Topic: Repeat Emails SME 6.0 IMAP + Clam/Amavis

[gbentley]

Hi,

I have tried searching on 'repeat emails' and other similar keywords but cant find anything quite like this.

I have a client with a SME 6.0 box that had Japsers Clam/Amavis script run against it. It all worked fine for months but now I am getting lots of phone calls about emails repeated or delivered very late. I have checked the domain ISPs box which is working as expected although occasionally mail is not deleted from it and I have to manually remove it. This all started a few months ago after being fine for over 6 months.

I am hopeing someone else has had this and found a solution as I have started sifting thru logs but am not really sure what to look for.

Any help / advice really appreciated !!!

I have run into a similar problem occassionally,

does it do this consistantly ?

What does your "status of mail queue" log look like ?
if you see alot of email sitting in the queue?
also, what does your smtpfront-qmail log look like? does it show 2 entries for the double messages ?

As for the late delivery, there could be a few causes. I have had the qmail daemon die if there is a ton of email built up in the queue. watch the status of it during a busy day. Also, what kind of email volume are we talking about, and how beefy of a server for it ?

One of the things that I figured out that if they were using the webmail system (horde &imp) sometimes employees would click send on the message that they wrote, get impatient after like 5 seconds and click again before the window closed. my boss complained to me about double and triple emails.

Hi, Sorry about the delay !

This is part of the whole issue - there is nothing that can be pin pointed with any regularity - its all very sporadic.

I will be going back tomorrow to look at the logs within the server manager.

Also, I think you could be right about very large messages - its a firm of Architects and they email anything from 4 to 10 meg mails.

In some cases a reboot has cured the repeats - as for the delays I cant really say when / how / how frequent they are happening because I am across town.

As an aside they are using Lookout Excuse as the client in IMAP config.

I have gone back to using POP3 because so many of them where using the mail server as a personal file server for email - the total last week was 2 Gig !!!

I sent round a memo that all mail held on the server was to be flushed and scared them into saving it properly on the file server (a RH box)

Funnily now they are all on POP3 and the mail is removed form the server there has not been any reported issues (at least non I have been made aware of)


Maybe the IMAP component cant really handle all that mail ?

Thanks for your input mach1 !

Yeah, as far as the IMAP daemon goes, anyone I talked to, with a large amount of accounts has experienced some problems with IMAP. I am going to look into building a better IMAP daemon for 6.01 unless a stable release of 6.5 comes out first. It appears that the rpm for e-smith-imap was a beta.
