What? How does letting a home user send AUTH email via port 25 to there own
corporate email server interfere with SPF? The only reason I would think
ISP are blocking port 25 out from a residential line is to prohibit spammers
from sending out email.
Let say user [EMAIL PROTECTED] sends mail through his ISP's mail server smtp.myisp.com. If the receiver does an SPF check, it will look to see if the sending sever (smtp.myisp.com) is in the SPF record for acme.com. Probably it is not; and will cause an SPF FAIL, unless the mail admin for acme.com has included the outgoing smtp server(s) for myisp.com to the acme.com SPF record.
