We have the same setup, but with a more recent postfix and OS. Shouldn't matter that much. So I went looking for similar log entries in my old logs: Aug 27 11:44:28 mail postfix/smtp[16154]: 3X57Tg6GwvzCsRj: lost connection with s-mx14-ht01.charite.de[10.32.37.105] while receiving the initial server greeting but then the 2nd internal MX was used (exchange.charite.de has two MX hosts, pointing to the two hub transport servers). Sep 19 11:06:04 mail postfix/smtp[18775]: 3XMFY40JJzzCrvh: lost connection with s-mx14-ht01.charite.de[10.32.37.105] while receiving the initial server greeting and again, the 2nd internal MX was used. So, it's happening here as well. Twice in 4 weeks. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebra...@charite.de | http://www.charite.de
