Okay, I'm made some exciting progress and I am grateful for the help. I will show to people how I got this working At first thought, I figured that it would simply be the IMAP password used by Dovecot to access my mailbox. Not exactly true... I did some digging in some blogs and the

Texto em portugues: Pelo que eu entendi você está com problemas para enviar e-mails partindo do thunderbird; não sei se compreendi o motivo do teste de DNS mas me parece que você quer confirmar o MX. Em geral a porta segura do SMTP é a 465, o gmail utiliza a 587. Utilizando a lógica seu dominio

Okay, Victor, thanks for the stats in the second email! That is quite interesting to read. I have only recently (this summer) heard of LetsEncrypt.org. Up until that point, I had expected that I was condemned by powers-that-be to buy a key annually forever. Oh yeah, I love the "smoke and

I should make clear in the post that u...@example.com is the IMAP mailbox name and that m...@example.com is a virtual alias. This machine hosts about 8 domains and has, I think, three mailboxes. I am the sole user of the email system. On 11/28/2016 at 11:58 AM, rich.gre...@hushmail.com wrote:

Hello, First, email has been working fine on this server for past several months while using the Squirrelmail web client located on the same server. I am needing an alternative method to access mail services and decided, on a whim, to try Thunderbird. Thunderbird interacted with the Dovecot
