[Pkg-mailman-hackers] Bug#718284: postfix-to-mailman: can't run genaliases properly (maybe doc bug?)

[Daniel Pocock]

Package: mailman
Version: 2.1.15-1


I'm trying to use postfix-to-mailman.py

According to the instructions in the script itself,

a) I should set MTA=None
b) I should run "genaliases" to generate the data/virtual-mailman file

However, when I set MTA=None, I get this error from genaliases:

"genaliases can't do anything useful with mm_cfg.MTA = None"

If I set
  MTA = 'Postfix'

then the virtual-mailman file is generated correctly.

If I understand correctly, the presence of the virtual-mailman is not
essential, but if it is present, then Postfix can reject (rather than
bouncing) mail to unknown lists and avoid backscatter from spam.

Can somebody please clarify if this virtual-mailman file is still
supported?  Or should the instructions in the script be changed to
remove references to genaliases?
