problem now is that my isp has TOO many mta servers (10 so far that i
know of) and when i put all those 10 mta's in my SPF, it exceeds 512
character limit. should i just disregard spf altogether since my
e-mail gets rejected anyway? are there any other mechanisms like spf
that i can use? what should i do?
Quoting Erik Espinoza <[EMAIL PROTECTED]>:
Nope

i don't think they do.
Received-SPF: none (myserver.mydomain.com: domain at optonline.net
does not designate permitted sender hosts)
so i guess there is nothing i can do?
