webmail.pttdp.com:143 STARTTLS, sebelumnya pakai SSL Cert yg lama
tidak ada masalah
Sepertinya port 143 (IMAP/TLS) terfilter SSL/TLSnya.
Periksa setting firewall.
$ openssl s_client -starttls smtp -connect webmail.pttdp.com:143
CONNECTED(00000004)
Didn't find STARTTLS in server response, trying anyway...
$ openssl s_client -starttls smtp -connect webmail.pttdp.com:587
