WorldClient and aliases

Did you know WorldClient has support for aliases?

Go create an alias (without wildcards), then hit the compose button in WorldClient and note that the FROM field is now a dropdown — You can choose to send mail using any alias which points to your mailbox.

Even better, when you reply to a message, WorldClient will automatically choose the alias to which the original message was addressed.

There is also a hidden INI switch that can influence this behavior,

WORLDCLIENT.INI, [Special] section.
UseFirstAlias=No (or Yes)

If this is set to yes, WorldClient will always use the first alias which applies to a mailbox (not counting wildcard aliases) rather then guessing at which alias is most appropriate.
