How to solve ActiveRecord::ValueTooLong error when using ActionMailbox?

I'm using ActionMailbox in my Rails 7 project to receive inbound emails. I followed the configuration and migration setup as outlined in this guide. The email reception is functioning correctly with Postfix, and the connection is established.

However, from time to time, I encounter the following exception:

ActiveRecord::ValueTooLong in Rails::Conductor::ActionMailbox::ReroutesController#createMysql2::Error: Data too long for column 'message_id' at row 1

Upon inspecting my schema, I found that Rails created the following table for ActionMailbox::InboundEmail:

create_table "action_mailbox_inbound_emails", charset: "utf8mb4", collation: "utf8mb4_0900_ai_ci", force: :cascade do |t|  t.integer "status", default: 0, null: false  t.string "message_id", null: false  t.string "message_checksum", null: false  t.datetime "created_at", null: false  t.datetime "updated_at", null: false  t.index ["message_id", "message_checksum"], name: "index_action_mailbox_inbound_emails_uniqueness", unique: trueend

I'm considering a few potential solutions:

Increase field size: Since this is a built-in Rails feature, I'm hesitant to add a new migration to increase the field size.

Custom model: Another option is to create a custom CustomInboundEmail model that inherits from InboundEmail and enforces a limit of 255 characters for the message_id. However, this approach may be risky as it could interfere with existing logic, such as maintaining uniqueness or other constraints.

Do you have any other ideas or suggestions?
