suppressing the main email account and displaying the aliases

suppressing the main email account and displaying the aliases


I prefer to email through my aliases rather than the main account name. Is there a way to suppress the main account's email address in the From field dropdown and only display the aliases when composing a new email?

for example, if i have Mark_Porter@email.com as the main account and i have two aliases: MPorter@email.com and Mark@email.com . I never use Mark_Porter and would like to suppress it. That way, i never choose it by mistake.

Thanks!
