    I am having problems connecting my phones email client in the HTC Desire outgoing SMTP mail client.

    It just wont connect, will with my mailbox though logs in fine when using that but fails for the outgoing, I am running an old centos distribution centos 4.8 and using ispconfig 2 like it said in the tutorials, the email servers acting fine can connect to it from work and at home just not by my phone, what could be the problem do you think?

    I mean I will list the details I have entered (missing out a few for security as usual):

    Username (setup when using this domain as a user on the shell commandline).

    Password (same as above, created and works fine for the incoming mail POP3)

    Security type: None (as I havent got it working either with any other so I thought it cant be that, could it?)

    Server port: 25 (port I use when I want to test it from work, sending emails out using that server, that works, so why doesnt my phone?)

    Can someone help? I'm clueless as to why this isnt working and its starting to really annoy me to no end, please any advice or help is greatly appreciated as usual.

    Kind regards and I look forward to any replies in advance:)

    I will try and set it up again and just double check.

    Last time I saw I couldnt even find any connection logs from my phone.

    I could search through the find the IP address of it at the time (as I think its always on the internet), but I will just doubly make sure.

    I wont need to add it to my hosts.allow list will I?

    Hmm see googlemail works fine, but this is really starting to bug me lol.

    Is there any good tutorials on setting up one outside of ispconfig admin interface?

    Like so I can set one up for myself?

    Just an idea incase I cant use this, just I tried squirrelmail on ispconfig but just couldnt work out how to set it up thats all.

    Thanks for your help so far,

    PS Here is a log of the activity just as an example:

    The first in the list above is the pop3 login my phone is allowing me to login to, jeremy is my username on that domain, I enter exactly the same details as per my public domain name, nothing seems to make it work.

    Its not actually coming up with any results for the smtp login though, doesnt seem to want to accept smtp logins, can someone help? (Jul 5 12:16:54 centos pop3-login: Login: jeremy [::ffff:] is my phones IP address, the rest is just an example of my outlook from work connecting to my server at home, works perfectly, really am stuck as to why this is not working, any suggestions?

    Ahh got it!!!

    Its amazing what a look on google does!

    Thank god for google, searched forums for various problems people where having with mobile phone networks, and they commonly block port 25, so instead of changing my other email clients from friends and stuff.

    I have opened ports 25-26, just to see if that works, wonderful it does!

    Going to attempt some kind of authentication in that aswell, just to make sure it works more securely aswell.

    Happy to know why though!

    Its not receiving any mail.

    Any suggestions?

    Like it doesnt appear in my inbox, any help is greatly appreciated have opened 25-26 on both my NAT firewall and my server but the actual service is the problem, is there anyway of allowing postfix to receive this?

    Thanks again.

    Does the MX record of your domain point to the correct server? You can check that by running
    dig mx

    Since it works anyway yes it does.

    The problem has nothing to do with my domain what so ever, its to do with the ports with postfix receiving a request to send out an email.

    On my mobile phone network they block the standard smtp port, all I want to do is change postfix config to a port, anything other than the standard port its configured to, basic really.
