Cannot send mail via wi-fi at work

mail works perfectly at home (d-link wifi time-warner cable modem). at work, receives normally but will not allow me to send. administrator says it's my macbook pro to blame- nothing from their end to stop mail from sending. any ideas?

Actually, a lot of ISPs have for years and years only allowed use of their SMTP servers for mail originating from their own IP address pool. It really has nothing to do with spam - ISPs only want to pay for processing SMTP services from their own paying customers. So IPs outside of the ISPs domain(s) are automatically blocked. As I say, this has been common among many ISPs for a very long time.
Does the ISP use authenticated SMTP? If so, make sure you have your mail app set to use your userid and password when sending mail. Again, many ISPs will allow authenticated SMTP requests from any IP address (while when you are at home, it may not be necessary, as your IP address allows for unauthenticated SMTP access).
Alternatively, as suggested, just setup and use your employer's SMTP server when at work.

Sending mail via forms no longer working

Recently, on one of our servers (XServe G4 - 10.3.9) was running both web and mail. Mail was moved off of the server 2 days ago onto a newer server (10.4.7)
The web server has: php4.3.11 and is ONLY running AFP/OD/Web
Since the transfer of the mail server to the new machine, all web sites can no longer send mail via their scripts (either by sendmail, php's mail(), or by connecting to SMTP server via php).
The web logs do not show errors when it attempts to send the mail...
A look at mail.log shows
"relay=cyrus, delay=2558, status=deferred (temporary failure. Command output: couldn't connect to lmtpd: Connection refused_ 421 4.3.0 deliver: couldn't connect to lmtpd_)
As far as I'm aware, the web server/sendmail shouldn't be attempting to use cyrus at all. For the record, Cyrus master is not running.
All users can access the mail server without any difficulty. DNS entries have been checked and double checked.
Does anyone know why sendmail and php mail functions stopped working? I really need to get these web forms functioning again. Is the problem with apache, php, sendmail or something else?

Hi Camelot,
Thanks for the quick reply and useful suggestion. I did as you mentioned and fired up the mail server.
The mail "delivered" however, I notice a couple issues in the logs (mail.log)
issue #1: I have to start cyrus master manually via > sudo /usr/bin/cyrus/bin/master SA and command line start/stop of mail does not start master. Also, when starting master from command line as mentioned, terminal hangs.
issue #2 (from mail.log) - still getting the same lmtpd error (but messages do finally get delivered):
Jan 14 03:58:24 www postfix/pipe[2914]: 3503858502D: to=<[email protected]>, relay=cyrus, delay=5327, status=deferred (temporary failure. Command output: couldn't connect to lmtpd: Connection refused_ 421 4.3.0 deliver: couldn't connect to lmptd_ )
Jan 14 03:59:39 www postfix/cleanup[2906]: B60AE58572B: to=<[email protected]>, relay 123.123.123.123[123.123.123.123], delay=0, status=sent (250 Ok: queued as 9FBF41BCBCA)
Do you think these are "issues" to contend with or are they "normal" occurances?

Cannot send mails via IMAP but can receive mails

HI All
Having Exchange 2010 SP2 on standalone box on W2K8R2-std sp1
We enabled IMAP and POP3 for our user base who do not have Outlook or are facing issues with active sync.
mailbox gets configured however none of mails are sent via IMAP they remain stuck in user outbox only.
They can receive mails but can't send. we tried configuring same users on Outlook and activesync and it worked.
We were surprised with some mis-configuration at IMAP end but could't get to root of it. Any idea what could be an issue????
for imap testing we tried Zimbra 7.2.3 on windows 7 pro, Windows Mail app in windows 8.1. IMAP in windows phone 8
Have enabled IMAP and pop3 logging but couldn't interpret it.
Cheers VP

Hi vp89,
Based on my knowledge, POP3 and IMAP cannot be used to send messages.
E-mail applications that use POP3 and IMAP4 to send messages rely on the SMTP protocol to send messages.
The connector for receiving e-mail submissions from client applications that use POP3 or IMAP4 is created automatically on every Hub Transport server.
We need a Send Connector.
More details in the following articles:
Understanding POP3 and IMAP4

Hope it is helpful

Cannot send mail via my Hotmail

Just got a Macbook and can't send any messages either in Mail or Entourage. Can receive but it says there is a 'HTTP error. The request cannot be fulfilled.' I think the settings are correct interms of the SMTP etc etc but obviously not. Can anyone help.

I used to a use a plugin to get my hotmail. Check out the link below:
http://www.versiontracker.com/dyn/moreinfo/macosx/18189
Pay attention to the comments also there are some interesting notes.
I have since terminated my hotmail and changed to IMAP gmail which is something I would recommend. Hotmail has very limited features unless you pay. Most notably no forwarding or folder syncing.

User in france cannot send mail

This is odd. An employee moving through France (we are in UK) cannot send mail via either of our servers. The can collect - no problems. If they come on via one of the VPN systems we have, they can send mail. There is nothing on the log files to suggest there are any problems - e.g. no reject, not even a connect message. They can send email via another service provider which 'suggests' the IP provider they are using is not blocking SMTP. Anyone any ideas?

The mail server that works is not mine so we don't have access to its settings
Eh? Server? No. Look at the client itself. And at the mail client profiles that are set up to access the mail server. You have a known-working profile within a mail client for one mail server (not yours). And a non-working profile (for yours). Compare the two profiles.
There are a number of a ways a mail client can be configured (ports used for reading and sending mail, which protocols), and (barring cases of an unusually locked-down client) you can usually see the settings for the profile (if not the passwords) for the mail server(s) that the client knows about.
Some ISPs and some businesses can block outbound connections to port 25, for instance.
If you have a profile that works, see if cloning that approach on your own mail server works, or if switching the client over to that connection approach if that path is already enabled on your mail server.

