BIRD mailing list issue - root cause found: BIRD MTA fails to resend after being greylisted

10 Oct 2019

      Hi,

the root cause for the mailing list issues have been found.

trubka.network.cz gets greylisted by never tries to delivery the emails
again.

{{ Oct  4 13:17:46 mx2 postgrey[1652]: action=greylist, reason=new,
client_name=trubka.network.cz, client_address=2001:1568:b:145::1

Could you look into your MTA configuration to resolve this issue?

thanks,
Christoph
