    Hello,

    I've been reading alot of threads concerning this conversion, but haven't been able to determine a few pre/post preparation for this conversion. So I have a few questions on this before we do the conversion.

    1) Do we need to contact all our hosting accounts prior to the conversion so they can retrieve emails from their current inbox?

    2) Will any emails be lost after the conversion?

    3) Do we need to make manual changes after the conversion?

    4) Will this affect how email is retreived via client's email reading, IE: Outlook ..etc., ?

    5) Will this affect Horder and/or Neomail mail in their Cpanels when checking mail?

    6) Does this have any direct effects on Exim and it's current configurations?

    7) How will this affect futher Cpanel updates, mainly STABLE.?

    8) Can the conversion be reversed if neccessary?

    I think that covers the questions I have before doing the conversion, but if any other pits falls or advantages, please let me know.

    TIA,
    Mickalo

    Not in this respect. Existing mail will be converted to the new format.

    Users will, however, not be able to either retrieve or send mail during the conversion process (as far as I remember) and so it may be worth advising them of this and informing them of when the conversion will commence.

    If the conversion works, all pre-existing mail will still be available.

    No.

    It shouldn't make any real difference. IMAP users may have to re-subscribe to their folders once conversion is complete.

    Neomail will be removed as it is not compatible with the maildir mailbox format. Horde and squirrelmail will still be available. Since the webmail apps use IMAP, users may have to re-subscribe to their folders to see all messages (same as above).

    Not in the slightest.

    This should make no difference to future cPanel updates. The maildir format has been the default format in all trees for some months now.

    You can choose to backup existing mailboxes prior to the conversion and you have the option of reversing the process once it's complete. Reversing the process will only restore mailboxes to the condition they were in prior to the conversion commencing - any mail retrieved in-between will probably be lost.

    Thanks so much, this helps alot.

    what is the real advantage to doing the conversion from the old system, this I haven't quiet figured out yet ??

    is there some sort of a scripts similar to the convert2maildir that can do the conversion back if needed or is this something that has to be done manually ??

    Thanks again for your help ... much apprecited. ;)

    Maildir improves performance and reliability. Everyone will need to eventually switch to maildir, as support for the old format will be dropped at some point in the future.

    After maildir conversion on some servers it seems that a sudden hike in mailbox sizes. almost double. That is unwanted copy of existing mails to default account folders or the delivery fail mails accumulating.

    If you would like to empty all the mails in default accounts after conversion.
    you can remove the contents of all default users cur folders by executing `rm -f /home/user/mail/cur/*`. <<--- use at your view/risk

    Also regarding converting back to the old format after maildir conversion
    # /scripts/convert2maildir
    Once you run the above script you will see the option to backup your mail accounts. You can restore them anytime and get back to the old format.

    If you perform the restore very late, you will probably mess up with new mails.
