New server, new IP address, same domain name? Could be that you're dealing with DNS transition delays. Check the TTLs on your domain records! -------- Original message --------From: "Fazzina, Angelo" <angelo.fazz...@uconn.edu> Date: 10/2/17 1:24 PM (GMT-07:00) To: njo...@megan.vbhcs.org, postfix-users@postfix.org Subject: RE: Trouble sending email to myself on new server i am building Hi, sorry if I posted in non-plain text format, did not know that was an issue. Will watch for it next time.
I have gone through 2 guys in security/networking department today and was able to finally prove it was firewall and not my postfix config being "wrong". I even turned off SELinux and iptables... Hopefully by Wednesday I can send email. Issue closed for now, thanks. -ANGELO FAZZINA UITS Service Manager: Spam and Virus Prevention Mass Mailing G Suite/Gmail ang...@uconn.edu University of Connecticut, UITS, SSG, Server Systems 860-486-9075 -----Original Message----- From: owner-postfix-us...@postfix.org [mailto:owner-postfix-us...@postfix.org] On Behalf Of Noel Jones Sent: Monday, October 2, 2017 3:54 PM To: postfix-users@postfix.org Subject: Re: Trouble sending email to myself on new server i am building [Please use plain text next time.
