hi
After the updating of CWP to 0.9.8.70 version, I have a problem in connecting by Outlook. It could be connected to POP3 but in the stage of send test mail, it gives the error (Send test email message: Outlook cannot connect to your outgoing (SMTP) email server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).)
Rather I have tested the port 25 firewall and that was open, but I could not connect by telnet, the error is about the connection time out.
Please give a guidnece, if possible.
best regards.
-
do your server really allowed mail through 25 ? if connection is closed through telnet probably port 25 is closed
-
Yes I am sure, I have tested this port from ping.eu and I got it is open.
config CSF inculudes:
# Allow incoming TCP ports
TCP_IN = "20,21,3031,25,53,80,110,143,443,465,587,993,995,2030,2031"

please rebuild the mail server and check it again.
-
Thanks for your response.
I did this but this problem exists in 3different servers simoltaneously. :(
-
can you post the error logs
-
tail -f /var/log/maillog includes only this errors:
Oct 26 14:40:21 srv1 postfix/smtpd[16415]: fatal: open database /etc/postfix/sender_whitelist.db: No such file or directory
Oct 26 14:40:22 srv1 postfix/master[16238]: warning: process /usr/libexec/postfix/smtpd pid 16415 exit status 1
Oct 26 14:40:22 srv1 postfix/master[16238]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling
Plz pay attention to the point that the Postfix is working correctly, because I have received forwarded root emails.
-
simply comment out this line in /etc/postfix/main.cf
check_client_access hash:/etc/postfix/sender_whitelist
or, create /etc/postfix/sender_whitelist file, and run postmap
touch /etc/postfix/sender_whitelist
postmap hash:/etc/postfix/sender_whitelist
Btw, when you telnet port 25 your server from ping.eu, that will only cek incoming port25.
to check outgoing, telnet other server from yours
-
After checking different sides, CWP had no problems, the ISP Port 25 had closed and I substitute Port 587 instead, eventually the problem was solved.
