[horde] Error connecting to smtp server

[XG41]

Hi,

After upgrading imp 6.1.4 I am unable to send email. I get this error message. I haven't changed anything other than to upgrade all upgradable packages. Using Ubuntu LTS.

I seem to recall someone mentioning a similar problem but can't seem to find the message. Has anyone else had this issue? Any help would be appreciated.

TIA
