Mozilla is not only a great WebBrowser, it is also a great MailClient. Trust me on that one.

I have found MozillaMail to be a pathetically buggy MailClient especially when using multiple IMAP accounts on different servers. I would recommend PINE

I have found MozillaMail to be a perfectly stable MailClient, even when using multiple IMAP accounts on different servers. I have also been using it longer than MattBrown for this purpose. The only times I have had any issues with MozillaMail is when trying to force its folder hierarchy to show subfolders of INBOX to be at the same level. Personally I don't care about this, but MattBrown seems to think that a MailClient is only useful if it shows subfolders of INBOX at the same level as INBOX.

Note that this is arguably a bug in MozillaMail (not supporting the NAMESPACE extension to IMAP4 correctly), however in itself it is not a fatal bug. Some IMAP servers (recent versions of Cyrus for example) can do server-side namespace alteration, which MattBrown is used to.

I would like to point out to MattBrown that 'pathetically buggy' is fairly strong language to describe a MailClient that works 100% fine for other people, who have only had issues with it when trying to resolve a purely cosmetic issue.

While it is true that I have had issues with MozillaMail and CourierImap? displaying incorrect folder hierarchies my problems with MozillaMail have extended well beyond this. The following problems are some of the worst I have experienced with Mozilla and "standard" IMAP configurations. And no I don't run the latest beta versions.

• Crashing when the compose button is clicked
• Refusing to talk to the IMAP server until MozillaMail is shutdown and restarted.

I've seen the second problem you describe, when I am using an IMAP server off a dynamic IP: eg my server at home. If it changes IP, mozilla sometimes requires a restart. If you are using SSL, mozilla always requires a restart. This isn't neccesarily a mozilla problem. It could perhaps handle it better, however dynamic IPs are not designed for running services off them. If you want a reliable mail server, get a static IP or host your mail on a machine with a static IP.

The former one does look like a bug, however I've seen issues like it relating to incorrect XUL. Try removing your .mozilla directory ( you did do this when you upgraded last, like the upgrade notes in Mozilla tell you to, right?) and reloading.

• DanielLawson

I used MozillaMail on my LAN at home and still had problems, so I don't believe that dynamic IP's are the problem.

I have removed my .mozilla directory countless times due to being unable to start mozilla, this only adds to my frustrations with MozillaMail.

• MattBrown

If mozilla mail refuses to ask if you want your password remembered, make sure you don't have the line

user_pref("signon.rememberSignons", false);

in your mozilla prefs.js file!

Annoying things about mozilla mail

• it feels slow, even on a fast machine. This seems to be due to XUL, and can't be helped. Opening a new window isn't as instantaneous as you would expect on flash hardware. Moving another window around on top of moz mail results in noticable redraws. Rendering non-latin characters also seems to slow down moz quite a bit.
• Need to be root to install EnigMail for GPG support. I managed to work around this my making my own moz tree and symlinking almost everything back to the original, but that's a clumsy workaround.
• Can't highlight and select email addresses in the headers summary. Traditionally graphical apps on X let you select text into X's clipboard. I know you can right click, but that's not The UnixWay.
• Integration in SeaMonkey? means that if your browser hangs, all your mail windows do too. MozillaThunderbird and MozillaFirebird? should prevent this.
• If the headers are too wide for the message display window (eg a long name/email address, or attachment filename), mozilla resizes all the internal widgets, making the folder names list thinner. Not only is the jiggling annoying as it sizes and resizes multiple times, it makes it hard to move messages to folders if the folder list is only a few pixels wide.
• If you start Compacting Folders and then minimise moz mail, it uniconifies itself when it finishes compacting.

Ive used Moz Mail under Sea Monkey and Thunderbird, seem's OK (I mean, it dosn't crash like KMail does) -- ReneBartosh
