🚀 go-pugleaf

Skonfigurowałem Postfiksa z uwierzytelnianiem SASL, ale coś nie chce działać wysyłanie maili.
Sprawdzanie telnetem daje taki wynik:

telnet localhost 587
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
EHLO localhost
Connection closed by foreign host.

I tyle. Natomiast na port 465 jest już inaczej.

telnet localhost 465
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 mail.moja.domena.pl ESMTP
EHLO localhost
250-mail.moja.domena.pl
250-PIPELINING
250-SIZE 128000000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH PLAIN LOGIN
250-AUTH=PLAIN LOGIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-DSN
250-SMTPUTF8
250 CHUNKING
quit
221 2.0.0 Bye
Connection closed by foreign host.

Klient skonfigurowany do wysyłki na port 465, wysyła i maile dochodzą.
Niestety, obawiam się, że serwer jest open relay.

Mój wynik postconf -n

W maillog mam taki pojawiający się dość często komunikat:

SSL_accept error from gate[192.168.0.253]: -1
warning: TLS library problem: error:14095126:SSL routines:ssl3_read_n:unexpected eof while reading:ssl/record/rec_layer_s3.c:302:

Co mogłem zepsuć?
