    Hi All,

    I am trying to configure SMTP client my linux machine, where i will be using external SMTP server for oubound mail.
    I have added below line in my sendmail.mc and create sendmail.cf using m4.
    define(`SMART_HOST', `my.host.com')dnl
    define(`confCACERT_PATH', `/etc/pki/tls/certs')dnl
    define(`confCACERT', `/etc/pki/tls/certs/ca-bundle.crt')dnl
    define(`confSERVER_CERT', `/etc/pki/tls/certs/sendmail.pem')dnl
    define(`confSERVER_KEY', `/etc/pki/tls/certs/sendmail.pem')dnl
    define(`confCLIENT_CERT', `/etc/pki/tls/certs/sendmail.pem')dnl
    define(`confCLIENT_KEY', `/etc/pki/tls/certs/sendmail.pem')dnl
    DAEMON_OPTIONS(`Port=465, Name=TLSMTA, M=s')dnl

    but i could see still the request going on default port 25. How can i send forward it through port 465.

    Further do i need to make any configuration changes in submit.mc???

    Hi all,

    This is inform that the above issue is fixed after adding 465 in submit.cf at the end of Mrelay Tag:

    Mrelay, P=[IPC], F=mDFMuXa8k, S=EnvFromSMTP/HdrFromSMTP, R=MasqSMTP, E=\r\n, L=2040,
    A=TCP $h 465

    But now i m not getting client greeting and connection getting timeout.

    Just to inform you when i am using other client like thunderbird i am able to send mail with the same configurations.

    Please suggest/help to fix this issue
