we are receving reports from several clients that they are having trouble sending emails, although they are receiving mail ok.
it appears that the mail client's smtp settings have changed back to the default port of 25. for our servers this port should be 587.
if you are experiencing this issue, please check this setting.
we know microsoft are slowly rolling out a large windows update which might cause this, although at this time we can't confirm that is the cause for windows based machines.
we are unaware of any recent updates to iphoones or Macs, but this same settings change has been confirmed by a customer using an iphone. .
