Seafile Problem with sending external email

Good morning,

we have a problem with the seafile server, we have configured the parameters for sending emails and with internal mails function very well, but when we try to send an email to the outside we receive an error.

“internal server error, but check the inserted emails”

the mail is correct because from the outlook client the mail arrives, can you tell me where to go to read some logs?

Greetings,
Mirko stefanelli

Whar about seafile.log?
