Agreed. One can clearly see that the server responds to "AUTH LOGIN" in
the working case. And if it once did and later doesn't, it's a server
issue:

[15:37:35] ESMTP> AUTH LOGIN
[15:37:35] ESMTP< 334 VXNlcm5hbWU6
[15:37:35] ESMTP> [USERID]
[15:37:35] ESMTP< 334 UGFzc3dvcmQ6
[15:37:35] ESMTP> [PASSWORD]
[15:37:35] ESMTP< 235 Authentication succeeded

[15:45:59] ESMTP> AUTH LOGIN
[15:45:59] ESMTP< 500 unrecognized command

Also, what appears in the log with TLS enabled? Talking to the server
from the outside, it doesn't offer plain auth for a test:

$ telnet mercury.linksky126.com 25
