Hi
For test I use setup like haproxy + postfix - works fine via 587 /
587+tls and I have problem with 465
....
frontend ft_submission
bind 0.0.0.0:587
mode tcp
timeout client 1m
log global
default_backend bk_submission
backend bk_submission
mode tcp
timeout server 1m
timeout connect 5s
server postfix1 12.xxx.xxx.xxx:10587 send-proxy check maxconn 2000
weight 2
frontend ft_ssmtp
bind 0.0.0.0:465 ssl crt /etc/dovecot/ssl/cert.pem
mode tcp
timeout client 1m
log global
default_backend bk_ssmtp
backend bk_ssmtp
mode tcp
timeout server 1m
timeout connect 5s
server postfix1 12.xxx.xxx.xxx:10587 send-proxy check maxconn 2000
weight 2
# server postfix1 12.xxx.xxx.xxx:10465 send-proxy check maxconn 2000
weight 2
.....
master.cf:
10587 inet n - - - - smtpd
-o syslog_name=postfix/submission-haproxy
-o smtpd_upstream_proxy_protocol=haproxy
10465 inet n - - - - smtpd
-o syslog_name=postfix/smtps-haproxy
-o smtpd_upstream_proxy_protocol=haproxy
If I testev via:
openssl s_client -connect haproxy.domain.ltd:465 -crlf
works fine after AUTH LOGIN etc
If i test via swaks
1)swaks --auth LOGIN --server haproxy.domain.ltd --port 587 --to
us...@domain.ltd --from us...@domain.ltd --auth-user us...@domain.ltd
--auth-password ..... --tls ------ works fine
2)swaks --auth LOGIN --server haproxy.domain.ltd --port 465 --to
us...@domain.ltd --from us...@domain.ltd --auth-user us...@domain.ltd
--auth-password ..... --tls
i get only:
=== Trying xx.xxx.xxx.166:465...
=== Connected to xxx.xxx.xxx.166.
If i try
swaks --auth LOGIN --server haproxy.domain.ltd --port 465 --to
us...@domain.ltd --from us...@domain.ltd --auth-user us...@domain.ltd
--auth-password ..... --tlsc (--tls-on-connect)
connect ok end sending e-mail
but not then any smtp klients like thunderbird
and nothing
If I try send e-mail via 465 via thunderbird - trying and trying and
nothing
Where i find the problem ? Certyfikat is correct
