mail migration usermail size

[kmuralidharan]

hi ,

we are testing zimbra server successfuly. we have to plan launch the zimbra server
within the week. i ask some question's .
1. for that bulk migration script , i need --authmech1 LOGIN --authmech2 LOGIN . In that
bulk migration script default plain authetication is available( i thing)
any other script for my requirement. the following single user migration works fine

./imapsync --nosyncacls --subscribe --syncinternaldates --host1 192.168.1.12 --user1 kmuralidharan --passfile1 /etc/secret1 --host2 192.168.1.96 --user2 kmuralidharan --passfile2 /etc/secret2 --authmech1 LOGIN --authmech2 LOGIN

2. while mail migration any limitation for usermail size (existing mail server ).
or unlimit size per user inbox ?
