Does anyone use a Mac? Problems sending email

Are they just in the outbox? Are you using Mail.app (the default mail client in OS X)?

I'd hazzard a guess and say that it's your SMTP (send mail) server settings. Who is your ISP? What domain does your email address end in? (like mine is @gmail.com).

Hi Chris
Yes just outgoing mail,
Yes using Mail.pp
ISP is 'Easily' SMTP is smtp.easily.co.uk

Is it full!? A large file blocking all others? Look at your folders and maybe do some clearing. Although it would warn you.
Mail server setting for sending are incorrect as Chris says above would be my guess.

Can't see anything on their site, but perhaps they need authenticated smtp? - enter your ISP/Email username/password in Mail -> Preferences -> SMTP server (open the drop down list, and select edit), click advanced, in the authentication dropdown list - choose password, then enter your credentials there. If that doesn't work, what is the error message?

Virginveggrower; no not full.

Chris; tried that, its so frustrating.

I'm still waiting to hear back from Easily.

This is the error message; could not connect to this smtp server.

Just read the error report and it says; EHLO unknown and lots of other computer speak, another one says '501 syntactically invalid EHLO argument'

What port is configured? 25?

Could
You post the whole log from start of the connection? The EHLO is like "hello" when a connection is made.

here goes;

What are you entering as your username? Sorry about the delay was bathing the kids

Edit: try it without the @easily.co.uk, or with if you don't have it on there. If you have a full stop in the email address make sure it's a full stop and not a comma. The only special characters allowed in an email address are "-", ".", "+" and "_" off the top of my head.

Edit2: is your send mail server set as easily, or your yahoo one? -- when you're sending the email, are you selecting to send from your easily? 99% of ISPs will not allow you to send from another domain via their send mail/relay servers, so if you're set to send via easily, and you're composing from your yahoo that'd cause issues (unless there's a trust between the two)... Probably not related (I'm guessing either a username or password issue - might be worth logging into the web mail, and if that works, copying and pasting the user into the send dialog settings in mail.app).

Failing that, I'd suggest trying another mail client to make sure it's not an issue with mail.app's smtp protocol (though I highly doubt that, as mail clients are made to work with smtp (send mail protocol (protocol being the language, or syntax used to communicate)).

Edit3: Is it a secondary email address setup on your isps mail account? If that is the case, then try using the primary username/password in the send settings. Maybe a screenshot of the dialog (send mail) would be helpful..

Edit4: - final edit!

I'm 99% sure it's a username issue, as the SMTP server is saying it doesn't recognise the HELO and the EHLO command.. HELO is a basic set of instructions, with EHLO being an optional, more advanced set (which I'm guessing is things like sending SSL-based email -- looking at your TLS stuff, I'm guessing you are sending secure emails).

Well, Oh has spent hours on this; nothing is working. Trawed the interweb and there are loads of other people with the same problem, apparently a 'mac' bug!

Given in and downloaded Opera mail client, put his settings in and its working!!!!

I know its very annoying, Macmail should work but it doesn't. I'll have another go when I'm not so desperate for time, keep you posted too.

Many, many thanks for your help one & all
