Topic: Can't send email with Thunderbird

[marsa_matruh]

I use SME Server 8.1, last updated mid July.

For years, I use thunderbird as email client with imap configuration.

Back from vacation, I can't send email with thunderbird. I get an error message (in French):

L'envoi du message a échoué.
Le message n'a pas pu être envoyé en utilisant le serveur SMTP « serveur.grenoble.sibert.fr » pour une raison inconnue. Veuillez vérifier que les paramètres de votre serveur SMTP sont corrects et essayez à nouveau ou contactez votre administrateur réseau.

SMTP settings are:

• Description : serveur
• Server name : serveur.machin.truc.fr
• Port : 465
• User name : my_account
• authentication method : normal password
• Connexion security : SSL/TLS

The only new thing is that I updated Thunderbird and now it is version 31.0. I'm not sure what was the previous version as I was using esr channel not so long time ago.

I can send email with webmail.

As you can send email with webmail, then there is unlikely to be any sme server problem.
I would be very carefully checking the Thunderbird settings, something has changed or there is a bug in Thunderbird.

Have you tried a different email client ?

Your certificate is changed and maybe you missed the request To accept the new one

[marsa_matruh]

So, I have looked at certificates. I found my server certificate under avast! Mail Scanner. I asked avast to not check outgoing emails. Then thunderbird asked me to validate my server certificate. The email was sent (and received). I turned avast back to scan outgoing mails. Cannot send email.

May be, the problem is with Avast, not thunderbird.

[Stefano]

if so, you should search on avast's site for a solution

Just a guess or hunch, maybe reinstall Avast, ie after the upgrade of Thunderbird.

[marsa_matruh]

Right now, I asked Avast not to scan SSL emails and I trust sme-server 

Maybe I have to reinstall Avast or find a way to reset parameters.
