Tried both 25 and 587 and still can't send or receive

Are you on your home network or remote? The SMTP server you need to use will differ by location.

Really, you need to read your ISP's configuration information.

I use RR at home and NEVER had a problem using Mail from remote locations before Leopard. Just got off of the phone with RR tech rep who says Apple Mail and Leopard are problematic. Can rceive fine but can't send. All settings are correct and status window states Mail is connected to the smtp server along with the requisite green dot status.

Just took delivery of the MBP Penryn a few days ago and did not attempt to send mail from home but did download same. Pismo w/Panther or Jaguar on the road; no problems as the preference pane will show the correct outgoing server address you entered. We know the settings are correct and MBP states Mail is connected to the correct server; still no transmission capability.

Need some help.

Do you have "SSL" checked next to the place where you enter the port for the outgoing SMTP servers? I'd suggest using 587 and checking the SSL checkbox. Additionally, try using port 993 for the incoming server (set in the "Advanced" tab under the "Accounts" preferences).

Try using 587 for outgoing and uncheck the SSL. When you're on the road using other ISPs, sometimes their servers won't support SSL. Also try using the Password authentication.

Your statements are confusing because you state that you've tried both 25 and 587 and still can't send or receive, but the outgoing port settings don't have anything to do with receiving mail.

Comcast, my ISP, switched us to 995, from 110, for incoming with SSL and to 587, from 25, for outgoing in an effort to reduce spam.

Don't feel bad, I am in the same boat. I found out from my ISP that they block port 25 and 587. (I had to pry for that little tidbit, as the answer was "we are not the only ISP to have this "issue") Charter would not come out and say that THEY were the ones causing my problem. According to their "tech support" which I find useless, I have to set my outgoing mail server to smtp.charter.net. Nothing like forcing PAYING customers to use their e-mail server... Whatever happened to the customer is always right? Boo Charter!

The Ports you have included in the Subject of this topic are those only useful for sending, and not anything to do with receiving. What type of account do you have -- POP, IMAP or .mac? Who is the provider of this account? With some ISP provided accounts, the incoming server must be working before you can then send. What port is your Incoming server using?

Greetings,

Typically, of most of the users that are having issues with their Mail, can receive mail fine but sending is usually the issue. You will need to know the correct port that you need - usually 25 or 587. If you can surf the Web, you can do email.

You will need to check with your home ISP for the correct parameters, if you are at home. If you are at work, or elsewhere you will need to know those parameters in most cases if you want to send because more and more ISPs are blocking all SMTP servers other than their own. I know I do.

If you have Web access to your email, you can use that, and some IMAP mail providers will work about anywhere, but you still need to know the particulars. We block Dot Mac's IMAP to where I can receive email. but I have to plug in the local SMTP server to send anything, because of the local blocking. I don't have any problem with that as it's another layer of security.

There is nothing wrong with Mail 3.2 or Leopard, they are not flaky. The problems are setup and configuration issues - once you know the correct parameters and setup routines, it all works fine.

I have never had an issue of note with Mail or Leopard - I use my Dot Mac mail and Exchange mail, in our Active Directory Domain, at work. I also have a Road Runner POP account that I use as well.

Good Luck - Cheers,
M.

Just passed by the house; Mail sends and receives properly. Phoned AppleCare; no help. Mail only able to send (receives fine) at about one of four locations while on the road. Normally shows good connection to smtp server but my e-mail address isn't recognized. I can only surmise the local server isn't providing the correct info or something is being blocked by OSX Firewall or another security program (Internet Cleanup). Tried reconfiguring and/or turning off IC; no difference. No problems with Pismo running Panther and IC at same locations....?????

Joe,

What port are you using for the SMTP?

Ernie

Ernie,

Port 25 is the RR smtp port of choice. I've switched to 587, etc. as recommended by AppleCare and others in this forum - no difference. Interesting. Ran disk utility and repaired disk permissions thinking this may solve the situation; nope.

Any ideas?

Joe

Joe,

Typically with RR, the SMTP is actually authenticated with the IP of the modem they supply you. This results in the proper method of authentication in Mail Preferences being None and use of Port 25 -- this what you are using when at home, I would think?

However this SMTP provided by RR will not work in very many remote locations -- whether wifi or connected to another ISP -- because those networks will restrict you to the use of an Authenticated SMTP, i.e. Password or similar authentication, and often also block Port 25. This is why many people have .mac, Gmail, or other such accounts which provide an Authenticated SMTP which will be accepted in these remote venues. To use such ports as 587, you must have an authenticated SMTP.

Check with your RR support desk to see if they might have started offering an authenticated SMTP that can be used with those Ports that are not blocked by these remote providers.
