webmail not showing up on one domain

[Trudurinn]

i have 4 domains hosted on my plesk server and they all work fine and the http://webmail.domain.com works fine on all of them exept one of them does not come up with webmail.domain4.com, only domain4.com and all works fine, mail is working and i can access the mail if i go to http://webmail.domain1.com and log in with [email protected] .
i have tried to remove domain4.com and create it again, but it´s the same all over again.

any ideas ?

I was also having this issue, turned out to be a rule in ModSecurity2.

Try:
tail -f /var/log/httpd/error_log

then try to open the webmail for the domain in a browser, if it fails due to mod sec you should be able to see an error like this:

[Thu Oct 18 09:32:56 2007] [error] [client xx.xxx.xxx.xxx] ModSecurity: Access denied with code 501 (phase 4). Match of "rx (?:\\\\b(??:i(?:nterplay|hdr|d3)|m(?vi|thd)|(?:ex|jf)if|f(?:lv|ws)|varg|cws)\\\\b|r(?:iff\\\\b|ar!B)|gif)|B(?:%pdf|\\\\.ra)\\\\b)" against "RESPONSE_BODY" required. [id "970903"] [msg "ASP/JSP source code leakage"] [severity "WARNING"] [hostname "webmail.doamin.net"] [uri "/imp/login.php"] [unique_id "dLnXKEEnx5MAAD6miwgAAAAH"]

This is a false positive and you can comment our the rule in:
modsecurity_crs_50_outbound.conf

The matter is that domain name webmail.domain4.com is not resolved, so it can not be accessed in the URL.

Just enable webmail for the domain through Plesk:

Domains -> domain4.com -> Mail -> Preferences -> WebMail [x]

When the option is enabled the appropriate DNS record from DNS template is added to the domain:

webmail.domain4.com. A <ip>

./anb

Exept, the "webmail" is checked. and allways was, i allready had looked for it.

Just found that webmail works, but only on the local net, not from tha wan side. How can that be ?

The only cause I see is that domain name webmail.domain.com is not resolved from outside, but is correctly resolved in your local network.
Check domain WHOIS for the authoritative nameservers and examine domain DNS zone on the nameservers.

Turns out that the problem was dns related.

it is fixed now,

Thanx all.
