Email error - when using smtp

[anilp78]

Hi,

When am using smtp for sending email, i get the following error when i compose an email for a lead -

The first error that i get is -
Please check the current user mailid.It should be a valid mailid to send Emails

Then, when i add an email manually in the from field, i get the next error -
Warning: Creating default object from empty value in /home/iperac/xyz.com/corebos-master/modules/Webmails/Webmails.php on line 745

I was using sendmail earlier but the emails appear in spam, so i switched to smtp.
What could be the problem here? please help.

thanks,
