Report each day email error

[fenz050896]

Hello all, I use MetaTrader 4 Server Sendmail 4.00 Build 1170 (Dec 20 2018) and I also have vps for smtp used in that software.

previously, the smtp configuration that I created in the metatrader software if I tried configuring it in outlook or other email client software that configuration worked fine.

therefore, I cannot send mail reports.

As for the error from the log that I got is as follows:

2019.02.28 05:00: 16.002 Send: SMTP 'd-caps.com' ('s*****[e-mail]') is used for the group 'Sample'

2019.02.28 05: 00-1624 Send: connected to 'd-caps.com'

2019.02.28 05: 00: 16,362 Send: authorization for 'Sample' failed send data, server error code [220]]

2019.02.28 05:00: 16,367 Status: err 100000025 => s*****[e-mail] (not sent)

can anybody tell me what is happening here, and why ?
