If I understand you correctly:
a) you provide a mail service
b) Your customers want to send mail with the sender address
usergmail.com to MSN and Hotmail users.
c) they want to send that mail via your E-Mail Service
Your Problem might indeed be, that gmail has SPF records set and do not
list you as permitted sender.
Gmail has following SPF records:
% host -t TXT gmail.com
gmail.com descriptive text "v=spf1 redirect=_spf.google.com"
% host -t TXT _spf.google.com
_spf.google.com descriptive text "v=spf1 ip4:220.127.116.11/23 ip4:18.104.22.168/19 ip4:22.214.171.124/20 ip4:126.96.36.199/18 ip4:188.8.131.52/17 ip4:184.108.40.206/20 ?all"
Those IPs are marked as valid sender. ?all indicates, that other MTAs which send
mail as gmail.com shall pass because from
Result Explanation Intended Action
Normal The SPF record specifies explicitly that pass
nothing can be said about validity
However, nobody knows (as you didn't provide Failure Reasons produced by
MSN / Hotmail) what exact the cause is. It MAY be that MSN doesn't interpret
SPF records correctly.
Thus - provide logs, provide reject/bounce/DSN messages.
