Android 8.1.0. Unable to connect to smtp with any clients

5871127 shared this problem 2 years ago

Dear Support,

I am unable to connect to the smtp with any Android clients (K-9, FairEmail, Simple Email) all the clients reject the connection because:

  1. 535 5.7.8 Error: authentication failed: UGFzc3dvcmQ6

Change the port from 465 to 587 does not solve the issue.

Since the moment three clients out of three have the same problem I guess the issue is on your side.

Please advice!

I just realized that neither the Webmail is working, what's wrong with the SMTP, it is quite annoying buying a service that doesn't work...

  1. Wrong or missing login data to access mail transport server smtp.mailbox.org. Please check associated account's settings/credentials.

I can't find where check the smtp server in the webmail, please there is anybody out there?
