Packet capture required for further diagnosis.
Small remark. The session log is: SMTP>> MAIL FROM:<**DELETED**> SIZE=151847 SMTP>> RCPT TO:<**DELETED**> will write message using CHUNKING SMTP>> BDAT 7789 SMTP<< 250 2.1.0 OK t18si12300997ejj.437 - gsmtp SMTP<< 250 2.1.5 OK t18si12300997ejj.437 - gsmtp SMTP<< 250 2.0.0 OK t18si12300997ejj.437 - gsmtp SMTP>> BDAT 143035 LAST BDAT sizes are 7789+143035=150824, but MAIL FROM contains SIZE=151847. They should be equal, isn't it? And there is no reply from server to BDAT LAST, that is also strange. Packet capture would be very helpful, yes. -- Eugene Berdnikov -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
