Send e-mail node - no communication with smtp server

[Veronika_Eder12]

Good Evening,
I’m realtively new to knime, trying to fight my way in

I am currently trying to send serial e-mails with the node “wait” in order to fix the time and “send e-mail”.
Unfortunatelly I get the following error from the “send e-mail” node:
Error while communicating with the smtp server:javax.mail.MessagingException:Could not connect to SMTP Host

I tried my gmail and my outlook account and activated the IMAP on each of them.

Could someone please help me? Thanks a lot!

Hi @Veronika_Eder12 -

How is your Send Email node currently configured? I was able to send myself an email via my Gmail account just now using the following settings:

Hi Scott, thank you for your quick answer, it works now.
The problem was that my mail account classified kime as insecure - I deactivated that an now it works.

Have a nice day!
