Any limitation for the number receipients that can be included from a single mail from peoplesoft ap

HI All,

I would like to check whether there is any limitation in peoplesoft for the number of receipients that we can add in a single mail ?

Any of you are aware about any such configuration in PIA or configuration files??

Though there is no particular limitation defined anywhere in peoplesoft,  Do any of  you find/think about any other challenge if we add about 15000 receipient in a single mail?? (May be a performance issue/stuck,  SMTP server level limitations, PS environment hang etc.)

Please help us with your expert thoughts/ideas.

Thanks,

George.
