I have a webserver at a ISP somewhere. Probably in tele house london, which I rent out on one of these server packages.
I don't know much about linux at all,
What I noticed is that my /var partition was full on close looks it was the /var/spool/mqueue was fulll of files.
Question is what causes this and what are they, and how do I prevent it from happening in future.
I look on google and someone said run sendmail -q but what does that do.
Any help would be good.
