Mailer does not work
We compiled from source haproxy-1.6-dev2.tar.gz. New Mailers mechanism does not seems to work, we configured as on manual: mailers apsmailer1 mailer smtp1 :10025 ... ... backend somebackend_https mode http balance roundrobin ... email-alert mailers apsmailer1 email-alert from email-alert to email-alert level info ... We see in haproxy.log server status change: Jul 15 09:42:00 localhost.localdomain haproxy[3342]: Server .../ is UP, reason: Layer4 check passed, check duration: 0ms. 2 active and 0 backup servers online. 0 sessions requeued, 0 total in queue. Jul 15 09:42:00 localhost.localdomain haproxy[3342]: Server .../ is UP, reason: Layer6 check passed, check duration: 1ms. 2 active and 0 backup servers online. 0 sessions requeued, 0 total in queue. But no mail alerts are sent, no error or warning logged about sending mail. haproxy -f /etc/haproxy/haproxy.cfg -c does not return any error. All seems to be right, but mail alerts are not sent.

RE: Mailer does not work
We take a tcpdump. Following the tcp traffic we can see each step. Reproducing manually the mail was sent. Probably HAProxy SMTP communication has an error on the final stage . as of that all goes right. Follows manual communication with mmail server reproducing tpcdump smto command seguence.

Re: Mailer does not work
It looks to me as if the dot is send in the wrong place. Attached patch would fix that. https://www.ietf.org/rfc/rfc2821.txt the character sequence "." ends the mail text.
