Hi, i installed a new server ubuntu server 9.10 with lamp, etc. after which i followed the following tutorial to setup Postfix, DoveCot, Squirell http://www.debianadmin.com/debian-mail-server-setup-with-postfix-dovecot-sasl-squirrel-mail.html It was working fine till here. After which i installed the spamassain which also got configured perfectly. I can send only 1 or 2 mails after which i get error here is my confid file of postfix The config of my host file. -------------------------------------------- I get the following error when i try to send emails. The mail system <[email protected]>: host mail.mydomain.com[70.38.xx.xx] said: 550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1) (in reply to MAIL FROM command) or if i play with the config <[email protected]>: mail.mydomain.com[70.38.xx.xx] said: 550-(mydomain.com) [210.211.xxx.xxx] is currently not permitted to relay 550-through this server. Perhaps you have not logged into the pop/imap server 550-in the last 30 minutes or do not have SMTP Authentication turned on in your 550 email client. (in reply to RCPT TO command) Fully frustrated with this, anyhelp or a link for this problem will be helpfull.
problem solved okie here is the small line that you need to addup to fix this problem smtp_helo_name = host.example.com in case you come up with any such error
