🟠 [RGAA 11.2] Form labels are not relevant or explicit enough

[jbpenrath]

Bug Report

Problematic behavior
Some form labels do not convey enough information:

• Search filter labels are too vague ("From", "To", "In")
• Email field on the import page does not indicate expected format; file upload icon has screen reader text "inventory_2"
• "To" and "Copy" labels in the compose view lack format indication; explanatory texts are not programmatically linked
• "Default" checkbox label on the signature page is not explicit enough

Expected behavior/code
Labels must clearly describe the field's purpose, including expected format where relevant.

Steps to Reproduce

1. Activate a screen reader
2. Navigate through search filter fields — labels "From", "To", "In" do not convey enough context
3. On the import page, navigate to the email field — expected format is not indicated

Environment

• RGAA Criterion: 11.2
• Severity: 🟠 Major

Possible Solution

• Search filters: "From" → "Recipients"; "In" → "Message location"
• Import page email field: update <label>, e.g. "Email address – Expected format: name@domain.com"; remove "inventory_2" text from icon
• Compose view: "To" → "Recipients – Expected format: name@domain.com"; "Copy" → "Copy recipients"; include explanatory texts in <label> or via aria-description
• Signature page: aria-label="Set as default signature"
