Hi guys,

today chkservd started reporting that exim is down, when it's not. Here's the log ;
Code:
TCP Transaction Log:
<< 220-cpanel.domain.com ESMTP Exim 4.91 #1 Wed, 17 Apr 2019 10:25:16 +0200
<< 220-We do not authorize the use of this system to transport unsolicited,
<< 220 and/or bulk e-mail.
>> EHLO localhost
<< 250-cpanel.domain.com Hello localhost [127.0.0.1]
<< 250-SIZE 52428800

<< 250-PIPELINING
<< 250-STARTTLS
<< 250 HELP

somerandomstringhere
<< 503 AUTH command used when not advertised
exim: ** [503 AUTH command used when not advertised != 2]
: Died
I'm not sure what exactly happened, but SMTP via port 25 is not working. TLS on 587 is working fine.
The only option in exim I could think of to be related to this issue is ;
"Require clients to connect with SSL or issue the STARTTLS command before they are allowed to authenticate with the server. [?] ON " which is ON by default. I turned this off and on last night in order to test something, but it's left at where it was.
Also " Allow Plaintext Authentication (from remote clients) " is set to ON.

Can someone point me in the right direction here? Thanks.
