Hi, today some mails are in our mailqueue. These mails cannot send out because of problems with destination Systems. first one is birce@bircetour.com.tr here ist sems they they have problems with thier DNS. Mails not arriving because the important so called mx dns record ist missing.  second one is ftunc@corendon-airlines.com and mgencturk@corendon-airlines.com here we only get 451 Temporary failure while processing your mail (in reply to end of DATA command)) from thier server. Regards Denny
