Hi,

Strange problem, e-mail messages I try to send are not reaching receiver server. These are my logs.

Code:
2017-10-19 07:22:56 1e58ue-0002IN-DR <= [email protected] H=bth41.neoplus.adsl.tpnet.pl ([192.168.0.12]) [83.29.153.41] P=esmtpa A=plain:[email protected] S=887 [email protected] T="Testing message" from <[email protected]> for [email protected]

I am also getting return message like Mail delivery failed: returning message to sender with status 5.0.0 on senders mail dominik[at]zencore[dot]pl.

On receivers server there is no information (in logs) that I send them any message or my server tries to connect to thems.

There is no problem with sending emails to other domains on same server, or gmail accounts. What can we do to make it work?
