login_server:
driver = plaintext

/usr/sbin/pwauth"}{1}{0}}
server_set_id = $auth1
server_prompts = <| Username: | Password:
Looks like the user #xxxyyyy'uuss+zzz is authenticated, but for sure it doesn't
exist in my /etc/passwd, neither /etc/shadow
Did you try to pass that user to your script with random password?
Yep, and auth is refused.
Did you try to pass that server_condition expansion through exim -be with
that user?
Nop, I will
Anyway, passing user input to script is not safe, notice that login name
contains the aphostrophe char, which breaks your quotation, duno how
it is interpreted... Why you do not use pam{} expansion?
I'm in Docker, I'll investigate in that direction. Thanks.

Thank you Slavko.
As an immediate fix I added the following in my exim.conf
drop message = REJECTED - Sender Verify Failed - error code
\"$sender_verify_failure\"\n\n\
The return address you are using for this email message
<$sender_address>\
does not seem to be a working account.
log_message = REJECTED - Sender Verify Failed - error code
\"$sender_verify_failure\"
!hosts = +no_verify
!verify = sender/callout=2m,defer_ok
condition = ${if eq{recipient}{$sender_verify_failure}}
deny message = Restricted characters in sender address
domains = +local_domains
senders = ^[#] : ^[.] : ^.*[@%!/|#+]
deny message = Restricted characters in sender address
domains = !+local_domains
senders = ^[#] : ^[.] : ^.*[@%!/|#+]
Hopefully, that'll provide me with delay awaiting to fix the LOGIN issue.
thx and reg
