I frequently have to send e-mails from different addresses, so it seems I need to have manage multiple .conf files for this to work correctly? Example: - login user: example@example.com - alises: *@example.com, postmaster@example.com, abuse@example.com ... Mail addressed to "ex@example.com" is delivered to "example@example.com" inbox. But instead of replying from "example@example.com", I would prefer to reply via "ex@example.com" Thunderbird offers the feature to modify the "from" header for each mail (which is nice). So I am curious how I would be able to do this with Aerc without having to constantly fiddle with the configuration files (ie, create new conf, add conf entry, ...)
