[lug] question about webmail

[Paul E Condon]

My ISP allows me to set up email accounts on one of his servers and
to access them via the web using squirrelmail. I have set up such an
account for one of my daughters and checked it out and it works for
me, but not for her. I ask ISP support people and they suggest that
servers at her place of work have blocked port 2095 which they say
is used for web access to the email files. I wonder. Why is a special
port needed just to have web access to files on the server. I know
port 25 is used for SMTP, but to access your own email ...

I don't have any special knowledge of email protocols. Does what I
am being told make sense? If no, where can I read stuff that will
enable me to argue with them effectively?

TIA

PS port 2095 is listed as being assigned to 'NBX SER'. What is that?
