What sequence of actions has to be taken in order to configure DB2 UDB SMTP mail?

I read https://www.ibm.com/support/knowledgecenter/SSEPGG_9.7.0/com.ibm.db2.luw.sql.rtn.doc/doc/r0055176.html and tried to run the command provided in the article, even though I fully expect SMTP to not work because my server requires a user name and password authentication that the command is missing.

So, just to try it out, I fired off:

db2 update db cfg using smtp_server 

It threw this error:

SQL1024N  A database connection does not exist.  SQLSTATE=08003 

Are there any prerequisites to the above command that I am missing?

And once we get this to work with the community’s help, how are we supposed to provide user name and password for the SMTP server in DB2 UDB?

Is it possible to configure SMTP relay on SSRS 2012 RTM?

I am trying to configure SSRS 2012 RTM to work with user and password to a remote SMTP server. In 2016 its working just fine but for some reason on 2012 it doesn’t- when i add the SMTP configuration below and then i try to create an SSRS subscription it will not allow sending subscriptions that are not file share subscriptions. IS this feature supported in 2012? (SMTPAuthenticate= 1)

configuration file SMTP setup: enter image description here

I also checked the error logs and could not find an error. Thanks In advance

Configure SMTP Server to send mails through different other SMTPs [closed]

i’m tring to install a smtp server which uses randomly other smtp-servers to send emails. Here is an example setup:

if a email is send using smtp1.domain.de the smtp server will look in a list or something and select one of the smtps provided there with domain email and password. For example:

smtp2.domain.de smtp3.domain.de

It would be nice if the select process is scriptable with python or something or may be completly random.

Thanks for your help.

Securing SMTP server and its logs

Looking for general mail server security best practices here.

I did some research and it’s really hard to find the information out there.

  1. How do you safe guard a smtp server log? Are there any encryption tools out there? Our reason is if the server is compromised, at least the logs are not in plaint text format for attackers to see without obtain our tool/keys.

  2. It seems like most SMTP servers out there stores recipient information in the log files, how can we ensure these information are not stored or at a minimum are scrambled. Is that possible?

Thank you and I’m still researching on the subject.

HOWTO: Install/Configure msmtp and mutt on ubuntu

I got GTS CA 1O1 as the common name instead of Google Internet Authority G2. What is the difference between the two.

So GTS CA 1O1 refers to the one listed here https://pki.goog/?

I see GTS CA 1O1 valid until Dec 15, 2021. So by Dec 15, 2021, I should regenerate the local crt file by openssl x509 -inform DER -in GTS1O1.crt -outform PEM -out gmail-smtp.crt
