Error after sending an email

[SIZE=14px] Hello, inside the event OnAfterInsert, I’m sending an Email without attachment. Data saves correctly and mail is sending ok, but I got this error :

is_writable(): open_basedir restriction in effect. File(/var/tmp/) is not within the allowed path(s): (.:/web/vhosts/mar278/www:/web/vhosts/mar278/privado:/web/tmp)

In development enviroment is working fine but in production not. The configuration tmp is this:

I dont have access to PHP.ini in the server to modify open_basedir

Can you help me. Regards. Guillermo.
