For the last two days I watched as Leopard’s Mail.app tried to download 1 email at an average of 1kb per second.
My internet connection in general was fine yet it looked like it was going to take Mail the entire duration of Lent to download this email.
I figured I must have a setting wrong. I checked Google’s IMAP configuration instructions for Mail 3.x on Leopard. No Joy.
I tried using the information they provided for Mail 2.x setup. Those emails were still crawling down.
Finally I checked Google’s details for configuring other IMAP clients
It says you can use either port 465 or 587 for outgoing mail. I had been using 587, so I changed to port 465. Hey presto! Emails are now flying down. I don’t understand how a dodgy setup for outgoing mail could affect my incoming mail but I’m more than relieved to see Mail.app doing it’s thing now.

How do you find the overal speed of gmail imap with Mail overall after downloading all the headers? Mine seems fine for a bit then incredibly slow after .

@James
It seems to be ok now. Changing the port as mentioned above seemed to help, although logically I can’t see how. Sometimes my mail still comes down painfully slow but then again the throughput of my pityful 1mb BT Ireland broadband connection resembles a leaky tap.

I have been using gmail imap for a number of weeks and it has been fine. Over the last 24 hours, it has got really slow. It is taking 20 times as long to do anything and i know that my internet connection is not the problem.
I have the correct email port. Any ideas?

@Alex, sorry man no idea. The settings above did the job for me, I’m not sure what else to do.

It worked fine for me!

I cant see anywhere to change the port number, I changed it to 465 under mail prefs and that stopped anything from working, couldnt connect
Ive read that “And it is certainly a Mail.app issue. Gmail IMAP loads quickly and reliably under Thunderbird for OS X. Mail.app is the problem”
Its soo slow and rediculously buggy, might have to switch to Thunderbird I think, Ive always had issues with mail
is yours sill working sweet?

Chris:
Mail.app 4.3 does switches between ports 25, 465 & 587 by default but you _can_ force it to use 465 if you’re getting this crazy slow behaviour – I was until about 5 minutes ago when I changed the ports.
preferences > accounts > account information
select your gmail account in the left pane
the bottom section of the right pane is “outgoing mail server (smtp)”
select “edit smtp server list…” from the drop down
select the relevant sever in the top section
click the “advanced” button in the bottom section
check the “use custom port” radio button
click “ok”
quit preferences (remembering to save your new settings on your way out)
Hope that helps

Interestingly enough this problem is still manifesting itself. I have had problems with gmail access via imap being really slow for the past couple of months with mail.app and thunderbird4.0, 5.0, and 6.0 over a 100Mb connection. I actually switched from 465 to 587 and it stopped being so slow.
This leads me to believe that google’s smtp servers may be getting overloaded and the apps are getting stuck in a wait state trying to send updates to status for emails (ie. mark as unread). Outside of that theory, I have no idea.
Thanks for the info in the post!
