Hi @Amolowe2021

I’ve read your SMTP config section from the other thread and you could try adjusting the smtp_auth parameter from ssl to tsl as this user did:


thank you what i latter did is i got myself a third party SMTP provider Sendpulse to be precise and it works, originally webmail cant send more than 300 mails per month but with sendpulse i have 12000 mails per month, thanks
