Comment	>> ORDE: authentication[imp] Server denied authentication. [pid 25461 on >> line 1064 of "path/to/horde/imp/lib/Compose.php"] > > The issue is likely that your Horde SMTP configuration either has no > 'port' value or an 'empty' port value, so that you are connecting to > port 587 (which is the correct, preferred port but requires > authentication to be configured). Most likely before you were > connecting to port 25 (deprecated, doesn't require authentication). > > But if this is the case, this means that you didn't upgrade your > Horde config.
