SMTP Hanging during execution

I've used the following email code quite a bit, usually with no problems. The latest program parses a file, and sends the results via email. Problem is, every few runs, the program hangs during the email routine. I believe it gets stuck at the .sendEmail line. No errors, doesn't crash, just hangs up. Usually takes about 20 seconds to attach the file and send the email, I've let it go a few times that it hung up and it stayed stuck for over 5 minutes before I killed it. Am I missing something in this code? As I said, I use this routine alot, just not with a file this large, sometimes it works, sometimes it sticks. grrrr

VB Code:

'send the email
    With SMTP
        .Server = "serverIPaddress"
        .Username = ""
        .Password = ""
        .MailFrom = "fromName"
        .SendTo = "toName" 'bill
        .CC = "ccName" 'chris
        .BCC = "bccName" 'me
        .MessageSubject = strSubject
        .MessageText = strBody
        .Attachments.Add (mailFile)
        lblMain.Caption = lblMain.Caption & " Sending email..." & vbCrLf
        Me.Refresh
        .sendEmail
        .Attachments.Remove (1) 'remove attachment so it doesnt mail again on second pass through
    End With

Thanks in advance.

Just the SMTP component built into VB. Is that what you mean?

Don't know if this would help but i find throwing in a DoEvents will allow anything trying to execute within the system to go forward. Has helped a few of my apps from freezing up

Good point. I'll toss one in there.

I didn't know it was in there for a long time either. Usually because I'm looking at "Microsoft yadayada control". It's in the components, just called SMTPControl. Very handy and relatively simple.

K-mail does it better

Well, it looked like the doevents was making a difference, then it hung up again on a test run. Anyone have any other ideas?

This needs to run with no user intervention, it will run at 2am everyday, so Kmail is not an option.

K-mail do not require any kind of intervention so it might be a good solution to your problem ...

Anyone else?
