Strang attachment files under /tmp

[mikbull]

Hello,

I've been noticing files being created under /tmp/ with a naming convention of rcmAttmntXXXXXX  with the X's being random upper and lower case characters (see below)

-rw------- 1 apache apache  45727 Oct 21 09:33 rcmAttmnt2BePog

Does anyone know what these are?  Should I be removing them manually or are they auto removed by Roundcube?

Thanks
mike

they are temp files created by roundcube during the processing of attachments. yes roundcube cleans them up when its finished with them.
