Usage

Single Account Migration

# Basic migration
./mail-migrator --src "user@domain.com:password@imap.source.com:993" \
                --dst "user@domain.com:password@imap.dest.com:993" \
                --insecure

# With logging
./mail-migrator --src "user@domain.com:password@imap.source.com:993" \
                --dst "user@domain.com:password@imap.dest.com:993" \
                --insecure --log migration.log

# With resume support
./mail-migrator --src "user@domain.com:password@imap.source.com:993" \
                --dst "user@domain.com:password@imap.dest.com:993" \
                --insecure --resume --log migration.log

Batch Migration

1. Buat file CSV (contoh: accounts.csv):

user1@domain.com:password1@imap.source.com:993,user1@domain.com:password1@imap.dest.com:993
user2@domain.com:password2@imap.source.com:993,user2@domain.com:password2@imap.dest.com:993
info@trieltree.co.id:P@ssw0rd123@10.10.11.30:993,info@trieltree.co.id:P@ssw0rd123@10.10.11.24:993

2. Jalankan batch migration:

./mail-migrator --batch accounts.csv --insecure --resume --log migration.log

URL Format

Format URL untuk source dan destination:

username:password@hostname:port

Contoh:

• user@domain.com:mypassword@mail.server.com:993
• info@trieltree.co.id:P@ssw0rd123@10.10.11.30:993

Password dengan Karakter Khusus

Jika password mengandung karakter khusus (@, :, /, dll), gunakan URL encoding:

• @ → %40
• : → %3A
• / → %2F
• % → %25

Contoh:

# Password: P@ssw0rd:123/test
# URL encoded: P%40ssw0rd%3A123%2Ftest
./mail-migrator --src "user:P%40ssw0rd%3A123%2Ftest@server:993" \
                --dst "user:P%40ssw0rd%3A123%2Ftest@server:993" \
                --insecure

Command Line Options

Flag	Description	Default
--src	Source IMAP URL	Required
--dst	Destination IMAP URL	Required
--batch	CSV file untuk batch migration	-
--insecure	Skip SSL certificate verification	false
--resume	Resume interrupted migration	false
--log	Log file path	-

Troubleshooting

1. Authentication Failed

Error: LOGIN Authentication failed

Solusi:

1. Pastikan credential benar:

   # Test dengan IMAP test tool
   cd tools
   go build -o imap-test.exe imap-test.go
   ./imap-test.exe <host> <port> <username> <password>
   

2. Coba format username berbeda:

   • username (tanpa domain)
   • username@domain.com (dengan domain)
   • username@mail.domain.com (dengan subdomain)

3. Periksa server capabilities:

   • Tool akan otomatis mencoba LOGIN dan AUTHENTICATE PLAIN
   • Check log untuk melihat supported authentication methods

2. SSL Certificate Error

Error: certificate verify failed

Solusi:

# Gunakan flag --insecure untuk self-signed certificates
./mail-migrator --src "..." --dst "..." --insecure

3. Connection Timeout

Error: connection timeout

Solusi:

1. Test koneksi manual:

   telnet <hostname> <port>
   # atau
   openssl s_client -connect <hostname>:<port>
   

2. Periksa firewall dan network

3. Pastikan port benar (biasanya 993 untuk IMAPS, 143 untuk IMAP)

4. Resume Migration

Jika migration terputus, gunakan --resume untuk melanjutkan:

./mail-migrator --src "..." --dst "..." --resume --log migration.log

State disimpan di file state.db menggunakan BoltDB.

5. Debug Mode

Untuk troubleshooting detail, check log file atau console output:

./mail-migrator --src "..." --dst "..." --log debug.log

Log akan menampilkan:

• Server capabilities
• Authentication attempts
• Message copy progress
• Error details

Tools

IMAP Test Tool

Tool untuk test koneksi dan authentication IMAP:

cd tools
go build -o imap-test.exe imap-test.go
./imap-test.exe <host> <port> <username> <password>

Contoh:

./imap-test.exe 10.10.11.30 993 info@trieltree.co.id P@ssw0rd123

Tool ini akan:

• Test koneksi SSL/TLS
• Tampilkan server capabilities
• Test berbagai format username
• Memberikan feedback detail untuk troubleshooting

Examples

Contoh Sukses Migration

# Single account
./mail-migrator --src "info@trieltree.co.id:P@ssw0rd123@10.10.11.30:993" \
                --dst "info@trieltree.co.id:P@ssw0rd123@10.10.11.24:993" \
                --insecure --log migration.log

# Output:
# ✓ Connected to 10.10.11.30:993 as info@trieltree.co.id
# ✓ Connected to 10.10.11.24:993 as info@trieltree.co.id
# ✓ Found 6 mailboxes to migrate
# ✓ INBOX: 17 messages migrated
# ✓ Migration completed successfully
