Recently, I've been seeing a lot email being forwarded to my Imail = server that should have no reason going there, ie. email to hotmail.com, = yahoo.com, excite.com, etc. I'd like to prevent these connections from even being = made at all considering the heavy load the Imail server is already under:
Aug 24 20:21:38 mx1 postfix/smtp[42056]: 590932C1BD: to=3D<[EMAIL PROTECTED]>, relay=3Dmail.candidhosting.com[64.159.90.15], delay=3D73965, = status=3Dbounced (host mail.candidhosting.com[64.159.90.15] said: 550 not local host hotmail.com, not a gateway (in reply to RCPT TO command)) In main.cf, I have relayhost=3D[mail.candidhosting.com] and = permit_mx_backup set. =20 Could these be bounces that are being forwarded, or is this someone = trying to relay through my mail exchangers? Thanks. =20
