nevorask –
Thanks for visiting our forums. I actually had a similar
situation. I had the iPhone 3GS and used it all the time on a FM transmitter in
my car. When I upgraded to the iPhone 4, it wouldn’t work with the FM
transmitter. I never figured out why it wouldn’t work. I would suggest you
continue working with the manufacturer of the device or wait to see if the next
iOS update addresses this issue.
Please feel free to visit us again if you have any other
questions.

Can not specify the SMTP server port, username and password for my SharePoint 2013 web application

We have our SMTP server under port number 141 and we should add username and password. but inside SharePoint 2013, I can only define the SMTP server name , from email, reply-to . But there are not fields to define the port number , the username and password.
So can anyone advice from where I can define the port number and other field settings for the SMTP server ?
Thanks

i am no sure about user name and password. i never saw that option.

Can receive but can't send mail via BT Yahoo SMTP server port 995

Suddenly I can't send mail from my BT/Yahoo account but can still receive mail. The message that i get is that it was rejected by the server. I have not changed the server - it is still SMTP via port 995, using SSL. Help!! Why should this have ocurred out of the blue and what do I do?

Hi Dancing Brave,
Thanks for visiting Apple Support Communities.
I recommend starting with the steps in this article if you are not able to send mail:

Mail smtp server port problem

I just changed isp provider and I am trying to use mail with my yahoo account. Everything seems to work except sending mail. I have talked with Yahoo and Adelphia and they can not figure it out. Adelphia suggested that my server port was blocked but I don't know how that could be because it was working with my last isp verizon. How do I unblock port 25 if that is the case or do you have any other suggestions?

Most, if not all ISPs block the use of SMTP servers that are outside of their network (or not provided by the ISP) on Port 25. Some ISPs allow the use of an authenticated SMTP server only that is outside of their network on Port 25 but some block its use regardless.
These restrictions are in place as part of an overall effort to prevent spam emanating from the ISP's domain.
You cannot unblock using Port 25 with an SMTP server that is outside of your ISPs network. If using an SMTP server that is outside of your ISP's network is blocked by your ISP on Port 25, only your ISP can do so.
Are you also accessing an email account and SMTP server in Mail that is provided by Adelphia and if so, are you able to send mail with your Adelphia email account?
If so, sounds like the person you talked to with Adelphia does not know what they are talking about.
Something to try.
Go to Mail > Preferences > Accounts and under the Account Information tab for your Yahoo account preferences at the SMTP server selection, select the Server Settings button below.
Enter 587 in place of 25 in the Server Port field and when finished, select OK to save the changed setting.
Test if this resolves the problem. If not and you are accessing an email account and SMTP server in Mail provided by Adelphia and you are able to send messages with this account, select/use Adelphia's SMTP server to send mail with your Yahoo email account which is invisible to all recipients.

CVP Call-Server Port Utilisation issue.

Hi Guys,
I seem to have an issue I cant find an answer to. Our CVP Call servers dont seem to be releasing their ports for utilisation, we have 1000 ports per CVP call server and the available ports just keep getting used up until it hits the max threshold. At this time the call server fails, the only way to resolve this issue thus far to release the ports is by restarting the call server. Any Advise is much appreciated.

Hi David, the version is 7.0 (2) with ES 22. We are taking on average 5 calls per min. The license ports are being used and not released it seems, please see attached picture. The available licenses keeps decreasing until all licenses are in use and then the call server goes in to partial service.

Changing SMTP Server Ports When Setting Up New Accounts

My ISP, COX Communications, blocks port 25 for email accounts not using their SMTP servers. When setting up a mail account how do you change the port? I know how it's done when you have the account set up, but not when you're trying to set up the account.
Note that I can think of a way to 'cheat', but having to 'cheat' doesn't sit well with me. It's a clutzy solution to a problem. Let people change ports during account set up should that prove necessary.

HI, all you can do is let Mail go for however long it needs to after making the Account, (half hour here on both send/receive), before it figures out to continue, so you can get to the Advanced Tab!
Or make the Account in say Eudora & Import it.

