<p dir="auto">As I manage my own domain name I'm able to make-up mail addresses to match the group or organisation I'm dealing with whenever I'm asked to provide one.</p>

<p dir="auto">Mail to these addresses all ends up in the postmaster account unless I generate a forwarding rule. I usually reserve that action for forwarding them to /dev/null when the organisation becomes annoying.</p>
<p dir="auto">That works perfectly for receiving mail. However, when I reply to mail the FROM field is postmaster@ rather than my whatever_lol@ not-an-email address.</p>
<p dir="auto">I'd really like to have some way of auto populating the From or the Reply-to field without having to remember to use the Customise option.</p>

<p dir="auto">I've been using unique email address for each group or business. My mailserver is set to deliver all mail with an unknown recipient address to my main account, and I use MailMate rules to move messages into different physical mailboxes. When I reply to a message, MailMate is smart enough to find the recipient address that matches my email pattern in the account settings[1], and use that address as the "From" address. In the fairly rare case where it doesn't use the right address, I use the drop-down control in the "From" field of the composition window to edit it.</p>
<p dir="auto">[1] In the settings of each account is an "Email Address(es)" field. Put your most commonly used addresses there (as this is used to initially populate the "From" drop-down). Use a comma to separate addresses. Below the "Email Address(es)" field is an "Address Pattern" field with a checkbox. Check the box and fill in a pattern to identify your email addresses (e.g., "*@businessdatasystems.co.nz" (without the quotes) to match anything @businessdatasystems.co.nz). If you use multiple domains, you can have multiple patterns, e.g.,:</p>
