View Full Version : [SOLVED] Problem with outgoing mail from server

26th August 2011, 14:42
Hello, I'm from Argentine and my english is a little poor. I have a debian server that I had setup with the perfect server guide (lenny + Ispconfig 3 + BInd +Dovecot + postfix) http://www.howtoforge.com/perfect-server-debian-lenny-debian-5.0-with-bind-and-dovecot-ispconfig-3
But this is not a question about ISPconfig since everything is working ok. My problem is that my ISP blocks port 25 but for outgoing mail. I had modify my master.cf from my postfix 2.5.5 for use the submission port (587) and my clients can connect to my server via smtp but the mails are getting queued in my server because it still sending the mails through the port 25. Is there any way to change the outgoing port for sending mail ??

Sorry If my english is not the best, thanks in advance guys

I suggest you try to set up Postfix relaying: http://www.howtoforge.com/postfix_relaying_through_another_mailserver

Hi falko, first of all thanks very much for your help. I follow that guide (http://www.howtoforge.com/postfix_relaying_through_another_mailserver) and I still can't send mail from my server.
The log for the error is:
(SASL authentication failed; cannot authenticate to server smtp.ejemplo.com[xxx.xxx.xxx.xxx]: no mechanism available)

I have found a guide that says: "you have probably forgotten the smtp_sasl_security_options line in /etc/postfix/main.cf." but (https://help.ubuntu.com/community/GmailPostfixFetchmail)

That line is in my main.cf after follow the guide for relaying, at the end of my main.cf I have:

smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =

Any Idea??

Thanks in advance

Can you send mails through smtp.ejemplo.com with a normal email client like Thunderbird or Outlook? If not, your login details are probably wrong.

yes, actually is configured in a mail client and I can send mails without problems

The log for the error is:
(SASL authentication failed; cannot authenticate to server smtp.ejemplo.com[xxx.xxx.xxx.xxx]: no mechanism available)
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =

Try changing following line in main.cf
smtp_sasl_security_options = noanonymous

Hope this works.

smtp_always_send_ehlo = yes

at the end of the file but still te same error:

any idea??

Hi again, in my mail.warn log file I have "server01 postfix/smtp[11312]: warning: SASL authentication failure: No worthy mechs found".... after a google search I found that the reason for this error could be that I don't have the cyrus-sasl packages. Could be?? In that case, what packages should I have to install in debian lenny? I have installed libsasl2-modules but still the same error. Any ideas??

Thanks in advance

19th September 2011, 17:46
Hi again... seems that the libsasl2-modules did the job; I forgot to restart postfix after install that package. When I reload it the mails go outside throw the smtp of mi ISP.:):)

Thanks a lot for the help
