Hello,

I can receive and read mails. Everything works fine, but I can't save or send mails. In the WebMail log there is nothing but in the log files of my hoster I found these lines:
[client xx.xx.xx.xx] ModSecurity: [file "/etc/httpd/conf/modsecurity.d/rules/tortix/modsec/12_asl_adv_xss_rules.conf"] [line "37"] [id "341256"] [rev "18"] [msg "Atomicorp.com WAF Rules: Possible Cross Site Scripting attack (detectXSS)"] [data "842,ARGS:Parameters"] [severity "CRITICAL"] Access denied with code 403 (phase 2). detected XSS using libinjection. [hostname "xx"] [uri "/"] [unique_id "xxx"], referer: xx

Is this a know problem or is there anything I can do to solve this issue?

Thanks in advance
Manuel

We have never encountered anything like that. And from the log record, it's not clear which aspect of WebMail functionality triggers the error. We recommend checking ModSecurity support resources to determine that.

After your reply I checked if there is something I can do regarding ModSecurity. I figured out that I can disable some rules, so I disabled the XSS rule. I don't know if that is a good or risky thing but it works now.
Thanks for your help.
