[TYPO3-english] Plagin Mailformplus - mails not come

[Olga Zhuravleva]

I try to send mails from site throw plagin Mailformplus.
In plugin settings Mail From I set mymail at gmail.com

Mails to .. at gmail.com not come. In var/log/mail I see:
from=<nobody at kamsan-kovrov-linsrv.site>.
1.Why field from is not mymail at gmail.com?
2.May be mail server filter such (nobody at kamsan-kovrov-linsrv.site) e-mails?
