When their servers are experiencing an "outage" , I see: Oct 28 09:04:46 mta1 postfix/smtp[18570]: connect to wec-imail3.bank.com[xxx.xxx.91.93]: Connection refused (port 25) Oct 28 09:04:46 mta1 postfix/smtp[18570]: connect to wec-imail2.bank.com[xxx.xxx.91.92]: Connection refused (port 25) Oct 28 09:04:46 mta1 postfix/smtp[18570]: connect to wec-imail4.bank.com[xxx.xxx.91.94]: Connection refused (port 25) Oct 28 09:04:46 mta1 postfix/smtp[18570]: connect to sls-imail2.bank.com[xxx.xxx.184.92]: Connection refused (port 25) Oct 28 09:08:14 mta1 postfix/smtp[4818]: connect to wec-imail1.bank.com[xxx.xxx.91.91]: Connection refused (port 25) Oct 28 09:08:14 mta1 postfix/smtp[4818]: connect to sls-imail2.bank.com[xxx.xxx.184.92]: Connection refused (port 25) Oct 28 09:08:14 mta1 postfix/smtp[4818]: connect to sls-imail4.bank.com[xxx.xxx.184.94]: Connection refused (port 25) Oct 28 09:08:14 mta1 postfix/smtp[4818]: connect to sls-imail3.bank.com[xxx.xxx.184.93]: Connection refused (port 25) Oct 28 09:12:42 mta1 postfix/smtp[12046]: connect to wec-imail4.bank.com[xxx.xxx.91.94]: Connection refused (port 25) Oct 28 09:24:35 mta1 postfix/smtp[24419]: connect to sls-imail3.bank.com[xxx.xxx.184.93]: Connection refused (port 25) Oct 28 09:24:35 mta1 postfix/smtp[24419]: connect to wec-imail4.bank.com[xxx.xxx.91.94]: Connection refused (port 25) Oct 28 09:24:41 mta1 postfix/smtp[24419]: connect to wec-imail1.bank.com[xxx.xxx.91.91]: Connection refused (port 25) Oct 28 09:24:41 mta1 postfix/smtp[24419]: connect to wec-imail3.bank.com[xxx.xxx.91.93]: Connection refused (port 25) Oct 28 09:24:41 mta1 postfix/smtp[24419]: connect to sls-imail2.bank.com[xxx.xxx.184.92]: Connection refused (port 25) Oct 28 09:28:31 mta1 postfix/smtp[22520]: connect to wec-imail2.bank.com[xxx.xxx.91.92]: Connection refused (port 25) Oct 28 09:28:31 mta1 postfix/smtp[22520]: connect to sls-imail3.bank.com[xxx.xxx.184.93]: Connection refused (port 25) Oct 28 09:29:22 mta1 postfix/smtp[6856]: connect to sls-imail5.bank.com[xxx.xxx.184.95]: Connection refused (port 25)
At these times, I'm also unable to telnet:25 into their mail servers (I've tested on several ISPs and outside my firewall to make sure it wasn't something with my Internet connection). I managed to get a hold of their tech people, they admitted that it was due to SPAM, and they sent out a company-wide email warning their clients about it. As I said, I'm pretty confident that the problem is on their end. -Scott -----Original Message----- From: Terry Carmen [mailto:[EMAIL PROTECTED] Sent: Friday, October 31, 2008 7:04 PM To: Vintinner, M.
