외부 메일 client 접속 시 메모리 문제 발생

Hello Jake, The server is Dell 2950 CPU: Intel(R) Xeon(R) CPU L5320 <at> 1.86GHz x2RAM: 8GB DISK: 300GBx4 RAID5 = 898.3 GB Hello Erik,

I had removed the old packages. and installed the new packages.
These really are 64bit values by default.
imap4/run:/usr/bin/softlimit -m 48000000 \ 
imap4-ssl/run:/usr/bin/softlimit -m 48000000 \ 
pop3/run:exec /usr/bin/softlimit -m 48000000 \ 
pop3-ssl/run:/usr/bin/softlimit -m 48000000 \ 
smtp/run:exec /usr/bin/softlimit -m 64000000 \ 
submission/run:exec /usr/bin/softlimit -m 48000000 \

But I need change them higher like below.

imap4/run:/usr/bin/softlimit -m 48000000 \ 
imap4-ssl/run:/usr/bin/softlimit -m 48000000 \ 
pop3/run:exec /usr/bin/softlimit -m 64000000 \  #If not, erro from mail client, always input password, and can't login.
pop3-ssl/run:/usr/bin/softlimit -m 48000000 \ 
smtp/run:exec /usr/bin/softlimit -m 64000000 \ 
submission/run:exec /usr/bin/softlimit -m 64000000 \ #If not, error from log, connect refuse. libselinux.so.1 Cannot allocate memory
smtp-ssl/run:exec /usr/bin/softlimit -m 64000000 \ #If not, error from log, connect refuse. libmysqlclient.so.16  Cannot allocate memory

Thank you for dovecot, I will try it today.