Connection to outgoing smtp server

I am having problems connecting to smtp servers from my home network, work network and other networks while on the road. I am able to connect with wireless networks without problems, can usually send email through my POP account and occassionally receive via SMTP - so my problem is intermittent.
I receive the normal error message (as an example): "Cannot Send Mail The connection to the outgoing server "smtp.comcast.net" failed". I have full Wi-Fi signal strength, am able to send/receive with a wireless laptop using the same network and same account(s), have tried turning 'off then on' Wi-Fi, 'on then off' Airport and have turned 'off then on' the iPhone. All of this without any luck - Then without making Any changes and while the phone is just sitting on the table, the mail message is sent.
Is there a fix for this problem?

As a test, I just manually created a POP account on my iPhone that I haven't previously used to access this account.
When the account settings were being verified with the provider, I was prompted that the email account does not support using SSL and do I want to set up the account without using SSL.
It seems the iPhone automatically selects Use SSL for the incoming and outgoing mail server when manually creating an account on the iPhone as a default which is verified with the email account provider - which is good and a "smart" feature since it is preferable to access an email account that uses SSL for the incoming and outgoing mail servers with a portable device - laptop or iPhone, etc. especially when connecting to public WiFi networks.
I proceeded to create this account with the iPhone without using SSL. MD5 Challenge-Response for the SMTP server was selected automatically along with 587 being added to the SMTP server - which I did not specify when manually creating the account - since there is no way to do so - but theses are the settings supported and used by this email account provider - all done automatically by the iPhone which is a good thing.
Long story short, if this was automatically selected when creating the account at home - use SSL, apparently this is supported by Comcast but strange that it isn't supported likewise for their SMTP server.
You might try deleting and manually re-create the account to see if this makes any difference.
As long as you use an authenticated SMTP server and 587 for the SMTP server port, you shouldn't have problems sending messages anywhere - via any WiFi network or when connected with EDGE but there can be an exception with WiFi networks. Some may block the use of SMTP servers that are outside of their network regardless if the SMTP server is authenticated.
Receiving should never be a problem so if Use SSL works for the incoming mail server then use it which is a security feature.

Can I set up a smtp server in my computer?

My smtp is never working, I am wondering if I can set it up so my computer can send the email without having to log onto some distant places and hope my email will actually send...
thanks

As Ernie provided, try changing the SMTP server port used by the SMTP server from 25 to 587.
Go to Mail > Preferences > Accounts and under the Account Information tab for the account preferences at the SMTP server selection, select the Server Settings button below.
Enter 587 in place of 25 in the Server Port field and when finished, select OK to save the changed setting.
If this doesn't work and your neighbor will not provide his/her ISP's SMTP server to enter and use to send messages with your account (which is invisible to all recipients), your options are using webmail access for the account to send messages or using Postfix Enabler.

SMTP Server issues on iPhone

I use an IMAP email account administered by my university and I have it set up on my iPhone 4. The incoming mail server works fine on both wifi and 3G but the smtp server only works on wifi. If I attempt to send a message while on 3G the phone attempts to send for about 5 minutes and then gives up. I called TELUS and they had me add their smtp server smtp.telus.net which works fine for sending emails on 3G but an error message pops up when I try to use it on wifi.
I currently have my university smtp server as the primary server and the TELUS server as secondary and this works ok except that when i try to send a message on 3G the phone tries the university server for at least 5 minutes before switching to the TELUS server. If I set the TELUS server as primary the phone gives me an error message right away if I try to send on wifi and won't even try the secondary server.
Does anyone know a way to make it so that the phone will send the message with the correct server without waiting 5 minutes to send each message?
Thanks

With one of my users this same issue was occurring.
No matter if he used ATT primary SMTP or our SMTP server as a primary/secondary, going from 3G to wifi and around the environments through out his day would always end up with either side going well and the other end not sending at all.
We used this work-around I saw posted in some other forum:
Disable the primary (whatever SMTP it is set to) SMTP selection.
Put both 3G SMTP and local SMTP as secondary servers and active.
For some reason if the primary fails to connect, the switch to secondary does not seem to occur or does not occur within the time-out period causing mail sending errors. With the primary SMTP setting disabled, both servers in the secondary list will be checked promptly with no issues.

How do I delete multiple copies of a SMTP server under iOS 7.0.6 on an iPhone 5S?

