relaying error message when mail sent via Iphone or samsung galaxy

[ben1967]

Dear All,

This is not a zimbra related issue but will really appreciate if someone out there would help me out.

I am running ZCS 7.1.1 and everything us working fine

now lots of users have I-phones or android based samsung phones and i am having a relaying denied issue

let me explain.

I set up the iPhone as a imap client but when I send mail it says relaying denied
but I am able to receive mail perfectly
this happens only if the iphone is connected to the phone company via 3G

but if the iphone is connected through my companys wifi it works fine .. I am able to send and receive mail

Is there any settings in the iphone I need to specify.


Once again apprecite your kind reply

regards

Connect to port 587 (the correct Submission port) and authenticate (also use SSL) and you'll be able to send mail using your Zimbra server.

Thanks a lot phoenix really apprecite your quick reply i will test it and let you know

[ben1967]

actually I was disabling TLS and checking it..
the I phone used to complain if you want to continue without SSL and I used to say yes
will try your suggestion

Dear Phoenix and guys,
I did try once again setting the iphone 4 to send and receive mail through my zimbra server

the way I did was settings ==> mail ==> other account ==> choose Imap.

entered the settings as follows

name:
email address:
description:

incoming server:

host name :gave ipaddress
username: abc123
password:****

outgoing server:

host name: gave ipaddress

username
passwd optional

use ssl yes/no

authentication-- options are password , NTLM , http md5/digest md5 chalenge response

server port tried using 587..
is there anything I am missing
apprecite your kind help

below is the /var/log/maillog

dear Guys the problem is solved.
actually wht phoenix said was right regarding the port
actually in the outgoin server I was not putting the username and password and also SSL needs to be check.
did u mean SSL when you said TLS since there is no option for TLS

so all 4 things has to be there and correct that is the port, username and password and ssl on
else it will not work

Thanks once again phoenix

Yes, I did mean SSL (I'll modify most post above for future visitor to this thread).
