Hello, updated from 3.4.1 to 3.4.3 and at the same time dovecot-2.2 to dovecot-2.3 ( + pigeonhole) I assume the changes behavior is dovecot/pigeonhole now using the advertised "CHUNKING" extension.
Now an echo service (dovecot-2.3-pigeonhole) don't send messages anymore. Reason: "Data command rejected: Multi-recipient bounce" while there is clearly only one recipient. the relevant debug logs: Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 220 signing-milter.org ESMTP Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: < signing-milter.org[84.200.211.109]: EHLO signing-milter.org Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250-signing-milter.org Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250-PIPELINING Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250-SIZE 128000 Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250-ENHANCEDSTATUSCODES Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250-8BITMIME Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250-DSN Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250-SMTPUTF8 Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250 CHUNKING Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: < signing-milter.org[84.200.211.109]: MAIL FROM:<> Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250 2.1.0 Ok Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: < signing-milter.org[84.200.211.109]: RCPT TO:<m...@example.org> Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: > signing-milter.org[84.200.211.109]: 250 2.1.5 Ok Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: < signing-milter.org[84.200.211.109]: BDAT 882 LAST Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: >>> START Data command RESTRICTIONS <<< Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: generic_checks: name=reject_multi_recipient_bounce Mar 11 23:27:54 dili postfix-smo/submission/smtpd[22427]: 44JCRG5tYPzCqt2: reject: BDAT from signing-milter.org[84.200.211.109]: 550 5.5.3 <DATA>: Data command rejected: Multi-recipient bounce;
