In my company, we use windows mail who ever has OS vista and Outlook Express 6 who ever has OS xp pro. from couple of days we are facing problems of outgoing mails from outlook - Our webhosting server is in california and we are able to send/receive mail thru our webmail (squirrel mail).
we are able to receive all mails but when sending mails the error is:
An unknown error has occurred. Subject 'test mail', Account: 'mail.world-med.com', Server: 'mail.world-med.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0B.
When I tryrom run command telnet world-med.com 25 I get 2 kind of replies
451 - The server has realised its limit for processing requests from your host - 451 Please try later.
220-ib bur.lunarbreeze.com ESMTP exim 4.69 #1 followed by date and time.
220 We do not authorise the use of this system to transport unsolicited, and/or bulk email
My Os is Xp pro service pack 3, Centrino Duo 1.66ghz, 1 gb ram.
thanks apreciate an early response.
As you have pointed out the mail server is the issue, I had to change the port settings of SMTP from 25 to 587, things are ok.
Appreciate for your quick response, I learnt a great deal about exim.
