Q: how to fix smpt error (435) and exim config error I have problem to use my server mail service with this error:

```2020-08-08 12:27:28 login authenticator failed for (User) [45.143.223.125]: 435 Unable to authenticate at present (set_id=helpdesk@compoteam.net): Undefined subroutine &main::smtpauth called.

2020-08-08 12:27:37 login authenticator failed for (User) [212.70.149.3]: 435 Unable to authenticate at present (set_id=michel@compoteam.net): Undefined subroutine &main::smtpauth called.

I have to note this, We gave wrong domain to our host provider to config and (set_id=michel@compoteam.net) is not in a correct form of our email actually  @compoteam.net is not correct it should be @compexteam.ir.
Because of this i think exim did not config correctly.
how can i fix this.
Im using direct admin.
Thanks.

A: Have you got the newest exim.pl file? try to update exim.pl and check your sending limits in /etc/virtual/limit (or limit_login)
Also check if /etc/virtual/compoteam.net/passwd exists for virtual mailboxes
