Turned out that default option “Pages per sheet” in CUPS was reset to 4.

In order to set default value of “Pages per sheet” in CUPS to 1:
1)Stop cups: /etc/init.d/cups stop
2)edit file /etc/cups/printers.conf and set
Option number-up 1
3)Start cups: /etc/init.d/cups start

upload_max_filesize = 32M
post_max_size = 32M

2)Set local limits in /usr/share/roundcube/.htaccess

php_value upload_max_filesize 16M
php_value post_max_size 17M
php_value memory_limit 256M

P.S. Perhaps you will need to adjust your Postfix SMTP server message size limit in /etc/postfix/main.cf

message_size_limit = 33554432
