    Hi Forum.
    Using Latest WordPress I’m experiencing some troubles using a external mailserver directly ( changed after beeing hacket a few times)

    Normally I’m using port 587 with authentication.
    But whenever/whatever I’m trying – I’m getting this error:

    connect from SERV02.lan[172.16.10.110]
Jul 28 17:04:18 serv01 postfix/smtpd[9481]: SSL_accept error from SERV02.lan[172.16.10.110]: 0
Jul 28 17:04:18 serv01 postfix/smtpd[9481]: warning: TLS library problem: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:s3_pkt.c:1294:SSL alert number 48:
Jul 28 17:04:18 serv01 postfix/smtpd[9481]: lost connection after STARTTLS from SERV02.lan[172.16.10.110]

    Thats even when no encryption selected – So what causing this problem and howto fix it

    What plugin are you using to tie into an external mailserver? If it’s not modified with a plugin, WordPress can only use PHP’s mail() function, which uses the local mailserver.

    I’ve actually tried a coouple – but still gets the same error ( no problems from m y Concrete5 sites)

    I’ve tried the following plugins:
    WP Mail From II
    WP-SMTP-MAIL-CONFIG
    WP-Mail-SMTP

    But no luck getting the mail send through external mailserver

    Are you using the latest openSSL libraries on your server? It appears that there’s an issue with the TLS connections. This is a server configuration issue.

    I asked whether the latest libraries were installed; I suspect that you’re using either an old version or accepting now invalid protocols, but this is not a WordPress issue. It’s a sysadmin thing.

    I agree with Steve, this is not a WordPress problem, so there isn’t much we can help with here. I recommend contacting your hosting provider’s support.

    Do you mean https://wordpress.org/plugins/postman-smtp/ ? If so, I suggest you continue to use it. It’s quite good.
