Imap problem when sent a message

Hi, I have a problem with IMAP configuration, when I send a message, it’s result duplicate in sent folder and an error message popup appear with code: unknown __255.


I keep getting asked for my password while waiting for my e mails to come in. in dropdown box the password is already correct so is my E mail address. sometimes i deleat  the password & re type it that works for a while till next time. but sometimes the dropdown box appears while reading my e mails. Hmmm

In my case another email client works fine, thunderbird for example. The password it’s correct and not asked again while mail to come in.

Hello Gabriel,
could you copy the content of Tools>Operations>Log window next time this error comes up?
