Yes, postfix 3.6 didn't trigger my problem. But I wonder, if that the simultaneous upgrade of the openssl package might be the cause of postscreen's dying after that "TLS random garbage" problem? See, from another mail of mine: | 2022-03-17 changes in jail mail: | | -openssl-1.1.1m_2,1 TLSv1.3 capable SSL and crypto library | +openssl-1.1.1n,1 TLSv1.3 capable SSL and crypto library | +pcre2-10.39 Perl Compatible Regular Expressions library, version 2 | -postfix-3.6.3,1 Secure alternative to widely-used Sendmail | +postfix-3.7.0_1,1 Secure alternative to widely-used Sendmail Please let me know, if there is anything I can do to investigate from my end? Thanks in advance and with kind regards, Michael
