<code>penelope.mailbox.showLines.color</code>
* Default: '''#C0C0C0'''
* This preference controls the color of the mailbox grid lines in a mailbox table of contents.* Named Visibility of the lines is controlled by '''[[Documentation Conventions and Nomenclature|[Options/Prefs window]]] > Extras >''' '''''Mailboxes''''' : ''Show mailbox lines''.* The column dividing lines are drawn on the right sides of the columns. The first three default columns in Eudora OSE are ''Status'', ''Priority'', and ''Attachment''. As with the classic app, they are specifically drawn so that they do not have column dividers. Unfortunately, unlike classic Eudora there is no logic in the interface to compensate and draw in the missing lines if you decide to move those columns to an other than default order.* Acceptable formats: RGB hex triplets or HTML colors can also be usedcolor names.* Trivia: the default grey line color is the same as it was in classic Eudora.* To replicate cE’s BlackTocLines setting, use '''#000000''' (or '''black''').
