Unable to connect to SMTP server

  • 1.  Unable to connect to SMTP server

    Posted 02-19-2019 05:03 AM

    Hi, everyone.

    I encountered the following the error "Couldn't connect to the SMTP server using the specified settings. Please re-enter the SMTP settings." when entering the SMTP setting in the General Settings on Enforce console.

    However, the settings are properly entered and I can log into Exchange OWA using the credentials. I am also able to telnet to the SMTP server via port 25.

    FYI,

    Server: 172.27.10.75

    System Email: dlp.mail@example.com

    User ID: example\dlp.mail

    Password: ********

     

    I need urgent solution on this.

    Hi Pan Fei,

    What is the DLP version on which you are facing this issue ? Also share the OS details for Enforce and SMTP (Detection server ).

    If it's 15.1 , We will need to follow below :

    Stop all DLP Services on Enforce Box

     

    On the 15.1 Enforce install, remove both mail-1.4.7.jar and javax.mail1.6.0 jar from the following directories:

     

    <DLP_home>\Server Platform Common\15.1\Protect\lib\jar

    <DLP_home>\Enforce Server\15.1\Protect\tomcat\lib

     

    Place the mail.jar in the below location

    <DLP_home>\Server Platform Common\15.1\Protect\lib\jar

    <DLP_home>\Enforce Server\15.1\Protect\tomcat\lib

     

    Start all the DLP Services on Enforce Box

    Hello Ridhi,

    I am seeing the same issue in 15.5 would you know if its the same fix? Where can I locate the needed replacement files, I reached out to support but, still waiting for any response.

    Thanks for any direction, hoping the files are available to download from somewhere within my account

    Hello Fady,

      As of version 15.0, Symantec Data Loss Prevention no longer supports anonymous logins to the SMTP server that is used for sending out alerts and reports. You must enter a valid user name and password.

    Trying to upload mail.jar file but it is not uploading here.
