Hello all; As with most large ISP's, my ISP filters port 25 (SMTP). As a web hosting provider, I felt that my customers should be able to use my email server to send email, as well as receive it. It's kind of a value added feature So, here's how I did it: Open /etc/postfix/master.cf and add the following line: Code: 587 inet n - n - - smtpd This is for postfix only. Restart postfix and your done. This doesn't really have anything to do with ISPConfig, however maybe it should be an option...? EDIT: I forgot to tell you, SMTP will listen on ports 25 and 587
This is a great solution but when i try to send an email using 587 port, no auth is required and the server become an open relay. Any idea?
Yes, i tried to send a email from my network. Running telnet localhost 587 this is the output: debian:/etc/postfix# telnet localhost 587 Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. 220 debian.domain.tld ESMTP Postfix (Debian/GNU) ehlo localhost 250-debian.domain.tld 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH LOGIN PLAIN 250-AUTH=LOGIN PLAIN 250 8BITMIME quit 221 Bye Connection closed by foreign host.
I tried to use this tip from a remote pc with an outside ip but it doesn't work. When I send an email, i can't authenticate me using port 587.
Looks fine. What's the exact error message? What's in the mail log? Did you enable "Server requires authentication." in your email client?
Looking mail.log, when i use port 587, i have this error: Aug 3 16:14:58 debian postfix/smtpd[3759]: connect from unknown[192.168.0.4] Aug 3 16:14:58 debian postfix/smtpd[3759]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory Aug 3 16:14:58 debian postfix/smtpd[3759]: warning: unknown[192.168.0.4]: SASL LOGIN authentication failed Aug 3 16:14:58 debian postfix/smtpd[3759]: lost connection after AUTH from unknown[192.168.0.4] Aug 3 16:14:58 debian postfix/smtpd[3759]: disconnect from unknown[192.168.0.4] Thanks Falko
Is saslauthd running? What's the output of Code: ps aux|grep saslauthd ? What's in /etc/postfix/master.cf?

Using 25 it's all ok.
Change this line: Code: 587 inet n - n - - smtpd to Code: 587 inet n - - - - smtpd in /etc/postfix/master.cf and restart Postfix.
Great! Now it's perfect and i can send email using m isp-config server also if another isp block port 25. Thanks
Having the same problem I'm having the same problem and getting the same error message, but the fix does not work for me. Any ideas?
It's working This is what worked for me. I had to make both lines match: smtp inet n - n - - smtpd 587 inet n - n - - smtpd (I actually used a different port number than 587) One more thing for Evolution users: If you change the default smtp port, add the port to the end of your mail server like this: mail.yourserver.com:587
thanks to you guys i have the company email working.. as they are so tight on security. i cant use port 25 properly over the vpn so i now have 587 doing the same job. Keep up the good work guys. ---------------------------------------------------- i bookmark pages incase i become thick one day!!
TLS working but not SSL on port 587 As I stated earlier, these settings worked for me: smtp inet n - n - - smtpd 587 inet n - n - - smtpd TLS encryption works on the new port 587. It also works without encryption on this port. SSL encryption works on port 25. However, when I try to send an email to my server with SSL on port 587, it just sits in the outbox. Any ideas on what I need to change to make this work? I appreciate your help and thanks again for ISPconfig! Gary
Thanks for your quick reply. I am actually using port 2525 instead of 587. Here is what you requested: What's in /etc/postfix/master.cf: From mail log:
Hi All, it worked for me perfectly, however i want to use my ispconfig server as alternative smtp server for domains that are not hosted on the ispconfig server. I add the domain and create the desired users that should be able to use the ispconfig alternative smtp server, everything works perfect, only 1 thing do not - sending mails from that domain to itself. The ispconfig handles these mails internal. I have set "External Mailserver" for that domain but that didnt helped at all. I also deleted the domain from /etc/postfix/local-host-names but after running /root/ispconfig/php/bin/php /root/ispconfig/scripts/writeconf.php this domain is automaticaly added in /etc/postfix/local-host-names. What can i do to achieve my target? N/B I hope there will be an "ISPconfig way" doing this because i want ppl that do nnot have access to the server but only to ispconfig admin interface to be able to add domains and users which will be able to use the alternative SMTP port... Thanks in advance!!!!!
Did you do this only for the main FQDN (e.g. www.example.com), or also for the Co-Domains? Each Co-Domain has its own Options tab where you can select "External Mailserver".
