Increase dovecot vsz_limit

    Hello, imscp community.

    I have a problem with an email account with huge storage. The error I receive is,

    Code
    1. Aug 22 15:08:49 server dovecot: imap(xxx@xxxx.tld): Fatal: master: service(imap): child 17293 returned error 83 (Out of memory (service imap { vsz_limit=256 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump)

    The solution that I found on the web is to edit dovecot.conf so that the result would be the increase of that limit. In our case, imscp is going to overwrite the configuration file so solution in our case would be different.

    Any idea on how can I do this?


    Thanks!


    PS: I use Ubuntu 18.04LTS and imscp 1.5.3. All plugins and packages are up to the latest version possible.
