email sent and not received

[gianfranco]

Hi Stefano,
on WordPress 3.3.2 I manage Newsletter plugin v.2.5.2.6 with a mailing-list of 5031 subscribers. Sometimes a big part of subscribers do not receive newsletter despite the email status showing “sent” to all.
How come?
Thanks

Hi Stefano,
i tried to send newsletter to single lists with max 1000 accounts. Also this time some subscribers did not receive email despite the email status showing “sent” to all.
N.B. I set ‘Max email per hour’ to 500 (provider limit is 800).
Tnx a lot

The plugin delivers emails to your mail server. If the mail server dorps them, no one will be notified. You should ask confirmation from your provider about emails per hour limits and if they can check while email are not delivered looking at the mail server logs.

Which is your provider? Have they a page where they wrote the emails per hour limit?

Hi Stefano,
Aruba told it is not possible to check server logs, limit is 700/800 emails per hour.
Thanks

Aruba… un disastro! Hai anche la posta elettronica con loro? Se sì prova ad usare i loro dati SMTP anche con la newsletter. Oppure fatti un account free su mailjet o mandrill per prova e usa il loro SMTP per vedere se con quelli riscri a spedire (non servono le estensioni, bastano i parametri SMTP da inserire nella configurazione principale).

[gianfranco]

si, anche la posta.
nella configurazione principale della newsletter, dove vanno inseriti i parametri SMTP?
grazie mille!

Nel pannelo dell’smtp…

[gianfranco]

Grazie Stefano, avevo una versione che non contemplava il pannello smtp.. 😀
Per il momento ho solo abilitato l’smtp e inserito come host smtp.aruba.it. Non so come riempire tutti gli altri campi. Comunque ho fatto un test con la mail sender della newsletter, e mi ha restituito un “Success” con questo esito che ti allego qui sotto (scusa in anticipo nel caso la cosa fosse eccessiva).
Non devo fare nient’altro? Grazie.

Ciao Stefano, dopo le modifiche effettuate, e numerose prove di invio, sono certo che, al momento, nessuno degli account riceve la newsletter. 🙁

[Stefano]

Guarda, fatti un account free su mailjet, ti daranno i loro dati SMTP. Li provi dal tuo sito e se funziona allora è un problema dell’SMTP di aruba.
