Hellow everyone! I had a mail problem where I couldn't send mail outside my server, and attempted to change the port from the default of 25 to 587. (My ISP blocks port 25 on outgoing connections) I attempted numerous ways, but failed to do so and I had to keep going back to the backups to restore my server for web operation and incoming mail. I still had the same issue for 3 weeks, so I just started over and rebuilt it again with the "Perfect Server Debian Lenny w/ ISPC 3". I followed everything as I did before, making minor adjustments that were suggested. I thought this would resolve, but I still have the same issue. When I create a new mail account using ISP Config 3, and get the confirmation email sent from ISP Config 3, it marks it as ***SPAM*** Welcome to your new email account." Why is the server still hating itself in terms of spam? Is there a way to change the SMTP port from 25 -> 587 so I can send mail again? Tell me what info you need and I'll post it. Thanks for the help everyone!

Was this something new this year? When I set my first server up months ago, this step wasn't needed, unless I missed something? The DNS records I had to set where only in GoDaddy (where my domain name was registered) like the MX Record etc... So I would setup the DNS record in the ISP Config Control Panel instead of GoDaddy? I only have one IP address, so I thought I couldn't host my own DNS (unless you have two or more)
Please edit the spam rule(s) in ispconfig, so that tag level is empty and tag2 level is set to ***SPAM***.
@Till: I have set that so now my server does not say SPAM anymore. Wonderful Till, thank you! Is there anyway to change the port to send mail from 25 -> 587? I have to do this because my ISP is blocking port 25 and I can't send mail. @Falko: I have tried to add DNS records, but I still can't get that portion to recognize my server / mail server, where it did work before without adding these records. I use GoDaddy to host the DNS until I can get another server and another IP address to host my own DNS. Is there some way to do this with only one IP? If so, do tell! =) Thanks!

OK, I changed the port by doing what that link said. BUT, even though I uncommented that line, it seems as though POSTFIX is still trying to send on port 25! See below: Code: Jun 15 09:11:40 alphaserver1 postfix/smtp[24726]: connect to vztpa.verizon.com[192.76.82.162]:25: Connection timed out Jun 15 09:12:10 alphaserver1 postfix/smtp[24726]: connect to vzsac.verizon.com[192.76.84.38]:25: Connection timed out Jun 15 09:12:40 alphaserver1 postfix/smtp[24726]: connect to vzsac.verizon.com[192.76.84.39]:25: Connection timed out Jun 15 09:13:10 alphaserver1 postfix/smtp[24726]: connect to vzsac.verizon.com[192.76.84.40]:25: Connection timed out Jun 15 09:13:10 alphaserver1 postfix/smtp[24726]: 9107F10881C: to=, relay=none, delay=150, delays=0.01/0.01/150/0, dsn=4.4.1, status=deferred (connect to vzsac.verizon.com[192.76.84.40]:25: Connection timed out) Jun 15 09:14:52 alphaserver1 postfix/qmgr[24518]: B51FA10881A: from=, size=1252, nrcpt=1 (queue active) I still can't send mail! Is there a way to make POSTFIX use 587 all the time, instead of 25 as default? Yes, I have restarted POSTFIX after making the changes =)

Should I be uncommenting the option flags after submission or smtps to enable port 587 as the default smtp port or not? What am I missing?
Here is the delivery report for the emails that don't send out. I know they are timing out because they are still sending on port 25, so how do I disable port 25 for sending, and keep 587 as the default for sending! Code: Reporting-MTA: dns; alphaserver1.sufuku.net X-Postfix-Queue-ID: B51FA10881A X-Postfix-Sender: rfc822; [email protected] Arrival-Date: Tue, 15 Jun 2010 09:05:33 -0400 (EDT) Final-Recipient: rfc822; [email protected] Original-Recipient: rfc822;[email protected] Action: failed Status: 4.4.1 Diagnostic-Code: X-Postfix; connect to alt4.gmail-smtp-in.l.google.com[74.125.95.27]:25: Connection timed out See my previous post for other command outputs, am I missing something in my /etc/postfix/master.cf?
Last attempt at fixing this port 25 issue! I think I understand what is wrong! I know this: - My ISP started blocking port 25 recently, which stopped my emails from getting out. - My ISP said to start using port 587, because that is still open - I tried to change the port to 587, but someone told me that Server -> Server communication for mail can only exist on port 25, is this correct? If so, this is why I cannot send mail, and why it is still trying to send on port 25 as opposed to 587. Can anyone verify this, or is there a way to send mail to another mail server NOT on port 25?
Yes, thats correct. Port 587 is only for connections from client > server and not server > server. But most providers allow connections on port 25 to their own mailserver even if they block port 25 for connections to all other servers. You should ask your provider if thats the case too in their setup. Because then you could use the mailserver of your provider as relay for your mailserver.
