No mail are sending anymore and i don't know why

Post by Fabio51 »

Hello People,

I use Mantis on a Windows Server with WAMP since 2016.

Since a few day, mail doesn't sent anymore despite we didn't change anything on this server.

I look a lot of help about this issue, even guides who are posted there (viewtopic.php?f=3&t=15398) ....No solutions.

Some informations :

- We use SMTP on port 25 (no SSL, no TLS).
- ssl_module and php_openssl are enabled.
- If i try to send email by a SMTP sample test programm (C#), the mail is sended and received...(so my SMTP is OK).

If i enable the log, i get :

04-03-2020 15:18 mail Processing e-mail queue (2568 messages)
04-03-2020 15:18 mail Sending message #104308 queued on 20-02-2020 23:40
04-03-2020 15:18 mail ERROR: Message could not be sent - SMTP Error: Data not accepted .<p> SMTP Error : 2.1.5 Ok
</p>

I tried to use the test_email.php but i get php error :

Do yo have some idead ? Some things to try ?

Thanks a lot,
cas
