Migrate any mail server to hestiacp (vestacp fork)

My friend asked me to help with the migration of mail from a server running ispmanager5 lite to a server running vestacp. But this script is suitable for migration from any imap server to hestiacp panel.
I found imapsync utility and I'll use it. The email.txt file should contain a list of mailboxes and passwords, one account per line.

iptables geoip too many countries specified

iptables

Знадобилося заблокувати деякі країни однією строкою:

iptables -I INPUT -m geoip --src-cc
AR,BR,CN,CO,DZ,HK,IN,IR,KP,LA,MY,OM,PK,SC,TH,TW,VN -j DROP

Але отримав таку помилку:
iptables v1.6.0: geoip: too many countries specified

Оскільки я використовую кастомне ядро - я збираю xtables-addon самостійно.
Отже, нам потрібно збільшити XT_GEOIP_MAX та перезібрати.
