Newsletter error

[belweder6664104]

Hi
When I try send newsletter, I've got this error:

Gateway Error

and was something about Apache :80 as I remember, Were sent only 300-400 emails via mandrill, the rest of 1000 are not

What can I change there??

i think its a timeout error.. you may need to increase execution time.... (maybe i am wrong but i think this is the cause)
