[MM3-users] Re: localhost[::1] said: 550 Requested action not, taken: mailbox unavailable

Hi,

We need more information.

What are the postfix log messages associated with the error?

Oct 27 08:24:58 srv20 postfix/lmtp[2981]: 8798E40979: to=<admin@lists.ffnw.de>, relay=localhost[127.0.0.1]:8024, delay=0.51, delays=0.43/0.02/0.02/0.03, dsn=5.0.0, status=bounced (host localhost[127.0.0.1] said: 550 Requested action not taken: mailbox unavailable (in reply to end of DATA command)) Oct 27 08:24:58 srv20 postfix/cleanup[2980]: 02C694097E: message-id=<20171027062458.02C694097E@mail.ffnw.de> Oct 27 08:24:58 srv20 postfix/bounce[2982]: 8798E40979: sender non-delivery notification: 02C694097E

Is the list's domain the same as the working ones?

Yes.

Are there entries for the list in Mailman's var/data/postfix_lmtp?

Yes.
