My e-mail program is INCREDIMAIL (Portuguese version) and I hsve some accounts correctly configured there. The problem is: after some time, when the program tries to connect and send/receive messages, an error message appears indicating a problem and suggesting to check servers´configurations. So doing, I saw that servers´names have been changed without any personal action, generally including a <#> character and another ones. If then I change to the appropriate servers´names, the e-mail program comes back to normal operation.
What kind of error is this and how can I fix it?
