RoundCube "Compact" Option no email working

[kextra1]

Hello,

I recently clicked the "Compact" button on the Roundcube ISPConfig .pkg to compact my inbox mail and now I can send but cannot receive mail.

No mail is received using this email address. All other email addresses are fine.

Any help?

What does the "compact" button in roundcube webmail attempt to do?

Thanks for ANY help on this whatsoever. I am completely baffled. This is my financial email account and I'm really messed up without it.
