postfix problem second wordpress

I am sory for my bad english, this my problem, with postfix in linux

I work in a single vps, with two wordpress, ” contact form send mail just for mail “[email protected]”,
[email protected] [email protected]:passwd-2
[email protected] [email protected]:passwd-1
[smtp.zoho.com]:587 [email protected]:passwd-1 <<<<<<

if I change file sasl_passwd like this contact form send mail just for “[email protected]”,:
[email protected] [email protected]:passwd-2
[email protected] [email protected]:passwd-1
[smtp.zoho.com]:587 [email protected]:passwd-2 <<<<<<

if I use shell to send mail like this, both cases work perfectly :
echo “this is the mail2” | sendmail -F “Bogus User” -f [email protected] [email protected]
echo “this is the mail2” | sendmail -F “Bogus User” -f [email protected] [email protected]

so I need find problem with config wordpress or config postfix ?
if there solution how send message from both wordpress, please help,
