[Mailman-Users] Unable to post to list (Mailman+Exim)

[Kapil Karekar]

Hi,

When I post to a newly created list I get the following error:

--------------------------------------------------------------

<listname at lists.domain.tld>: host lists.domain.tld[xxx.xxx.xxx.xxx] said: 550
    Unrouteable address (in reply to RCPT TO command)

--------------------------------------------------------------

How can I avoid this issue without having to add new aliases for each
list in /etc/aliases?

I am using Exim as the MTA.

Thanks in advance :-)

p.s. I am a newbie to both exim and mailman.
