will check :-)
