Can I config the ispconfig to use different relayhost when send email to different domain? e.g.: all email send from firstname.lastname@example.org to: email@example.com -> will use local trans to send. to: firstname.lastname@example.org -> relay to mail.isp1.com to send. to: email@example.com -> relay to mail.isp2.net to send. if no match, will use default setting to send. possible?
