Hey everybody,
I want to use mailjet.com (Free-Account) as SMTP-Relay.
As SMTP-Credentials I use:
in-v3.mailjet.com:587
API KEY + API SECRET
(here: https://documentation.mailjet.com/hc/en-us/articles/360043229733-Why-am-I-getting-a-Relay-Access-Denied-error-when-using-SMTP-relay-)
If I use these settings in thunderbird and configure an SMTP-Server the emails are send perfectly.
If I create a “Sender-dependent transports” and then assign this relay to a mailbox the mails are not send through. The test of the Relay is working fine but as soon as I send a mail it return this error.
example@example.com: SASL authentication failed; server
in.mailjet.com[104.199.96.85] said: 535 5.7.8 Error: authentication failed:
The strange thing is that I do the same with sendinblue and this is just working fine.
Does anybody has some experience with mailjet?
Best regards
Christoph
