Topic: Errore EHLO Thunderbird Aruba/TIM

[ginosapia]

Salve, dopo aver cambiato il vecchio router TIM e aver configurato il nuovo AG COMBO SMART sempre TIM non riesco più a inviare mail da Thunderbird.
Il messaggio di errore è il seguente:

«Si è verificato un errore durante l'invio della posta:
errore nel server posta in uscita (SMTP). Il server ha risposto: EHLO requires valid address»

L'ISP è appunto TIM mentre la casella postale è Aruba.
Sitema operativo Mac OS X 10.10.5.
Firewall disattivati.

Qualcuno potrebbe aiutarmi?
Grazie!

[ginosapia]

Ho provato tutti i settaggi di questo mondo, ma niente.
Attualmente il tutto è così impostato:

server:pop3.nomedominio.it
porta:110
STARTTLS
password normale

server:smtp.nomedominio.it
porta:587
password normale
SSL/TLS

[croma.to]

Prova usando smtps.aruba.it come server per la posta in uscita (al posto di smtp.nomedominio.it)

Spero sia utile

croma.to

[ginosapia]

Grazie croma.to, purtroppo non funziona.
Sospetto sia un probelma di autenticazione dei certificati di sicurezza,
ma quando tento di inserire un'eccezione mi dice:

«Nessuna informazione disponibile.
Impossibile ottenere stato dell'identificazione per questo sito»

Il bello che un altro Mac accanto al mio, settato in maniera identica, non ha nessun problema e invia regolarmente le mail!

[croma.to]

Cosa succede se, da Terminale, provi a dare questo comando openssl s_client -connect smtps.aruba.it:465 ?

Controlla anche quanto riportato in questa discussione

croma.to

[ginosapia]

Grazie croma.to
Confermo che si tratta di un problema di certificato:

Come posso risolverlo quindi?
Grazie ancora

[croma.to]

Dovrebbe mancarti il certificato relativo a GeoTrust Global CA

Puoi scaricarlo da questa pagina; è il penultimo della tabella Active Roots (GeoTrust_Global_CA.pem)

Una volta scaricato, rinominalo in .cer (quindi, da GeoTrust_Global_CA.pem a GeoTrust_Global_CA.cer).

A questo punto, per verificare se è questo il certificato mancante, ripeti il comando aggingendo -CAfile GeoTrust_Global_CA.cer

openssl s_client -connect smtps.aruba.it:465 -CAfile GeoTrust_Global_CA.cer

croma.to

[ginosapia]

Inserito il certificato i Thunderbird e ridato nuovamente il comando nel Terminale.

500 5.5.1 command unrecognized
Come posso procedere?
Grazie ancora

[croma.to]

L'opzione -CAfile GeoTrust_Global_CA.cer suppone che il file GeoTrust_Global_CA.cer sia nella directory dove esegui il comando

Se lo hai salvato in un'altra directory , devi inserire l'intero percorso per raggiungere il file (ad esempio, /home/GeoTrust_Global_CA.cer)

croma.to

PS. Riesci ad accedere al sito https://webmail.pec.it da firefox ?

[ginosapia]

Ho eseguito il certificato e la risposta è ancora negativa:
Gino:~ imacdigino$ /Users/imacdigino/Desktop/GeoTrust_Global_CA.cer
-bash: /Users/imacdigino/Desktop/GeoTrust_Global_CA.cer: Permission denied

PS
sì riesco ad accedere a https://webmail.pec.it/ da firefox

[croma.to]

il comando diventa:

openssl s_client -connect smtps.aruba.it:465 -CAfile /Users/imacdigino/Desktop/GeoTrust_Global_CA.cer
