[Mailmunge] MTA Macros

[postfix at ptld.com]

I tried using /etc/default/mailmunge:MM_EXTRA="-a tls_version"
Still got UNDEF.

Noticed there is also "-a socket MX_UNPRIV_SOCKET=socket" for 
mailmunge-multiplexor.
Checked logs, when using MM_EXTRA="-a tls_version" i get this error

    mailmunge[10767]: NOQUEUE: MXCommand: connect: No such file or 
directory: Is multiplexor running?

I assume some kind of conflict is happening between the -a for mailmunge 
vs the -a for mailmunge-multiplexor when using default file.
Is there a way to work around this while still using the default file?
