Your openssl-3.0.9 (I suppose gentoo stable?) will not allow TLSv1 or sslv3 connections bei default anymore. Wild guess: you need to explicitely allow for example DEFAULT@SECLEVEL=0 ciphersuite in postfix to make *your* openssl accept this remote sslv3 connection Cheers -Marc -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Schleißheimer Straße 26/MG, 80333 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer, Wolfgang Stief Aufsichtsratsvorsitzender: Florian Kirstein _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org
