Unfortunately it occurs just every once in a while and it is weird because at the second attempt the message is successful delivered or redirected. >>> Also, I don't see anything weird in the PCAP files: the command-reply >>> sequence is OK.

Ok I'm agree! So, about you, which version can I try to install the 2.2.27 or the previous release of the 2.3 version such as v2.3.2 2018-06-29 or v2.3.1 2018-02-29?
