This explanation sounds "strange".

I know about the length limitation in the folder format, but I see no reason why it shouldn't be possible to store a reasonable string there.

Nevertheless thanks for investigating (likely not being worth the effort).

Hello All,

more and more often the subject of mails is not displayed in the overview. Maybe UTF-8 encoded subjects are the reason.

Can anybody tell me whether that's a general problem in Pmail or maybe only my installation?

If the former: Is it an error in Pmail or wrong encoding in the mails?

TIA,

Oliver

What are you calling overview, list or preview? What is being displayed elsewhere? Is everything else normal? Do you have any AV scanning in place?

classical or three pane doesn't matter. Nothing is displayed in the "Subject" column of the message list. The subject is displayed in the message window.

AV scanning is not the reason.

In the mean I can generate such messages using current Thunderbird, Subject "Re: xxxxxxxxxxxxx xx xxxxx xxx xxxxxxx xxxxxxxxäxxxx" and UTF-8 as encoding.

Maybe Pmail doesn't process folded Subject lines longer than 75 characters.

if anybody wonders why this posting was about the IMAP stuff before I edited the content: That was not intentionally. I edited the IMAP posting in another browser window, got an AJAX error, reposted. Maybe the forum software doesn't like parallel editing of two postings.

If it only occurs in folders other than the new mail folder it's due to the current limitations of Pegasus Mail's mail folder format.

No, it happens in the new mail folder as well as in other folders. Do you want a test message?

Maybe it's a misinterpretation of  RFC 2047 either on the side of Thunderbird or Pegasus since it happens if the folded subject line is 76 characters long (excluding CRLF).

If CRLF belongs to the 76 character limit, then Pmail has one spare character. If CRLF belongs not to the 76 character limit, then Pmail might be wrong.

David Harris just recently mentioned that "encoded words" (UTF-8, e.g.) are supposed to not exceed 76 characters IIRC, it would probably be enough to just provide such an encoded  subject line for examination here.

the example I already gave translates to:

Subject: Re: xxxxxxxxxxxxx xx xxxxx xxx xxxxxxx =?UTF-8?B?eHh4eHh4eHjDpHh4?=
 =?UTF-8?B?eHg=?=

Removing one "x" makes the subject visible.

Addendum: RFC 2047 says:

"An 'encoded-word' may not be more than 75 characters long"

"each line of a header field that contains one or more 'encoded-word's is limited to 76 characters"

But moving the encoded word to the beginning of the subject contents does so as well, so I believe this is not only a length issue.

If someone takes the RFC text

"The length restrictions are included both to ease interoperability through internetwork mail gateways, and to impose a limit on the amount of lookahead a header parser must employ (while looking for a final ?= delimiter) before it can decide whether a token is an "encoded-word" or something else"

as an implementation guide, it could be the reason.

David Harris' comment on this issue points to the folder issue I mentioned earlier in this thread, so it's unlikely that a fix will be provided before v5 is released with its new mail storing mechanisms.

Could you please elaborate on this issue?

You wrote "If it only occurs in folders other than the new mail folder", but it does happen in the new mail folder.

No, I can't, I'm simply quoting David Harris here after providing the details gathered in this thread.
