I can't send e-mails using Outlook to any client with an AOL address. First
the delivery is delayed & then 'the recipient could not be reached. Couldnot
deliver the message in the time limit specified.' This has only just started
happening.
Can anyone help?

Hi - when you post in here, please make sure you post your version & SP
level of Exchange, and as much detail as possible (including your Outlook/SP
version if this is a client issue).

That said -

AOL has started rejecting mail from a lot of servers in an effort to stop
spam. Some reasons for being blocked would be -

Your SMTP server has no reverse lookup records (PTR)
Your IP is considered to be on a dialup or dynamic IP [1]
Your IP or SMTP server has been blacklisted as an open relay

For the reverse lookup, check out your domain at www.dnsreport.com; ask your
ISP to create the record for you, presuming you have a static IP.
