    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???

    Regards,
    Raman

    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,
    T=DNS/RFC822/SMTP,
    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
