Re: Corrupted links in emails

Just for the record, I've now installed version 11.12.2. Verified base64 works with sendmail using my test mailing list and then tried my set of 40 test emails - all were received uncorrupted. Reverted to quoted-printable and corruption returned (as expected). I've left my active mailing lists with ...

Re: Corrupted links in emails

Yes, getting SMTP working effectively solved the problem we've being having at last - it's been a frustrating experience at times but I'm happy we've got a solid explanation of the root course so can be confident corrupted links won't re-occur if I use SMTP mode. Thanks for your help - I've certainl...

Re: Corrupted links in emails

Thanks for reply and suggestions. I accept the issue may be with the sendmail implentation. Sadly "man sendmail" just gave me "No manual entry for sendmail" Given I'm using a shared hosting package, I'm not sure I'd be allowed to change anything anyway. I also tried setting Base64 in "Sending->Advan...

Re: Corrupted links in emails

Now I have a file of the Dadamail output which would normally go to sendmail, I've used command-line to submit it to sendmail (to prove I could, and that the errors were still present by this method), then I modified this Dadamail output file using a text editor to replace '\n.' with '\n=2E' (4 repl...

Re: Corrupted links in emails

Just worked out how to run a perl snippet on command line (I admit to knowing very little about perl) and tried myself - unfortunately it looks like it doesn't convert a dot at beginning line followed by other character to =2E, so I don't think it will solve the problem I'm seeing. ~$ perl -MMIME::E...

Re: Corrupted links in emails

The test case for the errors I've seen would be something like Data => "\n.abc"
i.e. a line starting with a single dot followed by other characters.
Does the dot in this case also get converted to "=2E"?

Re: Corrupted links in emails

Thanks for reply - nice demo.
So if single dot is already being replaced by =2E in SMTP method, that would explain why I don't see missing dots with that method.
Please could single dot to =2E also be applied to sendmail method - I expect that would cure the problem I'm seeing?

Re: Corrupted links in emails

As suggested I captured as a file the output dadamail would have sent to sendmail (emailed file direct to Justin) The data has been split into lines of 75 characters from submitted code followed by an "=" (I guess this is Quoted-Printable format). Significantly I can see that when the 1st character ...

Re: Corrupted links in emails

I've now created and my my experiment with matrix of synthesised testcase emails to cover "dots" in every possible position in email body. Initial conclusions: A: With a few exceptions, the error occurs when a dot falls on a matrix of positions with 71 character spacing. B: If I select sending->opti...
