HELP: Cannot send mail when off network??

Hi we have set up the mail server on our Leopard server to host mail for our domain, we can successfully recieve and send mail when clients on on our internal network, and when off network can send as well. But when a client is not on the internal network (e.g. StarBucks or at home), they can not send mail using our server, even when on VPN. We have selected to use authentication, and the connection doctor in mail shows it is able to log in and connect with the server. any ideas?

I see it's been a month with no on-line response to your problem from Apple or anybody. That may indicate there isn't one that works 100%. I am having the exact same problem with all of the same companies. Add to it that I cannot get e-mail on my PC at home/office when the I-phone is turned on. I too have been in contact numerous times with Charter and Verizon, and have received zero return phone calls from either when promised. It seems that many people have these problems, but so far nobody can fix them? And I paid for this phone? I never thought I'd be at a point where I would consider returning to my Blackberry.

Cannot send mail when out and about

Hey all
I recently got my Iphone4 and synced it to my mail on my computer. When using my iphone at home it send mail without a problems as it goes through my wifi I have. Internet is virgin media and mail is with windows mail by the way incase its important.
When I am out and about I can recieve email without a problem but cannot send anything at all.
What do I need to do so that I can send mail no matter where I am?
Thanks

It's most likely exactly the same issue. Most ISPs only allow you to use their outgoing email server whilst connected to their internet service.
With a mobile device like an iPhone you won't always be connected to your ISPs internet service. Sometimes it will be your mobile network provider (when on 3G), or on some other WiFi service like a public hotspot in Starbucks or McDonalds.
When you are not connected to your ISPs internet service, you either have to use the SMTP server of the internet provider you are connected to (awkward to keep changing, even if you know it), or you "authenticate" your connection to your ISPs SMTP server (if they allow it) with a username and password so that they can verify it is you who is using their server and not some spammer.
The best way to avoid all this, is to use an email provider that is totally independent of any internet provider and will therefore work from anywhere, regardless of how you are connecting to the internet.
GMail and Apple's own MobileMe offer authenticated SMTP servers that work from anywhere.

Cannot send Mail when in different country

Hello all
I have setup an SLS as Mail Server. I can send and receive mail OK (no SSL). I had complaints that when clients travel to different countries they cannot send e-mails, even if we have set SMTP with authentication. Is there any way to avoid this? Our static IP responds to the name of the mail server (mail.serveradmin.gr)
host mail.serveradmin.gr
+mail.serveradmin.gr has address 85.72.48.65+
BUT IP itself no:
+host 85.72.48.65+
+65.48.72.85.in-addr.arpa domain name pointer XXXX.static.otenet.gr.+
This is because Greek ISP does not point one static IP to the name of your choice, you have to buy a block of 16 (which is expensive).
In Exchange 2007, you can set the so-called Internet Host Name of the System, and there put the real authoritative answer (XXXX.static.otenet.gr)
Is there anything similar in Dovecot?
Thanks
Kostas

Here is the postconf output:
As I mentioned before, Greek ISPs does not give you reverse DNS if you have one static IP, only if you buy a 16 block, which costs 50 euros per month.

Hi,
I had the same issue on my iPhone 5S. My internet/email provider told me to uncheck (turn off) USE SSL under Mail settings, and it worked perfectly for me.

lots of people seem to be havgin a problem sending email from iCloud webmail.
does your email address have uppercase characters in it?
if so, try creating an alias in lowercase (go to preferences in iCloud webmail and select 'accounts') and see if email sends okay from that

IPhone4 when replying or forwarding mail messages i get a message that says Cannot Send Mail address rejected by the server because it does not allow relaying

When forwarding mail this is what i get
Cannot Send Mail
A copy has been placed in your Outbox. The recipent _________________(email address) was rejected by the server because it does not allow relaying.
Never had this problem before so not sure whats going on. Appreciate any help out there.

Sounds like there is something wrong with your SMTP server. Try going into Settings>Mail, Contacts, Calendars>select the email account in question, go to the Outgoing server (SMTP) and check the settings. It may be you do not have a username and password in one of the areas. The phone may say optional in a couple, but it is usually mandatory. You can also try a reset on the device, hold the sleep/wake and home buttons together until you see the Apple logo and then release. If neither of these work, then you will need to delete the account, then delete the SMTP server, then add the account back, ensuring you use your username and password everywhere, even when it says optional.

Get the correct mail server settings from your IT department.

What is the email provider? If it is from your home Internet service provider, they usually block sending when not on their network. If this is the case, see if you can log into the smtp server with username and password. If they allow that, you can enter that in the email account settings.

Hello lclaunch22
You may need to validate the account with Hotmail. When logged in to the Hotmail account on a computer, there are instructions on how to do this.

All of a sudden I cannot send mail but I still receive it. Help?

All of a sudden I cannot send mail although I still receive. Anyone have an answer to this?

Do you get an error message?
You can go back into the mail account settings and scroll to the outgoing mail server and see if you can enter a password, same one as your incoming mail server.

Mail can't send mail on home network

I am trying to help a friend who wants to move from Entourage to Mail. He has a MacBook Pro with 10.6.4 installed and his company uses Exchange 2003. He is moving to Mail due to serious calendar and contact syncing issues through Entourage and his iPhone/iCal/Address Book.
I have setup his Mail account to use IMAP with the Exchange Server. He can receive mail this way, but he cannot send it. Actually he can only send mail when he is at work on his company's network. I have turned off SSL and authentication is through Username and Password.
Funny thing is that Entourage can send and receive mail anywhere he has a connection, but Mail cannot. His company's IT department says that the settings I have in place should work.
How can I further troubleshoot this problem? Is it a server problem? I know 10.6's Mail doesn't support Exchange 2003, but I am not looking for full integration of exchange services.

You may be SOL as you need an SMTP server to send mail and the IT folks may not have it set up. You need a proper SMTP relay to send the mail, period. It doesn't matter what it's called, though convention usually has it set to smtp.example.com. mail.example.com would more often be the address for IMAP or POP connections.
Regarding the inability to send mail from an external network, this is the same problem: You still need an SMTP server to send emails. It's just that the SMTP server on the external network is likely different than the corporate SMTP server. What external network is it, and what is the SMTP server they have set up for machines within their network? Note that many networks don't enable outbound SMTP for random clients due to SPAM reasons.