I have a conflict in trying to set up email using the iPhone mail application. I had to change the password for the email account, which was done via the host's control panel. I am able to send and receive mail (POP) via the computer and logging in through the provider webmail. I have deleted the mail account multiple times on the iPhone and keep getting an user authentication error when setting up as new.
The only was to fix this was to revert back to the password originally in use prior to the change. The provider was watching the log files as I tried to change the settings on the iPhone and also was seeing the user authentication error when using a new password. Once I changed it back to the old password, all worked fine.
They think that because there are now multiple instances of the SMTP server listed, that the login is actually pulling the info from the old SMTP server info, even though all the others are turned 'off' in the settings.
I can find no way to permanently delete all the instances of this SMTP server so that I can set the account up as totally new.
How do I do this?
Thanks.

All of the sudden, my itunes digital copy movies are on the iPad (were not before upgrading), and there is no button to delete them. They are not set to sync through iTunes, and i cannot get rid of them.
Are you sure they are on the device? Sounds like they are just in iCloud. Do they have a cloud icon next to them? If they do they aren't on your device and as such not taking up space. If you don;t want to see them you can go to Settings->Videos->Show All Videos and turn it off. This will hide all your iCloud movies from the videos App. but again they aren't really on your device.

Lastly, with the new Video app, how can i get it to list the name of the movie on the listing screen under the picture? I have to tap a movie to find out what it is. I NEED to be able to see the movie names without having to touch each one individually.
Thanks.
Unfortunately that's not something you can change. To see the titles you need to tap on the movie. I guess Apple assumes the cover art already has the name so there is no need to repeat it.

Iphone mail SMTP server issues

Had my iPhone for a few months and works generally how i want it to, however one small thing that annoys me!
My email account is from my personal domains pop3 service ie [email protected] and messages can be received and sent perfectly via edge in the UK using o2's smtp server, if my phone is connected wirelessly to my network when i'm at home sending messages will fail, I know thats because it cant use o2's smtp server but whats the solution?
My domains pop3 email doesnt have its own smtp server so on my mac i use my isp's one and it works fine but the phone wont let me add seperate smtp one for edge and one for wireless.
Any suggestions?

That wouldn't help, as it would only work for your home wireless. It would not work at other wireless access points.
You can subscribe to a 3rd party SMTP server for a small fee. If you have a gmail account (which is free) you can use their SMTP servers.
Have you tried using your ISP's SMTP server with authentication? Many (but not all) ISPs support this.

TS2756 Tethering. iphone5 email smtp server issue

I have an wifi ipad 2 and an iphone 5 on EE 4G network. I have configured the iphone 5 as a wifi hotspot, I can connect my ipad, browse the web receive emails etc. the problem comes when I want to send emails, it keeps telling me there is a network error. I know this is not true, I have a feeling it has something to do with SMTP outgoing server, possibly the port number? The incoming servier is port 110 and I have outgoing set at port 587 but think it could be some other port or some other issue. Would appreciate any help anyone can shed on this issue
Richard

My problem has been resolved.
Regarding that, probably you should check with SMTP server admin.
For me, the shcedule was success but didn't receive mail. I think the SMTP server admins cleared any firewall filters.
Not sure. Please check with your SMTP server admin.

I have seen all the early responses to how to fix AOL mail issues on Iphones, however no mater how many smpt servers I set up or on .... I can not get AOL mail to send from my Iphone 5, running IOS 6. I have an Iphone 4 running IOS6 and it works fine...

I can not get the Iphone 5 to send out aol mail. I have added the extra smtp server as suggested and it still will not send mail.

I am having the same problem. Sometimes it works and sometimes it doesn't. I called apple restored my phone to its original and it did not work :-( Now it seems like it worked for a bit than stopped again. Now I have to contact Apple again to set up an appointment at an Apple store because it may be an issue with my phone. I have only had it for a week and half!

Rochester/Roadrunner Issues with SMTP Server

Hello. New to Rochester and Roadrunner. I let Mac Mail setup the account but it couldn't resolve the SMTP server on Roadrunner. I can receive but not send. I've played with all of the port and SSL settings and still nothing. It shows my account as "offline". My Comcast account is still on there and a few emails went through, but using the Comcast server for some reason.
I know my password is correct as I've double checked it. I've also pinged the smtp-server.rochester.rr.com. Still won't go.
Any thoughts?

I'm having the same issue with the outgoing mailserver in Rochester. I didn't understand your resolution. Would you please explain further?
Thanks!

Hello, skifmli
Thank you for visiting Apple Support Communities.
I understand that you are unable to sync your iPhone and receive an error. I was start with restarting iTunes and your computer. Once this is done, test the results by attempting a sync. If the issue persists, go through the troubleshooting steps in the article below.
