Testing the Mailmate application at the moment.

Given that I do not seem to have had issues with other mail clients I am inclined to think there is an incompatibility with  the MailMate app.  Had anyone else encountered  issues with this mail program?

Errors on importing imap folders  with the error being:
MailMate encountered the following error: “Failed to fetch data for 1 messages.”.
Mailbox: “INBOX/Chamber”.
This indicates a server bug. You can tell MailMate to always ignore messages involved in this type of error (for this account) or you can temporarily ignore the messages with the following UIDs: “113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159,160,161,162,163, ...”.
