  dovecot: lmtp: Error: dovecot/lmtp: error while loading shared libraries: libdl.so.2: failed to map segment from shared object: Cannot allocate memory

  
  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.
