    Hello,

    Internal case CPANEL-7829 is open to address an issue where the vsz_limit configuration value for Dovecot is too low on 64-bit systems. I'll update this thread once a resolution associated with this case is published. In the meantime, the temporary workaround is to manually modify the following Dovecot configuration value to "512" via "WHM >> Service Configuration >> Mail Server Configuration":

    Maximum Size of a Mail Process (MB)

    Thank you.
