ImapSync List

A Bash wrapper around imapsync that batch-migrates IMAP mailboxes from a list of accounts stored in a CSV/pipe-delimited file.

Features

• Syncs multiple accounts in sequence from a single accounts file
• Writes per-account log files and an aggregated master.log
• Stores passwords in temporary files (never passed on the command line) and removes them after each sync
• Reports a summary of failed accounts at the end
• Terminal summary listing any accounts that failed

Requirements

• imapsync must be installed and available on $PATH

Usage

./imapsync-list.sh -s SRC_HOST -d DST_HOST -f ACCOUNTS_FILE [-l LOG_DIR]

Flag	Description	Required
-s	Source IMAP hostname	Yes
-d	Destination IMAP hostname	Yes
-f	Path to the accounts file	Yes
-l	Log output directory (default: ./logs)	No

Accounts File Format

One account per line, pipe-delimited:

email@example.com|password123
another@example.com|s3cur3pass
# Lines starting with # are ignored

CSV files in the csv/ directory follow this same format.

Example

./imapsync-list.sh \
  -s mail.source.com \
  -d mail.destination.com \
  -f csv/example.com.csv \
  -l logs_example/

Notes

• Both source and destination connections use SSL (--ssl1 --ssl2)
• Duplicate messages on the destination are removed (--delete2duplicates)
• Folder size calculations are skipped for speed (--nofoldersizes)

Those can be modified in the script if needed. Always test with a single account first to ensure the desired behavior before running a full batch.
