Hello all - I've been able to modify my postfix configuration so I can send email out on port 587, but when I tried to send an email to myself from Gmail or from work, I don't receive any emails. Does someone have any idea why this is happening and perhaps a way to see why incoming emails are being blocked ? Thanks ! Mike
The MX and A records still point to my mail server, as they have for the past 10 years. If I'm relaying through Gmail, I don't need to them, do I ? I also called my ISP and they said: - they are blocking port 25 both inbound and outbound - If I set up SSL, inbound is port 995 and outbound is 465 - If no SSL, inbound is port 110 and outbound is 587 I'm guessing by "SSL" he meant "TLS". Here is a snippet of my master.cf: # Postfix master process configuration file. For details on the format # of the file, see the master(5) manual page (command: "man 5 master"). # # Do not forget to execute "postfix reload" after editing this file. # # ========================================================================== # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (100) # ========================================================================== smtp inet n - - - - smtpd 587 inet n - - - - smtpd #submission inet n - - - - smtpd # -o smtpd_tls_security_level=encrypt # -o smtpd_sasl_auth_enable=yes # -o smtpd_client_restrictions=permit_sasl_authenticated,reject # -o milter_macro_daemon_name=ORIGINATING #smtps inet n - - - - smtpd # -o smtpd_tls_wrappermode=yes # -o smtpd_sasl_auth_enable=yes # -o smtpd_client_restrictions=permit_sasl_authenticated,reject # -o milter_macro_daemon_name=ORIGINATING
that is your problem , outside mail servers will always try to comunicate with your MX on port 25 , if you ISP is blocking it then you wont get any mail ask them if they provide a smart host that you can use for relaying mail
