At present option smtpchk closes the TCP connection abruptly on completion of service checking, even if successful. This can result in a very high volume of errors in backend SMTP server logs. This patch ensures an SMTP QUIT is sent and a positive 2xx response is received from the SMTP server prior to disconnection. This patch depends on the following one: * MINOR: smtpchk: Update expect rule to fully match replies to EHLO commands This patch should fix the issue #1812. It may be backported as far as 2.2 with the commit above On the 2.2, proxy_parse_smtpchk_opt() function is located in src/check.c [cf: I updated reg-tests script accordingly]
