Hello,
I moved to a new server with integrated merak mail. since I forgot merak(used before), i missed to configure security options.
So before I realize the issue, my smtp server was used by spammers for 2 days, hundreds times
I configured security settings as what it should be (at least i hope)
then i realize, i can't send e-mail to gmail or hotmail.
gmail says "550 5.7.1 see our Bulk Email Senders Guidelines" yes, I saw its guidelines.
first, I creat SPF records via msn senderID wizard. it completed very well. then as gmail says, I created DKIM dns records. (in Merak mail, there is option to create DKIM, i created it and save it to DNS as TXT record)
it's been 2 days after doing the fixes above. but still i can't send mail gmail or hotmail.
(P.S, some of my domain in merak is forwarded to my gmail account i mean when a mail arrives to [email protected] it will forward to my gmail. and the surprise it, merak mail can forward them very vell :S but can't still send mail from outlook etc.)
