550 error when emailing

P: n/a
Don't know if this is new news, old news or no news. Every time I tried to
email with my php/mysql combo I would receive a email back from the system
administrator with about 5 of the addresses listed with a message like this:

550 not local host <hostname>, not a gateway

Tried all the php fixes, ISP technical support, checked for port 25 blocking
and domain host support no dice. These were/are all good host names. Turned
out that in typing in and/or importing addresses some (Those being rejected)
were typed in capitol letters. As soon as they were converted to all
lowercase the problem went away. I posted this because you have saved my a**
so many times I can't count them. Why it worked I do not know but it worked.

God Bless you,
Al Kolff
