Hi Everybody, I'm having an issue with qmail and my server to send mails to some domains. Here is the error. This have been happening for three weeks.
qmail says: Sorry, I wasn't able to establish an SMTP connection. (#4.4.1) I'm not going to try again; this message has been in the queue too long. If I send the e-mail with any other server (even Windows or Linux) it goes through normally. I've perform all these tests, and they're all right: - Resolve MX of the domains. - Traceroutes to the servers - Pings to the servers - Nmap found all the ports that must be open, particularly the 25. - I've talked to the network administrators of the domains that I can't reach and they've told me that there is no block for my IP address (firewalls, blacklists, etc.) The only BIG PROBLEM is that I cannot make "telnet (mailserver) 25". It ends in a time out after a minute. I've also talked with my ISP, and It's not a routing problem. If it was a routing problem, I couldn't reach the domains with any other servers of my subnet... (that already happened to me). These are some of the mail servers that I can't reach with my Debian: mail.matrocolayasoc.com.ar, mail.skytel.com.ar, mail.ecogas.com.ar, and others... I'm running a Linux version 2.4.20-pre8 (gcc version 2.95.4 20011002 (Debian prerelease)) I appreciate any comment.
