I've installed exim+dovecot on my CentOS7 VPS and setted it up according to a few articles from the web. Created mail accounts admin@website.com and no-reply@website.com via VESTA CP. Then I installed RoundCubeMail and tried to send an email, but failed. If I'm trying to send an email from no-reply@website.com exim main.log says:
H=(website.com) [IP] sender verify fail for <no-reply@website.com>: Unknown userH=(website.com) [IP] X=TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256 CV=no F=<no-reply@website.com> A=dovecot_login:no-reply@website.com rejected RCPT <myfriend@gmail.com>: Sender verify failedbut, if I'm trying to send email from admin@website.com exim main.log says:

MX record is mail.website.comhost in the exim config is mail.website.com
What is wrong here?Is this "admin@website.com"@mail.website.com entry in exim log is normal? Looks very strange.I noticed, that if mail account contains dots or dashes (no-reply@website.com, j.brown@website.com) it displays different error then if account with just 1 solid word (admin@website.com), why is it so?
If I need to provide some more information please ask.
