Could you please open a Support ticket for this?  There may be some settings that we can add in server.properties to get this working for you. You can also test this from the command line with the following:

/opt/arcsight/manager/bin/arcsight emailsetuptest -s <SMTP_SERVER> -u <USERNAME> -p <PASSWORD> -to <TO_ADDRESS> -protocol <PROTOCOL> -servertype 2

Hi Dale,

Thank you for your feedback.
indeed my support has expired.
I use the Kaspersky gateway, with this gateway the username and password are not required, is it possible to configure emails without authentication?

I could have sworn the answer to this was yes, but according to the documentation, no.

Notification
Fields Definition
From
Address
The e-mail address from where the notification messages are sent. It is important that the
"from address" specified is one that is not rejected by the SMTP server, since some SMTP
servers reject unknown e-mail addresses. For notifications sent by cell phone, any cell
phone must be e-mail enabled.
Outgoing
Mail Server
The host name of the local outgoing mail server. This is the SMTP server ArcSight uses to
send e-mail. The Outgoing Mail Server must be accessible from the ArcSight Manager for email
notifications to be sent. SMTP is used to send e-mail. An SMTP server must be
configured either at install time or set here.
Incoming
Mail Server
The local incoming mail server host name.
Incoming
Mail
Protocol
Select either IMAP or POP3 mail protocols.
E-mail
Account
The e-mail account name. For notifications sent by e-mail, you need to add an address to the
e-mail Address field.
Account
Password
Enter the password for the account.
Confirm
Password
Re-enter the same password to confirm.
Note: POP3 and IMAP can be used to check for e-mail acknowledgments. You can specify
these options at install time, or set them here. For acknowledgements, the relevant fields
are "incoming mail server," which is the POP/IMAP server to specify to check e-mail,
"incoming mail protocol," which is either POP3 or IMAP, "account" and "password," which
are the login name and password to access the mailbox from the incoming mail server.
Note that replying to mails from the notification "from address" should reach the mailbox
accessible to the "account" login.

What version of ESM is this?  If you would like to renew let me know who your Sales Rep is and I will be glad to get you in contact.

I would add that if you use built-in notification then you are not prompted for authentication, but you have less flexibility on configuration options.

Thanks for the enlightenment,

I use version 7.6 and on the kaspersky gateway It's not possible to create username and password, just authorize Host IPs and that's it.

I even tried emails which are quite functional.

Thanks anyway, I'll see

Best Regards
