    Hello, since v66 of whm, we now have Dovecot compression.

    I read up on it, and understand by activating it, it will compress future emails from either mdbox or maildir accounts.

    Does this option affect reliability in any way ? as in data corruption or unable to read the compressed emails (using webmail or a client like outlook per example)?

    Thank you

    Hello,

    I've not seen reports of any compatibility problems with email clients, or with data corruption, with the use of email compression. However, keep in mind cPanel 66 is only released to the Current build tier at this time. You may want to wait until cPanel 66 is in the "Release" or "Stable" tiers before using the feature if you are concerned about potential issues on a production system.

    Thank you.

    Hello @cPanelMichael

    Thanks a lot for the swift response. Indeed I forgot it was on Current build. But still thank you for answering.

    The default comression level is 6 but how high can you set it to? 10? 99?

    Here are the requirements for this value:
    • “Compression Level” must be an integer.
    • “Compression Level” cannot be less than 1.
    • “Compression Level” cannot be greater than 9.
    Thank you.

    Thanks for the info cPanelMichael.
    Wow this compression tool has saved GBs of space!! To compress already saved messages do the following:
    1) enable compression
    2) In WHM>>email>>>Mailbox conversion, change users mailbox format ( example maildir to mdbox ) and then change back again.
    Using the above method, on level 6 compression a users mail directory inbox of 5.5 GB mail box dropped to 3.5GB :)
