pedrofigas SMTP & IMAP problems SOLVED
Email already fixed, after spending hours of reading and testing I still don't know what was causing this, the only thing I, ve done was to enable SSL on Mail Server waited a few minutes and started to work (although a bit slow), I was relying on the SMTP and IMAP test tools that still are shooting errors, authentication errors (don't know why) but the most important thing is that I got this running.
Has for SOA values it's another story but I think they are set correctly.
So after talking with my hosting and domain company I, ve found that each one said that they can't do anything and, this got me looking for answers online and I have found a problem like mine but with a respected website, where there are many devs talking about pretty much everything.
If you have 5 min you can check this website https://bit.ly/2Pafwcz and skip to almost the end, where is this guy who seems to understand very well about SOA values and DNS (like you), and he said that most of DNS check websites are misinformed about how SOA values work, and many of them copy past results from each other.
He recommended a respected website on this regard Mxtoolbox.com, I followed his link made a DNS check including SOA, check out the results for my website https://bit.ly/2DosErP... To be honest, after seeing this, I'm done!
So thank you very much for your help, patience, and understanding, was very much appreciated.
Grande Obrigado e Abraço!