Since upgrade to iOS 7 Email error on over 100KB emails "Cannot Send Mail The message was rejected by the server because it is too large." Connecting to Exchange via Activesync

Hi,
Following the upgrade to iOS 7.0.3 on all our iPhone and iPad devices, it has been identified that when sending emails around 100KB in size and over an error message appears on the device stating “Cannot Send Mail The message was rejected by the server because it is too large.” See error message below. The send/receive limit is over 10MB so this is not the issue.
We are in an Exchange Environment using Microsoft Activesync. This issue is not evident in iOS 6. This has been tested on an iPhone 3GS running version iOS 6.1.3. We have been unable to repeat the issues seen on iOS 7 on the older OS. It is not possible to roll back to the older operating system as Apple are no longer signing the software.
We use Microsoft Active Sync to connect to our Exchange servers through a TMG. The issue is very inconsistent, some identical emails go through, some fail. This is not an issue with the send/receive limit as this is over 10MB. The error message when it fails on the TMG is Status: 413 Request Entity Too Large, which we believe is from IIS on the CAS server.
Does anyone have any suggest course of actions to take?
Many Thanks

This resolution have to attend at the server not with the ios device. My employer's mail administrator reject me to correct it from the server. As his concern is, if ither ios devices works why don't mine? So I am helpless than changing my iphone. It works fine for early versions of ios and with androids. And also one of my friends iphone4 with ios 7 (similar as mine) works too. So I guess it's something wrong with my iPhones settings. But basic question I cannot understand is it works in my phone before this ios7 upgrading. And currently working with my yahoo account too. Favourable reply expected.

Get the correct mail server settings from your IT department.

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.

Alias address from iCloud alias address cannot be used to send mails via iPad

Alias address from iCloud alias address cannot be used to send mails via iPad

If you still have this concern: You can only use the alias address linked to the main iCloud account that you backup your iPad to. You can check that going to Setting-iCloud and check the Account email address.
I think this restriction is rather rediculous. I don't see why we can't configure an alias from a different iCloud account the same way we do for a Gmail account. I hope Apple fixes this in iOS 6.

TS1307 cannot recognize mail password and will not send mail..iphone and web work mail no problem

mail will not send and continuously asks for password and rejects last documented password change. I cannot send mail only receive it on the MacBookPro BUT...I can get web mail and use send on iphone...mail cannot be recieved on iphone now.
help thankss

Use the Apple Mail Connection Doctor (Apple Mail's Window menu > Connection Doctor) as a first step.
Also recognize that Apple Mail tends to (also) toss out the same password error dialog for errors other than password errors. This means that network errors and network configuration can be reported as password errors. (And folks that receive the password errors can then reasonably try different passwords, which means that the wrong password can (also) then get recorded in Keychain.)

Suddenly cannot send Mail

I'm in a tech support loop. Qwest is my ISP, Emerald Webhost is my domain host. My outgoing SMTP server is mail.mydomain.com (at Emerald). Suddenly, a few days ago, I can no longer send mail via Apple Mail from my DSL connection. These two laptops can send using mydomain.com from other connection points (cafe's). The ISP and Webhost tech supporters cannot find any problems, so I turn to this forum.
Internet connection is fine - browsers all work as always.
Incoming mail works as always.
Outgoing mail at my DSL connection returns the "cannot connect on server mail.mydomain.com . . ."
Get Mail before hitting the send button does not help.
Hard reset and reconfigure of the Qwest 2Wire modem did not help.
Same problem on wireless and ethernet at this DSL connection.
I'm using ports 110 and 26, as always.
Both Macs on this DSL connection developed the problem at the same time.
None of the modem or Network or Mail prefs/settings were changed on the Macs.
The laptops send just fine via the mydomain at other connection points (cafe's, libraries).
Reentering passwords in Mail Prefs and at mydomain did not help.
Any ideas?
Thanks

Many ISPs are refusing to pass mail to SMTP servers other than their own - when I am at our place in Laguna Beach I have to use the COX cable SMTP server for all of my outgoing mail - they will not let me connect to any of my POP account SMTP servers - have you tried using the Qwest SMTP server? that may be the answer
Since two Macs started having this problem at the same time that makes it look like a change on Qwest's part

Unable to send mail via .Mac

Love my new iPhone. Everything seems to work just fine. I can't, however, send mail using my .Mac account (I receive mail just fine). When I attempt to send (using Edge), I get an error, "Cannot send Mail - the connection to the outgoing server 'smtp.mac.com' failed." One would guess that I've got some setting incorrect, but I can't see what it is. My Yahoo and GMail accounts seem to work just fine, both sending and receiving mail. It's just the .Mac account. Any suggestions? I suppose I could delete the account and try again, but there must be something not right. Any Ideas???
DukeM

Did you manually create your .Mac account on the iPhone or transfer your .Mac account settings from your Mac to the iPhone via the sync process?
If the latter, what are you using for the server port for .Mac's SMTP server on your Mac?
If not 25, change it to 587.
If you manually created your .Mac account on the iPhone, use this for the SMTP server.
smtp.mac.com:587
Add 587 to the SMTP server separated by a colon.
I use this to send with my .Mac account on different WiFi networks and via EDGE with no problems.
