If you frequently sign in to your account on different devices through different browsers, your account activity may be considered suspicious and the service provider will disable your account.

Apr 10, 2017 · Ampli-fier commented on May 4, 2018. There was a problem with Delta Chat for Android, that ‘AUTH LOGIN‘ was not available from the client side (from Delta Chat). The server offered this mechanism, but the client did not find a match (for this mech) and sent ‘QUIT’. This is fixed with PR #295 and available in the next release.

The AUTH Command The AUTH command is an ESMTP command (SMTP service extension) that is used to authenticate the client to the server. The AUTH command sends the clients username and password to the e-mail server. AUTH can be combined with some other keywords as PLAIN, LOGIN, CRAM-MD5 and DIGEST-MD5 (e.g. AUTH LOGIN) to choose an authentication mechanism.
It monitors SMTP port on your server and detects failed login attempts. If the number of failed login attempts from a single IP address reaches a set limit (three by default), the attacker’s IP address will be blocked. Download RdpGuard to stop Brute-Force Attacks on your SMTP Server!
