not enough info provided.
What mail application are you using?
The SMTP server, is it an OS X Server, your ISP, Google, etc?
Is the outgoing server on your LAN ?
What SMTP port are you using?

My problem is similar. Using Mac OS Mail. Every so often (random, no pattern) out of the blue the SMTP server (mediacombb) is forgotten. I don't have multiple outgoing servers, so it just asks me 'which one' I want to use. And of course there's only one listed, so I use that, and it sends just fine. WHY does it keep forgetting to use the one server I have listed? Makes no sense.

also- in your smtp settings in your client app, try changing the port from Auto to 587
this might not work at all, or it may solve the problem.. (hard to say becaue I don't have enough info about your config)
