SMTP timing out on some incoming mails
Posted on 2004-09-16
I have a client using MS SBS 2000 with exchange server - using DSL and a backup email server.
The problem is that most of the incoming mail is getting through but the rest is timing out. When this happens it is then queues on the backup email server nd when it tries to send again it also gets a time out.
I have switched on the SMTP log and the offending mails have a HELO,MAIL,RCPT,TIMEOUT,QUIT .
Exchange is not filtering any address - the firewall is not filtering any content or addresses.
Anyone any ideas
Thanks is Advance
